Root transcriptome profiling of contrasting wheat genotypes provides an insight to their adaptive strategies to water deficit.

ABSTRACT: Water deficit limits plant growth and productivity in wheat. The effect of water deficit varies considerably in the contrasting genotypes. This study attempted comparative transcriptome profiling of the tolerant (Abura) and susceptible (AUS12671) genotypes under PEG-simulated water stress via genome-wide RNA-seq technology to understand the dynamics of tolerance mechanism. Morphological and physiological analyses indicated that the tolerant genotype Abura had a higher root growth and net photosynthesis, which accounted for its higher root biomass than AUS12671 under stress. Transcriptomic analysis revealed a total of 924 differentially expressed genes (DEGs) that were unique in the contrasting genotypes under stress across time points. The susceptible genotype AUS12671 had slightly more ab
