Phenotypes of wild-type (WT), hcf243, and hcf243 complemented plants. A, Six-week-old wild-type (left), hcf243 (middle), and hcf243 complemented (right) plants. B, Growth kinetics of hcf243 mutants compared with wild-type plants. Values shown are means ± se of three biological replicates; each replicate represents six transgenic plants.
