Salk, ear, and tassel phenotypes of zmccd8 mutants. A, Internode length in zmccd8 mutant and wild-type plants. Internodes were numbered from tassel to base. In zmccd8, internodes between positions 5 and 14 were significantly shorter (P < 0.01, ANOVA). The internodes immediately above ear nodes are marked with arrows. Values are means ± se (n = 10). B, Statistical analysis of ear phenotypes of zmccd8 mutant and the wild type. Data were collected from dry mature ear. Asterisks indicate statistically significant differences between ears of mutant and the wild type (P < 0.0001, ANOVA). Values are means ± se (n = 20 to approximately 50). C, The drooping-tassel phenotype of the zmccd8 mutant is shown at anthesis. [See online article for color version of this figure.]
