Model depicting the mechanisms of AtZAT6 involved in plant stress responses. Pathogen and abiotic stress could largely induce the expression of AtZAT6. First, AtZAT6 could bind to the TACAAT elements of the promoters of EDS1, PAD4, PR1/PR2/PR5, and CBF1/CBF2/CBF3, leading to accumulation of SA and up-regulation of these genes’ expression. Second, AtZAT6-overexpressing plants could result in higher ROS concentration. All of these results resulted in improved resistance to biotic and abiotic stress.
