细胞分裂素的生物合成、受体和信号转导的研究进展
Research Progress of the Biosynthesis, Receptor of Cytokinins and Cytokinin- Signal Transduction
摘要
Abstract
Cytokinins are essential regulators of numerous plant growth and development processes.It stimulates the formation and activity of shoot meristems, is able to establish sink tissues, retard leaf senescence, inhibit root growth and branching, and plays a role in seed germination and stress responses.During the past ten years, remarkable progress has been made to our understanding on the cytokinin biosynthesis, receptor and signal transduction, mainly using Arabidopsis thaliana as a model system.Biosynthetic pathways of cytokinins are mainly AMP pathway, ATP/ADP pathway.Arabidopsis thaliana possesses three cytokinin receptors: CRE1/WOL/AHK4, AHK2 and AHK3.Evidence has been provided that downstream signaling is transduced through a His-to-Asp phosphorelay involving phosphor transmitter and response regulator proteins, typical of two-component systems.关键词
