Note: The data represent the mean (μg g−1 fresh weight) ± SD from five biological replicates. Carotenoid contents were determined at three different ripening stages. The mean values were compared between genotypes at the same ripening stage, with different lowercase letters indicating significant differences (P < 0.05, Student’s t-test). The tomato inbred lines oft3 and the r mutant TB0040 were originally developed in our lab.
