摘　　要：Dear Editor,Tomato systemin(TomSys),the first discovered plant peptide hormone,can initiate systemic mobile signals to stimulate an immune response in both wounded and intact leaves(Pearce et al.,1991).For decades,biologists have been striving to uncover the mechanisms of TomSys function,but detailed information on the TomSys-regulated systemic defense process remains limited to date.The specific roles of three potential transmissible signaling components,ProSys mRNA,TomSys,and jasmonic acid(JA),in activation of systemic defense responses still need to be clarified(Zhang et al.,2020).
