Expression patterns of TaPYL4 in roots and aerial tissues under drought stress condition. A transcripts of TaPYL4 in tissues upon modified external PEG concentrations; B transcripts of TaPYL4 under drought as well as normal recovery treatments. In B 0 h, time point prior to drought treatment (control); 1 h, 3 h, 9 h, and 27 h, times following drought condition; R1 h, R3 h, R9 h, and R 27 h, times following recovery growth condition. Values shown are averages derived from triplicate results and error bars indicate standard errors with symbol * to represent statistically significant compared with control (without PEG in A and 0 h in B) (P < 0.05). Expression levels shown are ratios of the transcripts between target gene and the reference Tatubulin
