Cytokinin signal perception and transduction.
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 continuously variable signalling that is directly dependent on the h...
متن کاملPhosphorelay and transcription control in cytokinin signal transduction.
The past decade has seen substantial advances in knowledge of molecular mechanisms and actions of plant hormones, but only in the past few years has research on cytokinins begun to hit its stride. Cytokinins are master regulators of a large number of processes in plant development, which is known to be unusually plastic and adaptive, as well as resilient and perpetual. These characteristics all...
متن کاملThe type-A response regulator, ARR15, acts as a negative regulator in the cytokinin-mediated signal transduction in Arabidopsis thaliana.
The Arabidopsis thaliana AHK4 histidine kinase (also known as CRE1 or WOL) acts as a cytokinin signal transducer, presumably, in concert with downstream components, such as histidine-containing phosphotransfer factors (AHPs) and response regulators (ARRs), through the histidine-to-aspartate (His-->Asp) phosphorelay. Among 10 members of the type-A ARR family, the cytokinin-induced expression of ...
متن کاملMultiple routes communicating nitrogen availability from roots to shoots: a signal transduction pathway mediated by cytokinin.
In higher plants, inorganic nitrogen has crucial effects on growth and development, providing cellular components and modulating gene expression. To date, not only nitrogen assimilatory genes but also a substantial number of genes with other functions have been shown to be selectively regulated by the availability of nitrogen. In terms of the communicating substance(s) between root and shoot, a...
متن کاملThe ethylene signal transduction pathway in plants.
Ethylene (C2H4), the chemically simplest plant hormone, is among the best-characterized plant growth regulators. It participates in a variety of stress responses and developmental processes. Genetic studies in Arabidopsis have defined a number of genes in the ethylene signal transduction pathway. Isolation of two of these genes has revealed that plants sense this gas through a combination of pr...
