Genome-wide identification and characterization of genes involved in carotenoid metabolic in three stages of grapevine fruit development

Abstract Carotenoids not only play indispensable roles in plant growth and development but also enhance nutritional value and health benefits for humans. In this study, total carotenoids progressively decreased during fruit ripening. Fifty-four genes involving in mevalonate (MVA), 2-C-methyl-D-eryth...
