VOZ转录因子在植物开花调控及胁迫响应中的研究进展

Research Progress on VOZ Transcription Factors in Plant Flowering Regulation and Stress Response

在植物生长发育过程中,开花和应激反应是至关重要的事件。VOZ(vascular plant one-zinc finger)转录因子是存在于维管植物及苔藓植物中的一类植物转录因子。它于2004年在拟南芥(Arabidopsis thaliana)中被鉴定出来,并已被证明在成花和逆境胁迫响应中发挥着重要作用。本文在介绍VOZ转录因子的结构特征及VOZ基因成员在不同物种中的分布情况的基础上,总结了VOZ基因在不同物种中的表达模式及其在植物生长发育过程中发挥的功能,包括促进植物成花诱导和果实发育、提高植物对生物胁迫的耐受力、降低植物对非生物胁迫的抵抗能力以及调控种子萌发等方面,并阐述了VOZ转录因子在不同调控途径中与相关蛋白发生相互作用,从而发挥功能的分子机制。本文总结了VOZ转录因子发挥不同功能时的分子机制,旨在为植物开花和逆境胁迫领域的研究人员提供帮助,为进一步研究奠定理论基础。

During plant growth and development,flowering and stress responses are crucial events.Vascular plant one-zinc finger(VOZ)transcription factor is a type of plant transcription factor in vascular plant and moss plant.It was identified in Arabidopsis thaliana in 2004 and has been proven to play an important role in flowering and stress responses.This article introduced the structural characteristics of VOZ transcription factors and the distribution of VOZ gene members in different species.We also summarized the expression patterns of VOZ genes in different species and their functions in plant growth and development,including flower induction and fruit development promotion,improving plant tolerance to biotic stress,reducing plant resistance to abiotic stress,and regulating seed germination.In addition,we elucidated the molecular mechanisms by which VOZ transcription factors interact with related proteins in different regulatory pathways to exert their functions.This article summarized the molecular mechanisms by which VOZ transcription factors play different functions,aiming to provide assistance to researchers in the fields of plant flowering and stress and lay a theoretical foundation for further research.
