This thesis entitled, “Subterranean termite, Reticulitermes flavipes, colony behavior and population dynamic changes under conditions of exposure to chitin synthesis inhibitor bait”, explores key components involved in ...
Management of Rotylenchulus reniformis and Meloidogyne incognita on Gossypium hirsutum in Alabama and the economic impact of additional fertilizer and nematicide applications
(2021-07-13)
The reniform nematode, Rotylenchulus reniformis and the southern root-knot nematode Meloidogyne incognita are some of the most damaging plant parasitic nematodes on upland cotton in the United States. Management strategies ...
Probing the Adaptation Strategies in the Genus Xanthomonas
(2021-07-21)
Bacterial species belonging to the genus Xanthomonas can infect and cause severe diseases in a wide range of host plants including many economically important crops throughout the world. While the majority of studies ...
A valine to leucine mutation in hypomorphic Wolbachia CidB reduces both deubiquitylation and cytoplasmic incompatibility
(2021-07-23)
Cytoplasmic incompatibility (CI) remains one of the most highly researched and applied phenotype conferred by the bacterium, Wolbachia on the host organisms it infects. For programs that rely on the CI phenomenon, the ...

(2021-08-02)
Fusarium oxysporum f. sp vasinfectum (Fov), the causal agent of Fusarium wilt of cotton (Gossypiym species), is causing a devastating decline in worldwide cotton production. Although many factors associated with pathogenicity ...
Natural competence distribution among Xylella fastidiosa strains and construction of a mutant library for RB-TnSeq
(2021-12-01)
The plant pathogen Xylella fastidiosa is a gram-negative, fastidious, xylem-limited, vector-transmitted bacterium, causing severe diseases on many economically important plants such as grapes, citrus, coffee, olive and ...
Fitness strategies of fastidious prokaryotes
(2021-12-01)
Fastidious prokaryotes are slow-growing bacteria that either require specific media to grow or are not able to grow axenically. ‘Candidatus Liberibacter asiaticus’ (CLas) and Xylella fastidiosa are important fastidious ...
