摘要/Abstract

摘要： 独脚金内酯是一类由类胡萝卜素衍生而来的新型植物生长调节因子,能够从抑制根部分生、诱导侧根形成、促进根毛伸长、介导根部与共生真菌和寄生植物信号通讯等多个方面调控植物生长发育。独角金内酯受体DWARF14（D14）起源于α/β水解酶,其信号转导机制不同于传统植物生长调节因子受体,它遵循新型的“底物-酶-活性分子-受体”识别规律,具有生成和感知生长调节因子活性分子的双重功能。综述了独脚金内酯受体D14结构及信号转导机制最新研究进展。

Abstract: Strigolactones（SL） is a new plant growth regulators derived from the carotenoid, which regulates the growth and development of plants, including inhibition of root branching, formation of lateral root, elongation lateral root and rhizospheric communication with symbiotic fungi and parasitic weeds. DWARF14 is the receptor of strigolactones that is originate from α/β hydrolase, whose signal transduction mechanism is different from classical growth regulators, and has the dual function of producing and sensing growth regulators active molecule. In this article, the newest research of the structure and molecular recognition mechanisms of D14 were summarized.

Key words: strigolactone, growth and development, DWARF14, CLIM, molecular recognition mechanisms
