Phenotypes of the lutescent mutants. A, Phenotypes of developing and ripening fruit of l1 and l2 mutants compared to wild-type (AC) fruit. B, Confocal laser-scanning microscopy images of AC, l1, and l2 fruits at the mature stage of development showing chlorophyll autofluorescence. C, Chloroplast number per cell in immature green fruit pericarp at 20 d post anthesis. Data are presented as the mean ± se of at least 103 cells. Means followed by different letters indicate statistical significance at α = 0.05. D, Image of a mature l1 fruit displaying elevated anthocyanin accumulation in the fruit peel. E, Chlorophyll-deficient phenotypes in the pistils of l1 and l2. F, Fully expanded leaflets of AC, l1, and l2 highlighting increased susceptibility to chlorophyll loss in each mutant. G, Phenotype of 3-week-old AC, l1, and l2 plants grown under high-light conditions. H, Chlorophyll breakdown in the dark in leaves of l2 e3779. Chlorophyll concentration was determined in leaves of plants of mutant l2 e3779 and its isogenic wild-type cv M82 grown for either 7 weeks in the light or 5 weeks in the light followed by 14 d under complete darkness. Data are presented as the mean ± se (n = 6).
