摘　　要：光敏色素互作因子(Phytochrome-interacting factor,PIF)属于碱性螺旋—环—螺旋(Basic Helix–Loop–Helix,b HLH)类转录因子,参与植物多个生物进程,作为胞内信号调节"枢纽",不但参与调控植物的生长发育,且在植物抵御逆境胁迫过程中发挥重要作用。本文中主要阐述PIF集成复杂的网络调控植物对低温、高温、荫蔽、干旱等非生物胁迫的应答反应,以及PIF通过植物激素信号途径介导植物对病虫害等生物胁迫的防御机制,为研究PIF在逆境胁迫中的作用,提高作物抗性和品质等提供参考。Belonging to b HLH( Basic Helix – Loop – Helix) transcriptional factor family,phytochrome-interaction factors(PIFs) are involved in many biological processes of plants. As the"hub"of intracellular signal regulation,PIFs not only participate in the regulation of plant growth and development,but also plays an important role in the process of plant resistance to stress. The main points of this paper are:PIFs integrate complex networks to regulate plant responses to abiotic stresses such as temperature,shading stress and drought,meanwhile,they mediate the defense of plants against biotic stresses such as pests and diseases through plant hormone signaling pathway. Our research could provide reference for further study of PIFs.
