植物是固着的，因此它们对环境挑战的反应与移动生物的反应不同。许多适应都涉及生长反应，因此，生长调节是植物生存和适应最关键的生物学过程之一。植物特有的teosinte分支1，CycloidEA，PCF1(Tcp)转录因子家族参与植物从发芽到死亡的整个发育过程，即从种子萌发到营养发育，直到花和果实的形成。在多种植物中，包括兰花、西红柿、豌豆、杨树、棉花、水稻和模式植物拟南芥，TCP转录因子具有进化保守的调节作用。早期对TCPs的研究主要集中在TCPs通过细胞周期在不同器官发育中的调节功能。后来的研究发现，TCP转录因子不是静态的发育调节因子，而是关键的生长调节因子，它将各种内源和环境信号转化为最适合确保植物健康的生长反应。本文将从两个方面对TCPs的研究进行综述：TCPs的发现及其在整个植物界中进化保守作用的阐明，以及TCPs在发育过程中对内源信号(生物钟、植物激素)和环境信号(病原体、光、营养物质)的响应。
Plants are sessile and as such their reactions to environmental challenges differ from those of mobile organisms. Many adaptions involve growth responses and hence, growth regulation is one of the most crucial biological processes for plant survival and fitness. The plant-specific TEOSINTE BRANCHED 1, CYCLOIDEA, PCF1 (TCP) transcription factor family is involved in plant development from cradle to grave, i.e., from seed germination throughout vegetative development until the formation of flowers and fruits. TCP transcription factors have an evolutionary conserved role as regulators in a variety of plant species, including orchids, tomatoes, peas, poplar, cotton, rice and the model plant Arabidopsis. Early TCP research focused on the regulatory functions of TCPs in the development of diverse organs via the cell cycle. Later research uncovered that TCP transcription factors are not static developmental regulators but crucial growth regulators that translate diverse endogenous and environmental signals into growth responses best fitted to ensure plant fitness and health. I will recapitulate the research on TCPs in this review focusing on two topics: the discovery of TCPs and the elucidation of their evolutionarily conserved roles across the plant kingdom, and the variety of signals, both endogenous (circadian clock, plant hormones) and environmental (pathogens, light, nutrients), TCPs respond to in the course of their developmental roles.
