摘　　要：中间纤维(IFs)是一种表观直径在10 nm左右,介于微管(25 nm)和微丝(5~7 nm)之间的细胞骨架蛋白纤维,目前已发现其能在不同的组织中形成多种类型的蛋白,并且在生物体发育过程中呈组织特异性表达。在动物细胞中,IFs提供了机械稳定性,并维持了细胞和组织的形态,许多IF蛋白编码基因已经在动物中鉴定出来。在植物细胞中,最早的研究始于20世纪80年代,最初从一些免疫学方面的证据证明了植物中存在中间纤维蛋白。近些年来,在植物中陆续发现了许多中间纤维蛋白,与动物中的功能相同。中间纤维可通过调控核纤层-染色质网络以调控基因的表达。该文综述了植物细胞中间纤维的研究进展,对细胞骨架功能探究具有重要意义。Intermediate filaments(IFs)are cytoskeletal protein filaments with an apparent diameter of around 10 nm,intermediate between microtubules(25 nm)and microfilaments(5-7 nm).IFs have been found to form multiple types of proteins in different tissues and are tissue-specifically expressed during organismal development.In animal cells,IFs maintain cell and tissue morphology by providing mechanical stability,and many different genes encoding IF proteins have been identified.In the 1980s,intermediate filaments in plant cells were initially demonstrated by some immunological evidences.In recent years,a number of IF proteins have been discovered in plants that perform the same functions as animal IF.IF proteins can regulate gene expression by modulating the lamin-chromatin network.In this paper,we review the progress and results of the study of IF in plant cells,and a comprehensive and in-depth study of IF proteins in plants will be of great significance for the exploration of cytoskeletal functions.
