Chloroplast division is driven by a ring containing FtsZ1 and FtsZ2 proteins, which originated from bacterial FtsZ, a tubulin-like protein; however, mechanistic details of the chloroplast FtsZ ...

近日，上海交通大学农业与生物学院陈诚课题组在Cell Reports发表了题为“Adaptive Evolution of Chloroplast Division Mechanisms during Plant Terrestrialization”的研究论文，揭示了植物叶绿体分裂机制中少数起源于真核宿主细胞的分裂基因更多地参与到帮助植物适应登陆后复杂、多变环境生物学过程的适应性演化机制。

Figure 1: Sequence of events in chloroplast division (from top left to bottom right). An FtsZ ring forms inside the chloroplast double membrane at the division site. A plastid division (PD) ring forms ...

The chloroplasts in this mutant possessed only a single nucleoid, and showed unequal segregation during chloroplast division. A homologous moc1 gene was then found in a land plant commonly used ...

Chloroplasts, like their cyanobacterium ancestors, proliferate through division. Cyanobacteria have a peptidoglycan layer component in their cell walls, but this layer has never been observed in ...

When Katherine Osteryoung started her postdoctoral fellowship in Elizabeth Vierling's laboratory at the University of Arizona, Tucson, she wanted to work on heat shock proteins, which cells make in ...
