Programmed Cell Death in Plants.
Programmed cell death (PCD) is a physiological cell death process involved in the selective elimination of unwanted cells (Ellis et al., 1991). In animals, these unwanted cells include those that have served temporary functions, such as tadpole tail cells at metamorphosis; cells that are overproduced, such as vertebrate neurons; cells that are unwanted or present in inappropriate positions, suc...
متن کاملDevelopmental programmed cell death in plants.
Mechanisms of plant developmental programmed cell death (PCD) have been intensively studied in recent years. Most plant developmental PCD is triggered by plant hormones, and the 'death signal' may be transduced by hormonal signaling pathways. Although there are some fundamental differences in the regulation of developmental PCD in various eukaryotes of different kingdoms, hormonal control and d...
متن کاملProgrammed death in bacteria.
Programmed cell death (PCD) in bacteria plays an important role in developmental processes, such as lysis of the mother cell during sporulation of Bacillus subtilis and lysis of vegetative cells in fruiting body formation of Myxococcus xanthus. The signal transduction pathway leading to autolysis of the mother cell includes the terminal sporulation sigma factor Esigma(K), which induces the synt...
متن کاملProgrammed cell death in bacteria and implications for antibiotic therapy.
It is now well appreciated that programmed cell death (PCD) plays critical roles in the life cycle of diverse bacterial species. It is an apparently paradoxical behavior as it does not benefit the cells undergoing PCD. However, growing evidence suggests that PCD can be 'altruistic': the dead cells may directly or indirectly benefit survivors through generation of public goods. This property pro...
متن کاملBacterial Programmed Cell Death and Multicellular Behavior in Bacteria
Traditionally, programmed cell death (PCD) is associated with eukaryotic multicellular organisms. However, recently, PCD systems have also been observed in bacteria. Here we review recent research on two kinds of genetic programs that promote bacterial cell death. The first is mediated by mazEF, a toxin-antitoxin module found in the chromosomes of many kinds of bacteria, and mainly studied in E...
