Fig. 8 — VqMYB154 can act in two pathways. First, VqMYB154 activates MBS elements in STS promoters to induce gene expression. Furthermore, VqMYB154 promotes the expression of the upstream PAL gene to provide more substrate for stilbene synthases, which biosynthesize more stilbenoids. The accumulation of stilbene phytoalexins enhances plant immunity. In addition, VqMYB154 stimulates ROS accumulation and upregulates the SA signaling-related genes AtICS1 and AtPR5. These defense-related genes and ROS accumulation also contribute to disease resistance
