Abstract
Plant and animal organelles in cell death.
Highlights
Programmed cell death (PCD) is a finely regulated and genetically controlled process which plays crucial roles in various biological courses
The research of plant PCD will advance our understanding of how this process is regulated in plants, and provide insights into animal PCD pathways, mechanisms not existing in invertebrate model organisms
Our previous study showed that Arabidopsis mosaic death 1, in which a recessive mutation causes the deficiency in fatty acid biosynthesis in plastids, displays pleiotropic phenotypes of typical PCD features [6]
Summary
Programmed cell death (PCD) is a finely regulated and genetically controlled process which plays crucial roles in various biological courses. Similar morphological and biochemical features of PCD are observed between animal and plant, including cell shrinkage, chromatin condensation, nuclear fragmentation, cytochrome complex release, endonuclease release etc. Various caspase inhibitors which are originally used in animals can suppress PCD in plants, indicating conserved mechanisms between animal and plant.
