Gradual suppression of the cytokinin response by JA. (a) Suppression of the cytokinin response by JA was analyzed in a time course by monitoring fluorescent signals in ARR5::GFP plants. Five-day-old ARR5::GFP plants grown without JA were transferred to MS media containing 10 μM MeJA, and grown for the indicated times. Mock indicates MS media containing 0.05% EtOH. White arrows and arrowheads indicate cytokinin response in the vascular tissue and root cap, respectively. (b) Quantification of extra xylem formation in these plants (n > 20). Percentages were calculated by dividing the number of plants with extra xylem by the number of plants observed. Scale bar = 20 μm.
