褪黑素诱导果实采后抗病性研究进展

Advances in Research on Postharvest Disease Resistance Induced by Melatonin

褪黑素作为一种微量、高效的天然植物信号分子,在植物生长发育、非生物胁迫、采后保鲜等方面已被广泛报道。近年来研究发现褪黑素在诱导果实抗病性方面发挥着积极作用。本文阐述了褪黑素在离体与果实中对病原菌的影响,重点总结了褪黑素诱导果实抗侵染性病害机制,初步揭示了褪黑素通过与植物各信号转导途径组成的调控网络来介导果实抗病反应。同时展望了未来研究方向,为之后深入研究褪黑素的抗病机理提供理论参考。

Melatonin,a trace efficient natural plant signaling molecule,has been widely reported in plant growth and development,abiotic stress,and postharvest preservation and other aspects.In recent years,melatonin has been found to play a positive role in inducing disease resistance in fruits.This paper describes the effect of melatonin on pathogens in vitro and in infected fruits,with a focus on the mechanism by which melatonin induces fruit resistance to invasive diseases.Furthermore,this paper reveals that melatonin and plant signal transduction pathways constitute a regulation network to mediate disease resistance responses in fruits.We conclude this paper with an outlook on future research directions in order to provide a theoretical reference for further research on the mechanism by which melatonin induces disease resistance.
