Did you know?
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 ).
