摘要: 转录因子TCP(TEOSINTE BRANCHED1,CYCLOIDEA,PROLIFERATING CELL FACTORS)家族具有bHLH(basic-Helix-Loop-Helix)二级结构域,根据结合位点碱基序列不同,将TCP家族分为两大类:Ι类(GGNCCCAC)和Ⅱ类(GTGGNCC)。转录因子TCP4是植物特有的转录因子Ⅱ类TCP家族成员之一,调控植物的生长发育,影响多种植物激素的合成,参与植物抗逆调节。本研究综述了转录因子TCP4与植物其他转录因子家族相互作用参与植物种子萌发、表皮毛分化、叶片形态、开花等重要植物生长发育过程,以此适应外界不断变化的生长环境。植物在生长发育过程中会遇到各种不利环境,从而对其造成逆境胁迫。在非生物胁迫下转录因子TCP4与功能基因的顺式作用元件结合调控其表达,调控植物激素的合成,从而参与植物抗逆。在植物发育过程中TCP4还具有时空限制的表达模式,这些表达模式提高了TCP4在局部触发或拮抗激素信号传导的可能性。为转录因子TCP4如何调控植物生长发育和精准的参与植物激素合成提供参考依据和理论基础,对植物生长调节和逆境下优良品种的选育有重要指导意义。

Abstract: The transcription factor TCP (TEOSINTE BRANCHED1, CYCLOIDEA, and PCF) family has bHLH (basic-Helix-Loop-Helix) secondary domain. According to the different base sequences of binding sites, the TCP family was divided into two categories:Ι Class (GGNCCCAC) and II class (GTGGNCC). The transcription factor TCP4 is one of the II class members of plant-specific transcription factors. TCP4 regulates the growth and development of plants, affects the synthesis of a variety of plant hormones, and participates in the regulation of plant resistance. This article reviews the involvement of transcription factor TCP4 interacts with other plant transcription factor families in plant seed germination, epidermal hair differentiation, leaf morphology, flowering and other important plant growth and development processes.So plants adapt to the changing growth environment of the outside world. Plants will encounter various environments in the process of growth and development, resulting in stress. Under abiotic stress, transcription factor TCP4 combines with cis acting elements of functional genes to regulate its expression and regulate the synthesis of plant hormones, so as to participate in plant stress resistance. During plant development, TCP4 also has spatio-temporal limited expression patterns, which improve the possibility of TCP4 triggering or antagonizing hormone signal transduction locally. It provides a reference and theoretical basis for how transcription factor TCP4 regulates plant growth and development and accurately participates in plant hormone synthesis, and has important guiding significance for plant growth regulation and breeding of excellent varieties under stress.

Key words: Transcription factor TCP4, Growth and development, Stress resistance regulation, Plant hormones
