Cytokinin signal transduction
WebAbstract. Cytokinins are essential hormones for the proper growth and development of plants. They exert their actions through the phosphorylation of two-component … WebOct 1, 2003 · In the past few years, enormous progress has been made in understanding cytokinin perception and signalling. Three cytokinin receptor proteins, which are hybrid histidine kinases, have been identified in Arabidopsis. These receptors may transduce signals in a quantitative rheostat-like fashion, thus permitting long-lasting and …

WebAbstract. Cytokinins are plant hormones implicated in diverse and essential processes in plant growth and development, and key genes for the metabolism and actions of cytokinins have recently been identified. Cytokinins are perceived by three histidine kinases—CRE1/WOL/AHK4, AHK2, and AHK3—which initiate intracellular phosphotransfer. grand prize chevrolet buick gmc cadillacWebComparative genomic analyses were performed to trace the origin, evolution and diversification of the critical regulatory networks linking CK signaling and abiotic stress.
