Differential expression of genes in chickpea cultivars cv. BG-362 (A) and cv. BG- 1003 (B) exposed to drought stress at 0, 1, 3 and 7 days and recovery in the presence or absence of RA. The heat map has been generated based on the fold-change values in the treated sample when compared with its unstressed control sample. The colour scale for fold-change values is shown at the top.
