WebOct 5, 2007 · Cytokinins are essential plant hormones that control various processes in plants' development and response to external stimuli. The Arabidopsis cytokinin signal transduction pathway involves hybrid histidine protein kinase sensors, phosphotransfer proteins, and regulators as transcription activators and repressors in a phosphorelay … 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 ). WebAug 3, 2012 · Thus, CKs might play roles in growth and/or maintenance of pedicels. Auxin accumulates in pedicels during early tomato fruit development and is thought to prevent premature abscission of ovaries (Nishio et al., 2010). CK application to developing Arabidopsis tissues leads to upregulation of auxin biosynthesis (Jones et al., 2010). CKs … chinchero textiles
