Plant immune inducer ZNC promotes rutin accumulation and enhances resistance to Botrytis cinerea in tomato

Abstract Gray mold is a destructive disease caused by Botrytis cinerea , pervasive plant pathogen, which poses threat to both tomato growth and postharvest storage. The utilization of induced resistance presents potential strategy for combating pathogenic attacks. ZNC (zhinengcong), an extract derived from the endophytic fungus Paecilomyces variotii has been discovered play vital role in preventing diverse forms bacterial infections. Nevertheless, precise mechanism behind its ability enhance fungi remains unclear. In this study, we found that exogenous spraying could significantly improve plants B. . results metabolomic analysis high-performance liquid chromatography (HPLC) demonstrated responded treatment accumulating high levels rutin. Additional transcriptome uncovered rutin enhances possible initiating generation reactive oxygen species (ROS) phosphorylation mitogen-activated protein kinases (MPKs) related genes expression during initial phase invasion addition, also might activate immunity eliciting ethylene (ET) jasmonic acid (JA)-mediated pathways. Therefore, immune inducer bright application prospects value control gray mold. Graphical
