Transcription profiling of Arabidopsis Col-0 wild-type and 35S:ARR1-SRDX transgenic seedlings either induced with 6-Benzyladenine or mock-treated

ABSTRACT: 6 days old Arabidopsis thaliana of Col-0 wild-type and 35S:ARR1-SRDX transgenic seedlings grown in liquid culture (1/2 MS, 1 g/L sucrose, 0.5 g/L MES, pH 5.7) were induced with either 5 µM 6-Benzyladenine (a cytokinin analog) for 15 or 120 min, or mock-treated 120 min as a control. These samples were subjected to microarray analysis.

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 version of the Arabidopsis (Arabidopsis thaliana) response regulator ARR1 (ARR1-SRDX)  ...[more]
