Chloroplasts/plastids are unique organelles found in plant cells and some algae and are responsible for performing essential functions such as photosynthesis. The plastid genome, consisting of circular and linear DNA molecules, is packaged and organized into specialized structures called nucleoids. The composition and dynamics of these nucleoids have been the subject of intense research, as they are critical for proper plastid functions and development. In this mini-review, recent advances in understanding the organization and regulation of plastid nucleoids are overviewed, with a focus on the various proteins and factors that regulate the shape and dynamics of nucleoids, including DNA-binding proteins and membrane anchorage proteins. The dynamic nature of nucleoid organization, which is influenced by a variety of developmental cues and the cell cycle, is also examined.
叶绿体/质体是存在于植物细胞和一些藻类中的独特细胞器，负责执行光合作用等基本功能。质体基因组由圆形和线性 DNA 分子组成，被包装并组织成称为类核的专门结构。这些类核的组成和动态一直是研究的热点，因为它们对质体的正常功能和发育至关重要。在这篇小型综述中，概述了对质体类核组织和调控的最新理解，重点介绍了调控类核形状和动态的各种蛋白质和因子，包括 DNA 结合蛋白和膜锚定蛋白。还研究了类核组织的动态性质，它受到各种发育线索和细胞周期的影响。
