Illumina^® Sequencing Reveals Candidate Genes of Carotenoid Metabolism in Three Pummelo Cultivars (Citrus Maxima) with Different Pulp Color.

ABSTRACT: Pummelo (Citrus maxima) is one of important fruit trees, which belongs to Citrus species. The fruits of different pummelo cultivars have different colors and differ in the contents of carotenoid. Our results clearly showed that 'Huangjinmiyou' (HJMY) has the highest content of β-carotene, followed by 'Hongroumiyou' (HRMY) and 'Guanximiyou' (GXMY). Lycopene is dominantly accumulated in HRMY. However, the molecular mechanism underlying the carotenoid accumulation in pummelo flesh is not fully understood. In this study, we used the RNA-Seq technique to investigate the candidate genes of carotenoid metabolism in the flesh of pummelo cv. GXMY and its mutants HRMY and HJMY in three development periods of fruit. After data assembly and bioinformatic analysis, a total of 357 genes in
