The bige1 Mutant Has Increased Lateral Organ Number during Vegetative Development.

(A) Number of adventitious roots formed at the first node of the wild type (white circles) and bige1-umu1 mutant (filled circles) seedlings. Error bars indicate se. The differences in root number between the wild type and bige1 mutant were statistically significant by Student’s t test (P < 0.05), except at 6 and 7 DAS.

(B) Number of emerged leaves produced by wild-type (white circles) and bige1 mutant (filled circles) plants. At 7 weeks after sowing, all mutant plants had flowered, whereas wild-type plants flowered 1 week later. The differences in leaf number between the wild type and bige1 mutant were statistically significant by Student’s t test at all stages (P < 0.05).

(C) Wild-type (left) and bige1 mutant (right) adult plants at the time of tassel emergence from the apex of the bige1 plant. The tassel was not yet visible in the apex of the wild-type plant.
