Signaling through MAP kinase networks in plants

摘要: Protein phosphorylation is the most important mechanism for controlling many fundamental cellular processes in all living organisms including plants. A specific class of serine/threonine protein kinases, mitogen-activated kinases (MAP kinases) play a central role transduction various extra- and intracellular signals are conserved throughout eukaryotes. These generally function via cascade networks, where MAP kinase (MAPK) phosphorylated activated by MAPK (MAPKK), which itself MAPKK (MAPKKK). Signaling through can lead to responses cell division, differentiation as well response stresses. In plants, represented multigene families organized into complex network efficient transmission stimuli. Putative plant cascades have been postulated based on experimental analysis vitro interactions between components. tested planta following expression epitope-tagged protoplasts. It known that signaling division stress plants mediated even auxin, ABA possibly ethylene cytokinin also utilize pathway. Most biotic (pathogens pathogen-derived elicitors) wounding abiotic stresses (salinity, cold, drought, oxidative) induce defense pathways. this article we covered historical background, biochemical assay, activation/inactivation, targets with emphasis regulated them. The cross-talk discussed bring out complexity within three-component module.
