Frederick Master of Science, December 15, 2006 (B.M., Samford University, 2000) 80 Typed Pages Directed by Robert D. Locy Heat and drought are major factors that affect the annual cotton yield. Cotton farmers are always looking for plants that are more thermotolerant and drought tolerant to increase the yield. These characteristics can be studied in many ways. This study focuses on measuring chlorophyll fluorescence in Gossypium hirsutum as a means to evaluate the desired characteristics of heat and drought tolerance. ?Deltapine DP 90? (DPL 90), a widely grown adapted cultivar was used as a control in this study. 1762 accessions of G. hirsutum were obtained from the USDA SPARS cotton germplasm collection in College Station, Texas. Four to five seeds of each accession were planted in a single pot, with three to four pots per accession. These plants were grown for at least four weeks in a greenhouse. vi Leaf samples were collected from each accession. Chlorophyll fluorescence screening at increasing temperatures was performed on leaf samples of each accession. Plants that excelled in chlorophyll fluorescence were submitted to a traditional whole plant screening process under heat stress conditions. Chlorophyll fluorescence testing was determined to be an effective way to find cotton plants with increased thermotolerance and drought tolerance. However, all cotton plants that perform well in chlorophyll fluorescence testing do not necessarily exhibit the improved characteristics desired. vii ACKNOWLEDGEMENTS The author would like to thank Dr. Robert Locy for his guidance throughout this project.

INTRODUCTION The cotton (Gossypium sp.) industry plays a significant role in our economy, especially in the southeastern United States. It is crucial that cotton farmers are able to maximize their annual production yield for a greater financial gain. Some factors can cause a decline in the annual yield such as parasites and heat stress. The scope of my research is to analyze wild accessions of upland cotton (G. hirsutum L.) and identify genotypes that show an increased thermotolerance when compared to ?Deltapine DP 90? (DPL 90), a widely grown adapted cultivar. The wild accessions vary widely in such characteristics as geographic origin, leaf shape, pollen color, photoperiod response, lint quality and other traits. Any plants that are more thermotolerant than DPL 90 will be analyzed at the molecular level in future research. The molecular research could identify any proteins that are expressed under heat stress conditions in the wild accessions, not found in DPL 90. The genes coding for these proteins could then be identified and used to genetically engineer a more thermotolerant cotton plant that would improve the yield of cotton farmers in the southeast. Any plant has an estimated optimal temperature range of 10? C (Mahan et al., 1995). Cotton plants thrive at a temperature of approximately 27? C. Once the temperatures rise beyond this, plants lose vigor as a result of the heat stress (Smith & Cothren, ed., 234). The productivity of cotton crops significantly decreases as the 2 temperature continues to increase. Plants can compensate for the high temperatures through evaporative cooling. However, if severe heat stress conditions remain for more than a few hours, plants can not sufficiently cool themselves through evaporation alone. This is especially true in Alabama due to the high summer temperatures and humidity. Once the temperature rises past 27? C, various biochemical processes are altered in plant cells. Some of these processes are photosynthesis, transcription, and translation. DPL 90 has been one of the most planted cotton varieties in previous years. Cotton farmers have relied on it and other cotton cultivars because of its proven yield ability under stress. However, there is room for improvement in stress-related cotton yield. When searching for scientific articles on differential gene expression in G. hirsutum, very little information can be found. Cotton farmers and breeders have not yet identified all of the genetic components of cotton plants required for thermotolerance. 3 II. REVIEW OF LITERATURE Responses to Heat Stress in Plants: Heat affects many different functions at the cellular level in plants. Membranes become more fluid at high temperatures because lipid properties change. Enzymatic activity is altered and proteins can denature, causing imbalances in metabolic pathways. Oxidative damage occurs when active oxygen species (AOS) are formed. AOS formation stems from denatured proteins and damaged membranes. Heat shock proteins (HSPs) are also produced in response to heat stress (Larkindale et al., 2005). HSPs will be discussed more thoroughly in following sections. These cellular level disruptions from heat stress decrease the efficiency of photosynthesis. Continual high temperatures can affect flowering. It can also cause reproductive failure and accelerated aging, eventually leading to plant death (Hall, 2001). The annual crop yield of a plant can be drastically reduced by heat stress. The extent that daily maximum temperature rose above 32? C during seed fill and pollination was determined to be the best variable to predict yield in maize (Thompson, 1975; Dale 1983). Soybean has produced the largest yields during periods of the reproductive season with the coolest temperatures (Martineau et al., 1979). 20-30? C has been established as the optimum temperature range in which to obtain the largest yields in cereal crops (Keeling et al.,1993). A decrease in yield can even occur as a result of high night temperatures (Hall 1990). 4 Many areas involved in photosynthesis undergo changes when heat stress is encountered. Due to the complexity of the process and the multitude of affected components, the rate-limiting factor of photosynthesis during heat stress has not been determined. The components that are involved in transferring CO 2 from the intercellular space to the chloroplast have been proposed as the major problematic area (Bernacchi et al., 2002). Other weak areas of interest have been the electron transport chain, the inability to regenerate ribulose bisphosphate (RuBP) (Wise et al., 2004), and the cellular inability to maintain RuBP carboxylase/oxygenase (RuBISCO) in an active state (Salvucci & Crafts-Brandner, 2004). Membrane damage can also occur during periods of heat stress. Isoprene has been shown to protect photosynthesis during brief periods of heat stress in plants that produce it such as kudzu (Pueraria lobata) and red oak (Quercus rubra). This hydrocarbon has also been shown to provide protection when introduced into common bean (Phaseolus vulgaris), a species that does not synthesize isoprene. The protective mechanism of isoprene is unknown, but is thought to involve the double bond present in the molecule (Sharkey et al., 2001). A positive correlation has been found between increased lipid saturation levels and increased thermotolerance of photosynthesis (Murakami et al., 2000). This correlation has also been observed in bentgrass (Agrostis stolonifera) (Larkindale & Huang, 2004b). Some heat-induced transcripts have been induced by increasing membrane fluidity in the absence of heat (Sangwan et al., 2002). This demonstrates that membrane changes as a result of heat stress are involved in thermotolerance. 5 Pre-treatment with H 2 O 2 or menadione can lead to an increase in thermotolerance (Larkindale 2001; Larkindale & Huang, 2004a). H 2 O 2 production is an early response to heat stress (Dat et al.,1998b; Vacca et al., 2004; Larkindale, 2001). These findings suggest that some active oxygen species (AOS) play a role in heat stress-signaling, possibly inducing heat shock proteins (HSPs). In addition to H 2 O 2 , several other chemicals seem to be involved in heat stress responses. Ethylene production has been induced by heat treatments (Dziubinska et al., 2003), and ACC oxidases are upregulated, by heat stress (Nie et al., 2002). Plants pre-treated with abscisic acid (ABA) showed an increased thermotolerance (Robertson et al., 1994; Gong et al., 1998; Larkindale & Knight, 2002; Larkindale & Huang, 2004a), as did those pre-treated with salicylic acid (SA) (Dat et al.,1998; Larkindale & Knight, 2002; Clarke et al., 2004; Larkindale & Huang, 2004a). Heat and changes in membrane fluidity have been shown to upregulate a MAP kinase in Arabidopsis (Sangwan et al., 2002). A kinase that phosphorylates a heat shock transcription factor (HSF) in tomato was found to be upregulated as well (Link et al., 2002). Responses to Heat Stress in Cotton: Heat stress has been shown to retard leaf growth rate and stem elongation, which leads to plants of shorter stature with lower yields and fewer nodes (Reddy et al., 1992; Reddy, Baker & Hodges, 1993; Reddy et al., 1995). A notable response in cotton is the effects of high temperatures on reproductive growth. Plants growing at high temperatures during the period of flower development exhibit drastically lower bud/flower/boll retention. At temperatures of 40? C, all flowers and fruits are aborted (Reddy, Hodges, & Reddy, 1992; Taha et al., 1980; Reddy et al., 6 1993). Heat stress also adversely affects fiber length and other fiber quality characteristics (Bradow & Bauer, 1997; El-Zik et al., 2000; Liakatas et al., 1998). Crafts-Brandner and Salvucci (2000) have shown that the activation status of RuBISCO by RuBISCO activase limits photosynthesis in heat stressed cotton plants. A novel form of this enzyme is induced by heat stress (Law et al., 2001; Salvucci & Crafts- Brandner, 2004). Membrane stability (Hafeez ur Rahman et al., 2004) and antioxidant levels (Mahan & Mauget, 2005) show change in response to heat stress and have been used to evaluate thermotolerance in cotton plants. Differential Gene Expression and Heat Shock Proteins (HSPs): The first evidence of differential gene expression came as result of the work of F. Ritossa in 1962. After a temperature increase in his incubator, Ritossa noticed a change in the puffing patterns of polytene chromosomes found in Drosophila melanogaster salivary glands. The magnitude of this discovery was not fully realized until over 10 years later. In 1974, A. Tissieres identified these puffs as genes expressed under heat stress conditions. Since these genes were transcribed under heat stress, the final products of protein synthesis were termed ?Heat shock proteins? (Hsps). This general heat stress response has been highly conserved and can be found in both prokaryotes and eukaryotes. Hsps primarily function as chaperones involved in the maintenance of protein homeostasis. Heat stress transcription factors (Hsfs) control the transcription of genes that code for Hsps. These transcription factors are found in the cytoplasm and exist in an inactive state until needed by the cell. Hsps are synthesized during heat stress to increase the amount of chaperones available for refolding denatured proteins (Baniwal et al., 2004). 7 More than 20 heat shock transcription factors have been found in plants. This is significant since only three have been found in vertebrates. Only one each has been found in yeast and Drosophila. While the size and sequence of these Hsfs vary, the basic structure and promoter region are conserved. Three ?-helices and a four-stranded antiparallel ?-pleated sheet form the DNA-binding domain (DBD). This domain is located near the N-terminal end of Arabidopsis Hsfs. Hydrophobic amino acids are found in the DBD core, which functions in recognizing heat stress promoter elements (HSE). These promoter elements are located upstream of the TATA box in genes transcribed during heat stress (Baniwal et al., 2004). An HR-A/B region comprises a second domain in Arabidopsis Hsfs. This domain is separated from the DNA-binding domain by a flexible linker. This linker region varies from 15 to 80 amino acids in length. Differences in the linker and H-A/B regions have led to the identification of three classes of Hsfs in plants (A, B and C). Another component of all plant Hsfs is a nuclear localization signal (NLS) formed from basic amino acid clusters. A nuclear export signal (NES) is located at the C-terminus. The NES is composed of hydrophobic amino acids residues and often has an abundance of leucine. The C-terminus also contains short peptide motifs made up of acidic, aromatic, and large hydrophobic amino acids. These motifs are thought to be responsible for the activation of transcription in Hsps (Baniwal et al., 2004). Chloroplasts each have one heat shock protein with a low molecular weight (lmw). The chloroplast lmw Hsp has a unique, methionine-rich domain. Heckathorn et al. (1998) used this information to study the chloroplast Hsp in tomato plants (Lycopersicon esculentum). Chloroplasts were isolated from heat-stressed tomato plants and lysed. An 8 antibody specific to the Met-rich region (Ab met ) of the chloroplast Hsp and one specific to a domain conserved in all lmw Hsps (Ab ? ) were employed. These antibodies were added to restrict the function of the chloroplast lmw Hsp. All chloroplast samples were treated with the antibodies after incubation at control or pre-heat stress temperatures and O 2 exchange rates were measured in the samples to determine the effectiveness of photosynthetic electron transport. The whole-chain electron transport rate was considerably lower at 47? C in all cases. The pre-heat-stressed plants had a lower rate than the control samples at 25? C. However, the rate was higher in pre-heat-stressed plants than the control at 47? C. These data indicate that the pre-heat-stressed plants were slightly more tolerant than the control plants. This observation was most likely due to the production of the chloroplast Hsp in pre-heat stressed plants before the antibodies were added. The control samples were not pre-heat stressed so the antibodies did not have any effect. Heckathorn also wanted to know if the chloroplast lmw Hsp would confer protection during heat stress if added to chloroplasts not previously containing it. When the protein was added, the rate of electron transport at 47? C was 22% lower than a control sample at 25? C. When the protein was not added, the rate was at 47? C was 80% lower. These data, in conjunction with the previous experiments, proved that the chloroplast lmw Hsp increases the thermotolerance of photosynthetic electron transport (Heckathorn et al., 1998). Transgenic tomato lines overexpressing HsfA1a constituitively or a wild type control survived a one hour at 45? C heat shock, while a co-suppressed HsfA1a line (CS) did not survive the same heat stress (Baniwal et al., 2004). The third line analyzed was a wild type line (WT) used as a control. A heat shock treatment of one hour at 45? C was 9 applied to all three lines. No change in phenotype occurred in the HsfA1a-overexpressing and WT plants, but the CS plants died shortly after the treatment. A severe heat stress of one hour at 45? C prior to one hour at 55? C also killed WT plants, but HsfA1a- overexpressing plants survived. This indicated that HsfA1a is the main regulating component of thermotolerance in tomato plants. Although a single regulator Hsf has not been identified in Arabidopsis, the overall principles and conservation of Hsf families are similar in all plants (Heckathorn et al., 1998). In Arabidopsis, the role of Hsp 101 in thermotolerance has been investigated (Queitsch et al., 2000). A 15 minute heat shock at 45? C did not cause a phenotypic change in either control or Hsp 101 over-expressing plants. All plants looked as healthy as unstressed plants even after a five day period. After a 30 minute heat shock, all plants expressing Hsp101 remained as healthy as unstressed plants. However, empty vector transformed control plants that did not have an Hsp101 insert had some leaves that were bleached and withered. Most of the vector control plants died after a 45 minute treatment, while most of the constitutive plants survived. A 60 minute heat shock produced immediate phenotypic changes. Some leaves of the constitutive plants were also bleached. However, most of these plants survived and had returned to normal growth after 10 days, while all vector control plants had died. This data indicated that Hsp101 appeared to play a more pivotal role in the recovery of plants after heat stress than preventing stress related damage. Another important discovery was that changing the expression levels of Hsp101 did not affect normal plant growth, however, plants expressing high levels of Hsp101 showed a significant improvement in recovery after heat stress (Queitsch et al., 2000). 10 Chlorophyll Fluorescence Screening: Chlorophyll fluorescence data from plant leaves can determine the effectiveness of photosynthesis. When light strikes a chlorophyll molecule, electrons are boosted to an excited, higher energy state. They can not remain at this high-energy state. As a result, they fall back down to a lower energy level. The free energy can be used for photosynthesis, given off as heat, or emitted as red fluorescent light. The re-emitted light has a longer wavelength than the light that was absorbed. A chlorophyll fluorometer can be used to obtain quantitative chlorophyll fluorescence data of plants. The data is obtained by exposing a leaf to a defined wavelength of light and measuring how much light is re-emitted at longer wavelengths (Maxwell & Johnson, 2000). The defined wavelength of light emitted by the fluorometer has a corresponding ground state fluorescence value (F o ). A burst of intense bright light is used to induce maximum fluorescence (F m ). The initial electron acceptor of photosystem II (PSII) is reduced when this occurs. The fluorometer calculates the chlorophyll fluorescence value using the following formula: (F o -F m )/F m . The reported value for healthy leaves of any plant species is between 0.7 and 0.8. This value reflects the overall effectiveness of PSII. High fluorescence values indicate leaves capable of effective photosynthesis. If the value is low, PSII reaction centers have been damaged. Stress treatments, including heat stress, decrease the chlorophyll fluorescence values of leaves (Fracheboud, 2004). 11 III. METHODS AND MATERIALS Plant Material: Seeds of the control commercial cotton cultivar Deltapine DP 90 (DPL 90) were obtained from Dr. David Weaver, professor of Agronomy and Soils at Auburn University, Auburn, Alabama. This was chosen as the baseline commercial cotton cultivar used for this study because anecdotal reports from Alabama cotton growers indicated that despite the fact that this is an older cultivar, it is among the most heat and drought tolerant of cultivars available. Seeds of 1762 accessions of Gossypium hirsutum germplasm collection were obtained from A. E. Percival at the US National Cotton Germplasm Collection, Crop Germplasm Research Unit, Southern Crops Research Laboratory, Agricultural Research Service (ARS), United States Department of Agriculture (USDA), Soil and Crop Sciences Department, Texas A&M University, College Station, Texas. Plant Growth: All Gossypium accessions studied were planted individually in square, 10 cm, plastic pots containing PRO-MIX? soilless growth medium at the Auburn University Plant Science Research Center (PSRC). Plants were grown in lots of 50 to100 plants for 4 to 6 weeks under ambient conditions in a greenhouse. During this growth period, plants were sufficiently watered twice daily. They were fertilized once weekly with Peter?s ? brand 20-10-20 fertilizer in a 250 parts per million (ppm) solution applied through a Dosmatic ? with a 1:100 ratio. Two to four full expanded, healthy leaves were removed from each plant and placed in plastic sandwich 12 bags (Glad Storage ? ), which were not sealed. The collected leaves were subsequently placed in a growth chamber in the dark for chlorophyll fluorescence analysis. Chlorophyll Fluorescence Screening of Cotton Germplasm: Fluorescence readings were taken at room temperature within 15 minutes of collecting the leaves from greenhouse grown plants. All leaves were then placed in a 35? C growth chamber in the dark and allowed to equilibrate for one hour. Leaves were then transferred to a 45? C incubator in the dark. The leaves were removed after 30 minutes and fluorescence values were recorded using a chlorophyll fluorometer. Subsequently, the leaves were placed back into the 45? incubator and fluorescence readings were taken after 60 total minutes of incubation. Leaves were then transferred to a 55? C incubator and fluorescence readings were taken after 30 and 60 minutes in the same manner. All accessions that demonstrated an F v /F max ratio (ratio of variable to maximum fluorescence) at least 0.1 greater than DPL 90 were retained and reevaluated a second time to verify the results of the initial screening. Note that the value of 0.1 greater than DPL 90 was roughly three times the chlorophyll fluorescence shown by DPL 90 and was arbitrarily chosen as a preliminary value greater than that of DPL 90 and the subsequently determined mean of the tested accession. Subsequently, when the entire dataset was obtained this value appeared to have been a judicious choice since it was at least 1 standard deviation above the mean. Whole Plant Screening of Elite Accessions Identified Via Chlorophyll Fluorescence: Plants that exhibited superior chlorophyll fluorescence compared to the DPL 90 control (see above) in both initial stages of fluorescence screening were kept for a second whole plant thermotolerance evaluation. 44 accessions met these 13 criteria, but seed remained for only 22 of these accessions. The goal of this screening was to evaluate the validity of the chlorophyll fluorescence screening as an initial procedure of identifying thermotolerant cotton plants that performed above average. New groups of plants were grown as previously described above for each elite accession. Plants were then transferred to a Rheem Environmental Chamber (Puffer Hubbard), model number CEC38-15-G, and held at 25? C, with high humidity and light intensity. Plants were allowed to incubate under these conditions for three days. During this incubation time, plants were watered to soil saturation daily. After three days equilibration, heat stress was applied by raising the temperature in the growth chamber to 45? C. Pictures of the plants were taken before the application of heat stress, as well as each of the following days. The health and overall appearance of each plant was recorded daily to monitor the effect of the heat stress. Plants were well watered the first three days of heat stress. No water was given starting on Day 4 after the initiation of heat stress to also examine the compounding effect of drought stress and the heat tolerance of the accessions. The plants were monitored and photographed daily until most of the plants demonstrated symptoms of severe stress. Three levels of stress were established for this screening process. Level 1 stress was defined as a plant having at least one leaf that showed symptoms of stress. These symptoms include dark spots, limpness, discoloration including loss of green color, dryness, or a leaf that had fallen off the plant. Plants were said to display Level 2 stress when more than a few leaves showed stress symptoms mentioned previously. However, at least half of the leaves in a Level 2 stress plant were still green and fairly healthy. 14 Level 3 stress was reached when the majority of leaves showed significant symptoms of stress as previously described. 15 IV. RESULTS Chlorophyll Fluorescence Screening of Cotton Germplasm: The average initial fluorescence, reported as the F v /F max ratio, of the 1762 accessions at room temperature was 0.763 with a standard deviation of 0.043. The average ratio after one hour at 45? C was 0.680 with a standard deviation of 0.071. After one hour at 55? C, the average had dropped to 0.067 with a standard deviation of 0.057. Plants with a final reading of 0.1 and above (273 accessions) were kept and re-screened at a later date in the same manner. See Table 1 for a summary of the data for the primary screening, along with that of the DPL 90 control and the 273 re-screens. Figure 1 shows the distribution of the 1762 accessions and the DPL 90 control in the primary screening. After a second screening process on the 273 accessions that were kept, the average F v /F max ratio at room temperature was 0.766 with a standard deviation of 0.038. After one hour at 45? C, the average ratio was 0.677 with a standard deviation of 0.071. The ratio was 0.071 with a standard deviation of 0.063 after one hour at 55? C. There were 60 final (55? C, 60 minutes) fluorescence values greater than one standard deviation above the average final value for the entire second screening. These 60 fluorescence values represented 44 different accessions, with some accessions having multiple samples tested. The average final fluorescence value of these 60 accessions was 0.218 with a standard deviation of 0.089. The data for these 44 accessions is found in Table 2. The distribution of accessions (273 total) in the secondary screening is found in Figure 2. 16 Table 1.

Fourteen DPL 90 plants were used as the control in this screening. The 22 TX accessions had an average of 3.4 days until first signs of stress were evident (Level 1). The average for DPL 90 was two days until Level 1 stress had been reached. Level 2 stress was evident at 4.7 days in the TX accessions and 4.0 days in DPL 90 plants. 5 days marked Level 3 stress in DPL 90 plants, while 5.4 days marked this level in TX accessions. A summary of the whole plant screening of the elite 22 plants and DPL 90 is found in Table 3. This table also gives the fluorescence values in the primary and secondary screening for each of the 22 accessions. However, these accessions represent the half of the 44 accessions identified by chlorophyll fluorescence screening for which seed remained. The other 22 TX accessions that exhibited superior fluorescence ratios are as follows: TX 2, 256, 338, 462, 761, 786, 804, 816, 852, 1197, 1234, 1299, 1351, 1366, 1401, 1528, 1704, 1950, 2030, 2044, 2047, and 2326. Seven of the 22 accessions subjected to whole plant screening significantly outperformed DPL 90 in the whole plant screening. All seven of these accessions had greener, healthier leaves throughout the application of heat and drought stress. They also outlived the DPL 90 control plants under these conditions and survived until Day 7, when the stress treatment was stopped. Table 4 gives a summary of the whole plant screening and averages of the seven best accessions and DPL 90. The three levels of stress were considerably delayed in the seven TX accessions occurring at 3.7, 5.0 and 6.1 days, respectively. These stages were reached at 2, 4 and 5 days in the DPL 90 plants. 21 Figure 3 displays the average fluorescence values of the seven elite accessions, along with the DPL 90 control. The average fluorescence value after 60 minutes at 55? C for the DPL 90 control is approximately 0.05. This average value for the seven selected lines is approximately 0.25, five times greater than that of the control. Figure 4 adds the breakdown of the entire 44 accessions (60 fluorescence values) that excelled in the chlorophyll fluorescence screening. There were 31 accessions that had a final fluorescence value between one and two standard deviations above average. Nineteen accessions had a final fluorescence reading at least 2 standard deviations above average. Six of the 44 accessions appeared in both categories since there were multiple samples of some accessions. 22 Table 3.

DISCUSSION Upon examination of the 1762 TX accessions and the DPL 90 control (Figure 1), the two series of data have similar shapes up to a F v /F max value of 0.20. The series of accessions has a much longer tail beyond this value, indicating some accessions had much higher fluorescence ratios than those observed in DPL 90. The distribution of 273 accessions in the second screening resembles the distribution of the 1762 accessions in the primary screening. This distribution is shown in Figure 4. Figure 7 shows the distribution of the 44 accessions with a fluorescence value at least one standard deviation above average. It is evident that the curve is shifted to the right, indicating significantly higher fluorescence values than seen in the graphs of the entire primary and secondary screening distributions. All 44 accessions that had a final fluorescence value at least one standard deviation above the average through both rounds of screening were considered to be elite plants on the basis of chlorophyll fluorescence. However, we only had seed remaining for 22 of these accessions. These 22 different accessions were selected for the whole plant screening process discussed previously. Three of these plants had a final value at least two standard deviations above the average in both rounds of screening. Only two of the DPL 90 control plants had a final value significantly above average. The highest DPL 90 final value for a second round of screening was 0.195. This 27 value was substantially lower than some of the final values for wild accessions which were greater than 0.4. The F v /F max ratio reflects the efficiency of photosystem II during photosynthesis. The seven accessions which outperformed DPL 90 in all three rounds of screening had much higher F v /F max values. The average final value (55? C, 60 minutes) of these seven from the primary screening was 0.195. The average of the secondary screening was 0.230. DPL 90 had an average final fluorescence value of 0.055 in both rounds of chlorophyll fluorescence screening. This data is listed in Table 4. Also, Figure 5 shows the higher average values of the seven accessions throughout the sequential stress treatment. The higher values in the seven accessions suggest an improved performance of photosystem II, thus allowing photosynthesis to occur more effectively. The final seven accessions were selected not only for their superior chlorophyll fluorescence, but also for their performance and survival during the whole plant screening process. All seven looked healthier than DPL 90 throughout the stress treatment. The DPL 90 plants and other TX accessions had died by the end of the treatment on Day 7. The selected accessions all survived. However, the other 15 accessions that exhibited superior chlorophyll fluorescence did not survive the whole plant screening. 28 Figure 5.

CONCLUSION The seven accessions that exhibited superior chlorophyll fluorescence and survived the whole plant heat stress screening were clearly more thermotolerant and drought tolerant than DPL 90. However, not all plants that showed elite chlorophyll fluorescence performed well in the whole plant screening. It is apparent therefore that factors other than genotype can influence the heat-stress induced elite chlorophyll fluorescence phenotype, generating false positive results during chlorophyll fluorescence screening. This was also apparent in the first and second round of chlorophyll fluorescence screening. However, since seven of the 22 accessions selected by chlorophyll fluorescence screening outperformed the DPL 90 control, this method proved to be effective in identifying plants with improved thermotolerance. If future, research can identify the causes for the false positive fluorescence results, a correlation between heat-induced chlorophyll fluorescence and thermotolerance in Gossypium hirsutum may still emerge. The method developed in this research has already been successful in narrowing down a large quantity of plants to a select an elite few for further study. As a result of a possible correlation between chlorophyll fluorescence and thermotolerance, chlorophyll fluorescence screening could become a valuable approach to assessing thermotolerance in all plants. With the ever present issue of global warming, a method applicable to identifying and selecting thermotolerance in all species of plants could be of major ecological importance. 30 BIBLIOGRAPHY Baniwal SK, Bharti K, Chan KY, Fauth M, Ganguli A, Kotak S, Mishra SK, Nover L, Port M, Scharf KD, Tripp J, Weber C, Zielinski D and von Koskull-D?ring P. 2004.
