Working model for TaGAPC1 in response to drought stress. The expression of TaWRKY40 is induced by drought stress, then, TaWRKY40 directly bind to the TaGAPC1 promoter to positively regulate the expression level of the TaGAPC1 gene by H2O2-dependent ABA signaling pathway, thereby increasing the tolerance of plant to drought stress. Among them, (+) represents promotion. Straight lines represent direct effects and dashed lines represent indirect effects
