Abstract excerpt

We investigated the transcriptional regulation of six genes involved in carotenoid biosynthesis, together with the carotenoid accumulation during postharvest ripening of three different papaya genotypes of contrasting pulp color. Red-pulp genotype (RPG) showed the lowest content of yellow pigments (YP), such as β-cryptoxanthin, zeaxanthin, and violaxanthin, together with the lowest relative expression levels...
