Figure 4.

Analysis of shoot, fruit, and seed development. Arabidopsis aap2 and wild-type (WT) plants were grown in 16-h days for 6 weeks under low-, moderate-, or high-N conditions. A, Composite images of two aap2 mutant lines and wild-type plants. Mutant and wild-type plants from each N treatment were photographed. The three images were put on black backgrounds, assembled in a panel, and labeled using Adobe Photoshop CS5. B, Total shoot dry weight per plant (n ≥ 10). C, Total surface area of rosette leaves (n ≥ 3). D, Total branch number per plant (n ≥ 8). E, Siliques per branch (n ≥ 8). F, Total siliques per plant (n ≥ 7). G, Seeds per silique on the main branch (n ≥ 17). Data are means ± sd. Significant differences are indicated by letters (ANOVA; P ≤ 0.05).
