转录因子在植物响应UV-B辐射中的调控作用
The Regulatory Roles of the Transcription Factors in Plant's Response to UV-B Radiation
摘要
Abstract
UV-B,as an inherent constituent of sunlight,exerts a crucial influence on the growth and development of plants.Recent studies showed that UV-B is not merely an environmental stressor,but also a functional signal molecule that is able to promote plant growth under moderate radiation level.The protein UVR8,as a unique photoreceptor specific to UV-B,plays an irreplaceable role in the plant's response to UV-B,whose functions are regulated by both upstream and downstream transcription factors.At present,a variety of transcription factors such as BBXs,WRKYs,MYBs,and PIFs have been reported to be involved in UV-B regulated processes like hypocotyl elongation,primary root length,leaf size and shape,flowering cycle,and anthocyanin synthesis.This article reviews the molecular mechanisms of UVR8 in the UV-B signaling pathway and summarizes the regulatory mechanisms of the transcription factors during the UV-B radiation process,to provide reference for relevant research.关键词
