| 中文摘要:脱落酸（abscisic acid，ABA）是一种具有倍半萜烯结构的植物激素，在调控植物种子萌发、细胞生长、叶片脱落以及抵御生物与非生物逆境等重要生理过程中发挥着重要作用。该文在介绍ABA生物合成、分解代谢与信号转导的基础上，重点概括ABA信号途径在调控植物对植食性昆虫物理和化学防御中的作用及其机理，并指出今后的研究方向，为进一步揭示ABA信号途径在调控植物抗虫性的作用和机理提供参考。 |

| Abstract:Abscisic acid (ABA) is a plant hormone with sesquiterpene structure, which plays a vital role in regulating important physiological processes such as seed germination, cell growth, leaf shedding, and resistance to biotic and abiotic stresses. In this review, we summarize the recent advances in researches on the biosynthesis and catabolism of ABA and its signaling pathway. Moreover, we have reviewed the role of the ABA-signaling pathway in regulating physical and chemical defenses in plants against insect herbivores and the underlying mechanisms. In addition, we point out the future research directions in this area. We hope that this review will provide a basis for further revealing the role and mechanism of ABA signaling pathway in regulating plant resistance to insect herbivores. |
