Expression profile of genes encoding six selected DEPs in salt-stressed chickpea genotypes. Transcript level was determined by RT-PCR after normalization to the actin gene at three time-points: 1, 3, and 5 days of salt stress relative to the control using three individual replicates. Correlation of gene expression with corresponding protein abundance using Pearson’s correlation analyses was calculated (* p ≤ 0.05, ** p ≤ 0.01)
