Cytokinin - a developing story
WebBriefly, cytokinins directly bind to and stimulate a family of histidine kinases ( ARABIDOPSIS HISTIDINE KINASE (AHK) 2, AHK3, and AHK4) that phosphorylate AHPs, which then transfer phosphorylation and thus activate ARABIDOPSIS RESPONSE REGULATORs (ARRs), a large family of diverse transcription factors ( Müller and Sheen, 2007 ). WebModifying the cytokinin content in plants is a means of improving plant productivity. Here, we report the development and biological activity of compound TD-K (1-(furan-2-ylmethyl)-3-(1,2,3-thiadiazol-5-yl)urea)which is related to thidiazuron. TD-K—which exhibited extremely high antisenescence activity in the wheat leaf bioassay—and INCYDE (2 …
