Fig. 1From: Genome-wide transcriptomic analysis of a desert willow, Salix psammophila, reveals the function of hub genes SpMDP1 and SpWRKY33 in drought tolerancePhysiological responses to drought stress in the roots of S. psammophila. The experiments were performed in three biological replicates and three technical replicates. The data were analyzed with Student’s t test. * and ** represent significance of P < 0.05 and P < 0.01 of three time points (6, 24 and 96 h) compared with the control (0 h), respectivelyBack to article page
