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 کاملAbiotic Stress-Induced Programmed Cell Death in Plants: A Phytaspase Connection
The plants in the course of ontogenesis are frequently exposed to various unfavourable environmental stress factors (such as high and low temperatures, heavy metals, salt and anaerobic stress, biotic stresses, etc.). If extreme, these stress factors can bring about damage of agricultural crops and wild flora causing considerable environmental and economic losses worldwide. In the course of evol...
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 cell death: a way of life for plants.
Cell death in higher plants has been widely observed in predictable patterns throughout development and in response to pathogenic infection. Genetic, biochemical, and morphological evidence suggests that these cell deaths occur as active processes and can be defined formally as examples of programmed cell death (PCD). Intriguingly, plants have at least two types of PCD, an observation that is a...
متن کاملA Conserved Core of Programmed Cell Death Indicator Genes Discriminates Developmentally and Environmentally Induced Programmed Cell Death in Plants.
A plethora of diverse programmed cell death (PCD) processes has been described in living organisms. In animals and plants, different forms of PCD play crucial roles in development, immunity, and responses to the environment. While the molecular control of some animal PCD forms such as apoptosis is known in great detail, we still know comparatively little about the regulation of the diverse type...
