Virus-Induced Gene Silencing of SlWRKY79 Attenuates Salt Tolerance in Tomato Plants

Previous studies have shown that WRKY transcription factors play important roles in abiotic stress responses. Thus, virus-induced gene silencing (VIGS) was used to identify the function of SlWRKY79 salt tolerance tomato plants by downregulating expression gene. Under same treatment conditions, SlWRKY79-silenced showed faster stem wilting and more severe leaf shrinkage than control plants, bending degree also greater plants. Physiological analyses considerably higher levels hydrogen peroxide (H2O2), superoxide anion (O2?), abscisic acid (ABA) accumulated leaves those controls after treatment. Taken together, our results suggested plays a positive regulatory role
