Expression studies of transcription factors under moisture stress in Cotton (Gossypium hirsutum L.)

Published on

The process of plant adaptation to the environmental
stresses is controlled by orchestration of complex
molecular networks regulated by transcription factor (TF)
genes. In the present study, JK-4(G11), CPD-433(G15) and
5433A2A03 N83(G16) recorded higher relative water
content under moisture stress condition as compared
to other genotypes with higher level of proline content
indicating their role in drought tolerance. Further,
expression analysis of TF genes from cotton
(GhWRKY19, GhLIM, GhNAC, GhGeBP, GhWRKY70 and
GhC2H2) through qRT-PCR in 27 different cotton
genotypes showed differential expression under stress
condition indicating their role in stress tolerance.

Keywords: Abiotic stresses, cotton, moisture stress, qRT-PCR, TF genes.
