摘要:

番茄是一种世界性种植的重要蔬菜作物,在种植过程中易受病虫害的影响,造成减产。表皮毛是番茄表面第一道关键的屏障,可增强番茄对生物和非生物胁迫的适应性。为了进一步研究表皮毛在番茄抗逆中的作用机理,本文归纳了番茄表皮毛内含物的种类及其分子调控机制,重点总结了JA信号途径中的核心转录因子MYC1和MYC2对番茄表皮毛萜类化合物合成调控的分子机制,并分析了当前表皮毛研究存在的问题,展望了表皮毛未来的研究方向。

Abstract:

Tomato is an important vegetable widely grown worldwide, and it is susceptible to pests and diseases, resulting in the reduction of yield. Trichome is a crucial barrier covering the epidermis of tomato, which can enhance the adaptability of tomato to biotic and abiotic stresses. In order to further study the functional mechanism of trichomes in tomato stress resistance, the types of tomato trichome inclusions and molecular regulation mechanism were summarized in this review, and the molecular mechanism of the terpenoids’ synthesis regulation in tomato trichomes by the core transcription factor MYC1 and MYC2 in JA signaling pathway was concluded. The problems existing in the current trichome research were analyzed, and the future research direction of trichome was discussed.

Key words: JA signaling, regulating mechanism, tomato trichome, terpenoids, SlMYC1/2, transcription factor
