Genome Wide Association Study (GWAS) on Root-Knot Nematode Resistance in Cultivated Peanut
(2019-07-16)
The peanut root-knot nematode, Meloidogyne arenaria, is one of the major soil-borne pests for peanut (Arachis hypogaea L.). It causes economic losses in the production of peanut in the southeastern region, especially in ...
Genome-wide association studies for columnaris resistance and morphology in hybrid catfish
(2016-03-03)
Catfish is the primary aquaculture species in the United States. Recently, the catfish industry in the USA has encountered unprecedented challenges due to increasing feed and energy costs, devastating diseases, and severe ...
Genome-Wide Associations Identifying Marker-Trait-Associations for Root Morphology and Photosynthetic Related Traits in a Soybean (Glycine max) Diversity Panel
(2023-04-26)
Soybean is a staple crop for the food, feed, and fuel industries because of its unique oil and protein composition. It is the second most produced crop globally, with average acres planted and harvest yield increasing ...
Genome-wide Characterization of Heat Shock Proteins in Channel Catfish (Ictalurus punctatus) and Determination of Their Involvement in Diseases
(2014-11-24)
Heat shock proteins (HSPs) consist of a large group of chaperones whose expression is induced by a number of stresses such as exposures to high temperature, hypoxia and infection.
In this study, I identified a total of ...
Genome-wide comparative analysis of channel catfish (Ictalurus punctatus)
(2013-04-22)
Comparative map is a powerful tool to transfer the genomic information from well-studied model species to non-model species whose genomic resources are limited. Channel catfish is a primary aquaculture species in United ...
Genome-wide DNA Methylation and Transcriptome-wide Responses to a Bout of Higher- Versus Lower-load Resistance Training in Previously Trained Men
(2022-07-27)
We sought to determine how genome-wide DNA methylation and transcriptome responses in skeletal muscle differed between one bout of lower-load versus higher-load resistance exercise. Previously trained college-aged males ...
Genomic Analyses of Hybridization and Speciation in Macaques
(2023-05-01)
Speciation, the origin of species, is a process fundamental to producing the current diversity of life, and has been a central subject of evolutionary biology for the past century. Hybridization, the mating of individuals ...
Genomic and transcriptomic analysis of genes involved in disease resistance against enteric septicemia of catfish (ESC) in catfish
(2018-11-08)
Catfish is the leading aquaculture species in the United States, accounting for over 50% of all U.S. aquaculture production. In recent years, catfish industry has been facing numerous challenges, including increased costs ...
Genomic Approaches to Characterization of the Innate Immune Response of Catfish to Bacterial Infection
(2007-05-15)
Genetic selection for disease resistance encoded in the genomes of blue catfish and channel catfish continues to hold the greatest potential for long-term solutions to aquaculture-based disease outbreaks. Progress towards ...
Genomic Characterization of Expressed Sequence Tags and Gene Expression Profiling of the Three Life-Cycle Stages of Ichthyophthirius multifiliis
(2010-05-05)
The ciliate protozoan Ichthyophthirius multifiliis (Ich) is an important parasite of freshwater fish that causes 'white spot’ disease. Ich is a major contributor of fish mortalities and economic loss to both the ornamental ...
