Quantitative Real-Time PCR analysis of the five drought inducible proteins a, and correlation of qRT-PCR (log2 scale) and protein fold change b. Barley GAPDH and ACTIN were used as the reference genes. Data plotted are the mean ratio of gene/protein expression on the four sampling dates (SMC10, SMC4, R1 and R2) in drought treatment over those in the control in the XZ5, XZ54 and ZAU3 on a log2 scale (R 2 = 0.8072, P < 0.01). SMC10 and SMC4, and R1 and R2 represent soil moisture content at 10 % and at 4 %, respectively, and after 2 and 5 days of recovery following drought stress
