Peroxisomes are highly dynamic subcellular organelles that undergo proliferation in response to a variety of environmental stimuli. The past few years have witnessed the identification and characterization of several key classes of proteins required for peroxisome division and proliferation in Arabidopsis. These include the PEROXIN11 (PEX11) family, the dynamin-related proteins (DRPs), and the FISSION1 (FIS1) proteins, some of which are shared by the division machineries of peroxisomes and other organelles. Recent studies have also uncovered a role for the photoreceptor phyA and the bZIP transcription factor HY5 homolog (HYH) in regulating light-induced peroxisome proliferation in Arabidopsis. In this review we attempt to summarize the current state of our knowledge of peroxisome division/proliferation and their regulation in plants.
过氧化物酶体是高度动态的亚细胞细胞器，它们会响应各种环境刺激而增殖。在过去的几年中，已经鉴定和描述了几种关键的蛋白质类群，这些蛋白质对于拟南芥中过氧化物酶体的分裂和增殖是必需的。这些蛋白质包括 PEROXIN11（PEX11）家族、与动力蛋白相关的蛋白质（DRPs）和 FISSION1（FIS1）蛋白，其中一些蛋白质是过氧化物酶体和其他细胞器的分裂机制所共有的。最近的研究还揭示了光受体 phyA 和 bZIP 转录因子 HY5 同源物（HYH）在调节拟南芥中光诱导的过氧化物酶体增殖中的作用。在这篇综述中，我们试图总结目前我们对植物中过氧化物酶体分裂/增殖及其调控的认识。
