WebIn general, TCs are located at strategically important positions for nutrient acquisition and exchange, such as symplasmic/apoplasmic interfaces in vascular tissues and seeds, reproductive and secretory organs and at contact points of plant/symbiotic and plant/parasitic interactions. WebCytokinins propagate signals via multiple phosphorelays in a mechanism similar to bacterial two-component systems. In Arabidopsis, signal outputs are determined by the activation state of transcription factors termed type-B Arabidopsis response regulators (ARRs); however, their regulatory mechanisms are largely unknown. In orthodox two-component signaling, a histidine kinase protein autophosphorylates on a histidine residue in response to an extracellular signal, and the phosphoryl group is subsequently transferred to an aspartate residue on the receiver domain of a response regulator. In phosphorelays, the "hybrid" histidine kinase contains an internal aspartate-containing receiver domain to which the phosphoryl group is transferred, after which an HPt protein containing a ph… dainty wok dickinson
