摘要
质体是植物细胞合成代谢中最主要的细胞器,在植物生长发育过程中的发挥重要作用。原纤蛋白(FBN)是一种主要由核基因编码的质体脂类结合蛋白,是植物质体蛋白中的一个重要家族,广泛存在于植物的质体中。研究证明, FBN能够维持质体的稳定性,并能与质体中的相关蛋白相互作用从而维持植物的正常生长发育。FBN能够响应脱落酸的诱导,并影响茉莉酸的生物合成,在植物激素信号调控过程中发挥重要作用。在植物代谢方面, FBN参与调节植物的光合作用、抗氧化物质和脂质合成等过程。FBN基因能够提高植物对高温、低温、干旱和盐胁迫等非生物逆境和对病原菌等生物胁迫的抵抗能力。本文综述了FBN家族的亚细胞定位与互作及其在植物的生长发育、激素调节、代谢调控和逆境应答方面的研究进展,并展望了FBN今后的重点研究方向。
Plastids are the primary organelles in the synthetic metabolism of plant cells,playing a pivotal role in the growth and developmental processes of plants.Fibrillin(FBN)is a type of plastid lipid binding protein mainly encoded by nuclear genes.FBN is an important family of plant plastid proteins and widely exists in plant plastids.It has been proved that FBN protein can maintain the stability of plastids and interact with related proteins in plastids to maintain normal plant growth and development.FBN can respond to the induction of abscisic acid and affect the biosynthesis of jasmonic acid,playing an important role in the regulation of plant hormone signaling.In terms of plant metabolism,FBN is involved in regulating processes such as photosynthesis,antioxidant substances and lipid synthesis in plants.The FBN gene can enhance plants'resistance to abiotic stress such as high temperature,low temperature,drought and salt stress,as well as biotic stress such as pathogens.This article reviews the subcellular localization and interactions of the FBN family,as well as its research progress in plant growth and development,hormone regulation,metabolic regulation and stress response.It also looks forward to the future research directions of FBN.
