Combination mutants have altered adult development. Phenotypic responses were examined for the wild type and combination mutants after being grown under continuous light at 22°C, including the number of apical stems (A), the number of days until bolting (B), the ratio of curled leaves to normal rosette leaves (C), rosette diameter (D), and plant height (E). F, Silique length was examined as one indicator of fertility by measuring the length of siliques 5 to 8 at maturity. Insets, One representative wild-type plant and one representative mutant plant. A to E, n ≥ 15; F, n ≥ 30. a to c, Significant differences using one-way ANOVA (P < 0.05).
