Gabaculine-treated Y-05 seedlings show yellow leaves phenotype without cold acclimation. a The gabaculine-treated plants showed yellow phenotype without cold-acclimation. Before, plants before treated with gabaculine. After, plants after treated with gabaculine. 0 μM and 50 μM represented CK plants and gabaculine-treated plants, respectively. Bar = 5 cm. b The inner leaves of gabaculine-treated plants showed low chlorophyll content compared with CK plants. c The inner leaves of gabaculine-treated plants showed low ALA content compared with CK plants. Three individual plants of each cultivar were quantified, and the chlorophyll and ALA content were measured three times. Error bars represent SE (±SE, n = 3). * represents p < 0.05, ** represents p < 0.01
