Morphology of seedlings and calli induced from each genotype. (A) Phenotypes of Ws-2 wild type and the dwf7-1 mutant. As compared with wild type, dwf7-1 exhibited severe dwarfism. Scale bar = 0.5 cm. (B) Callus morphology resulting from the different genotypes. Each genotype successfully established calli when the explants were grown for 30 days in callus induction medium. The sizes of dwf7-1 calli were relatively small compared to the wild-type calli. Unit bar = 0.2 cm.
