Phenotypic and biochemical analyses of the tomato fruits of WT plants and single- (psy1, myb12, sgr1), double- (psy1 myb12, myb12 sgr1, psy1 sgr1), and triple- (psy1 myb12 sgr1) mutant lines in the BC1F2 generation. (A) Range of the color of tomato fruits obtained in this study. Photographs show the fully mature whole fruits as well as their cross-sections and peel. (B–E) Contents of β-carotene (B), lycopene (C), NarCh (D), and chlorophyll (E) in the fruits of seven isolated homozygous mutant genotypes and the WT. All compounds were quantified at 14 days after the breaker stage (Br + 14). Data represent mean ± standard deviation of three biological replicates. Lower-case letters indicate significant differences (P < .05; Student’s t-test). Scale bar = 2 cm.
