中文摘要:

      茉莉酸甲酯(methyl jasmonate, MeJA)是一种广泛存在于植物中的天然植物激素, 参与植物的许多代谢过程包括生长、发育、成熟、衰老、抵御生物和非生物胁迫等。由病原真菌侵染引起的果蔬采后病害是导致果蔬贮藏和运输过程中品质劣变和腐烂的原因之一, 不仅对生产者和消费者造成巨大经济损失, 还会在组织体内产生危害人体健康的有毒次生代谢产物。因此, 开发绿色安全的果蔬采后病害控制技术具有重要意义。本文总结了采前和采后MeJA单独或与其他物理、生物方法复合处理对果蔬采后主要真菌性病害的控制作用, 并从活性氧代谢、病程相关蛋白的积累、苯丙烷代谢、多胺代谢、能量代谢、细胞壁物质代谢、转录调控等方面详细阐述了其诱导抗性机制, 以期为MeJA广泛用于控制果蔬采后病害提供实践参考和理论依据。

英文摘要:

      Methyl jasmonate (MeJA) is a natural plant hormone widely existing in plants, which involves in many metabolism processes of plant including growth, development, maturity, senescence, responding to biotic and abiotic stresses. Postharvest disease of fruits and vegetables caused by pathogenic fungus infection is one of the causes of quality deterioration and decay during storage and transportation, which not only results in huge economic losses for producers and consumers, but also produces toxic secondary metabolites in tissues that harmful to human health. Therefore, it is of great significance to develop green and safe technology to control postharvest disease of fruits and vegetables. This paper reviewed the effects of pre-harvest and postharvest MeJA alone or combined with other physical and biological methods treatments on the control of major postharvest fungal diseases of fruits and vegetables in detail. The mechanisms involved in its action including reactive oxygen species metabolism, pathogenesis-related protein accumulation, phenylpropanoid pathway, polyamine metabolism, energy metabolism, cell wall metabolism and transcriptional regulation were also represented. All these findings could provide practice reference and theoretical basis for postharvest decay control of fruits and vegetables.
