Update on Plastid Division Mechanism of Plastid Division: From a Bacterium to an Organelle
Chloroplasts arose more than 1 billion years ago, when a free-living cyanobacterium became an endosymbiont in a eukaryotic host cell. Several lines of evidence indicate that all chloroplasts and their nonphotosynthetic relatives (plastids) are directly or indirectly derived from a single endosymbiotic event (Reyes-Prieto et al., 2007; Gould et al., 2008; Archibald, 2009; Fig. 1). The original e...
متن کاملPlastid division
BACKGROUND AND AIMS Plastids undergo a process of binary fission in order to replicate. Plastid replication is required at two distinct stages of plant growth: during cell division to ensure correct plastid segregation, and during cell expansion and development to generate large populations of functional plastids, as in leaf mesophyll cells. This review considers some of the recent advances in ...

متن کاملPlastid division is driven by a complex mechanism that involves differential transition of the bacterial and eukaryotic division rings.
During plastid division, two structures have been detected at the division site in separate analyses. The plastid-dividing ring can be detected by transmission electron microscopy as two (or three) electron-dense rings: an outer ring on the cytosolic face of the outer envelope, occasionally a middle ring in the intermembrane space, and an inner ring on the stromal face of the inner envelope. Th...
متن کاملPlastid division. The origin of replication
The fact that chlorophyll-containing chloroplasts are remarkably abundant organelles in plants is obvious to anyone contemplating the verdant green expanses of most global ecosystems. For those who have viewed leaf mesophyll cells by peering down a microscope, it is also apparent that these specialized cells can contain large numbers of chloroplasts—up to 200 in some cells—and that chloroplasts...
