The transcriptional repressor ARR1-SRDX suppresses pleiotropic cytokinin activities in Arabidopsis.

Plant physiology - 1 Jul 2008

Abstract excerpt

The signal transduction of the phytohormone cytokinin is mediated by a multistep histidine-to-aspartate phosphorelay system. One component of this system are B-type response regulators, transcription factors mediating at least part of the response to cytokinin. In planta functional analysis of this family is hampered by the high level of functional redundancy of its 11 members. We generated a dominant repressor...
