植物卵形家族蛋白综述

Review of Plant OVATE Family Protein

卵形家族蛋白(OFPs)是一类植物特有的具有保守OVATE结构域的转录因子,其首先发现于番茄中,与果实形状有关。OFPs广泛分布于植物界,其调节植物生长和发育的功能,包括果实形状的改变、胚囊和花粉发育以及次级细胞壁的合成等。近年来,主要集中在拟南芥AtOFP1的研究上。染色质免疫沉淀试验表明AtOFP1直接调控AtGA20ox1表达,其还可能通过与不同类型的转录因子(包括KNOX和BELL类)相互作用。该研究总结了OVATE基因的发现,阐明了OFPs在调节植物生长和发育中的最新进展,并分析了其可能的调控机制,以期为植物中研究OFPs生物学功能提供借鉴。

OVATE family proteins（OFPs）is a class of plant-specific transcription factors with conserved OVATE domains.It is firstly found in tomato,and has influence on fruit shapes.OFPs are widely distributed in the plant kingdom,which regulate many aspects of plant growth and development,including changes in fruit shape,embryo sac and pollen development and secondary cell wall synthesis.In recent years,the researchers mainly focus on Arabidopsis thaliana AtOFP1.Chromatin immunoprecipitation assay（ChIP）show that AtOFP1 directly regulates AtGA20 ox1 expression.It may also interact with different types of transcription factors（including KNOX and BELL）.This study summarized the findings of OVATE to clarify the latest advances in OFPs in regulating plant growth and development.Finally,the possible regulation mechanism was analyzed,which could provide reference for studying the biological function of OFPs in plants.
