Cytokinin signal transduction
WebThis bud induction can be pinpointed to differentiation of a specific single cell, and thus is a very specific effect of cytokinin. Mode of action. Cytokinin signaling in plants is … WebOct 14, 2005 · Cytokinin signal transduction is mediated by a multistep phosphorelay that transfers the signal from the plasma membrane to the nucleus. Type-B ARRs act as transcription factors, one target being genes encoding type-A ARRs. The type-A ARRs feed back to inhibit their own transcription and may also mediate other cytokinin responses.
