SCF(KMD) controls cytokinin signaling by regulating the degradation of type-B response regulators.

Proceedings of the National Academy of Sciences of the United States of America - 11 Jun 2013

Abstract excerpt

Cytokinins are plant hormones that play critical roles in growth and development. In Arabidopsis, the transcriptional response to cytokinin is regulated by action of type-B Arabidopsis response regulators (ARRs). Although central elements in the cytokinin signal transduction pathway have been identified, mechanisms controlling output remain to be elucidated. Here we demonstrate that a family of F-box proteins,...
