Blocking anthocyanin accumulation using different mutants affecting anthocyanin biosynthetic genes showed different effects on fruit shelf life. A, Phenotypes of Del/Ros1 tomato crossed with anthocyanin biosynthetic mutants. B, Antioxidant capacity of different fruit. Fruit were harvested at 14 d post breaker. Error bars show se (n = 3). Different letters indicate significantly different values at P < 0.05 (one way ANOVA, Tukey’s posthoc test) using the same extraction method. FW, Fresh weight. C, Storage tests of different fruit. Fruit were harvested 2 weeks after breaker, and the times needed to show overripening symptoms (visual rotting and collapse of fruit) were recorded. Error bars show se (n = 10). Different letters indicate significantly different values at P < 0.05 (multiple pairwise comparison using χ² test). WT, Wild type.
