Abstract

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.
