Editorial: Advances in Plastid Biology and Its Applications
Advances in Plastid Biology and Its Applications Plastids originated from endosymbiosis around 1.5 billion years ago. They have been extensively studied to understand photosynthesis and other metabolic functions and to express foreign proteins, and knowledge about plastids has greatly increased. However, there are many aspects of plastid biology that remain unclear, and there have been difficul...
متن کاملThe molecular biology of plastid division in higher plants.
Plastids are essential plant organelles vital for life on earth, responsible not only for photosynthesis but for many fundamental intermediary metabolic reactions. Plastids are not formed de novo but arise by binary fission from pre-existing plastids, and plastid division therefore represents an important process for the maintenance of appropriate plastid populations in plant cells. Plastid div...
متن کاملPlastid Origins
The evolution of oxygenic photosynthesis in the ancestors of present-day cyanobacteria transformed the biosphere of our planet (Blankenship 1994; ReyesPrieto et al. 2007). This landmark event was also an essential prerequisite for the evolution of photosynthetic eukaryotes. Plastids, or chloroplasts, are the lightgathering organelles of algae and plants whose origin can be traced back to cyanob...
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 کاملDoes the Mode of Plastid Inheritance Influence Plastid Genome Architecture?
Plastid genomes show an impressive array of sizes and compactnesses, but the forces responsible for this variation are unknown. It has been argued that species with small effective genetic population sizes are less efficient at purging excess DNA from their genomes than those with large effective population sizes. If true, one may expect the primary mode of plastid inheritance to influence plas...
