Leaf development phenotypes in svr9-1, svr9l1-1, and svr9-1 svr9l1-1/+ mutants. A, Photographs of the third true leaves of representative 2-week-old wild type, svr9l1-1, svr9-1, and svr9-1 svr9l1-1/+. Bars, 1 mm. B to D, Quantitative comparisons of leaf shapes in wild type, svr9l1-1, svr9-1, and svr9-1 svr9l1-1/+ based on the leaf dissection index (perimeter²/4π × leaf area) (B), the number of teeth/leaf perimeter (C), and the tooth area/leaf area (D). All measurements were performed on the third true leaves of 2-week-old plants. Ten leaves of each genotype were included in the statistical analysis. Data were presented as mean ± sd. ***P < 0.001. E, Cross sections of the basal part of the first true leaves of 10-d-old wild type, svr9-1, and svr9-1 svr9l1-1/+. Bars, 50 μm. F, Common cotyledon vein patterns observed in wild type, svr9-1, and svr9-1 svr9l1-1/+. WT, Wild type.
