1.3.5.6 metabolism the enzyme is important in carotenoid biosynthesis pathway in citrus fruits, overview Citrus sinensis
1.3.5.6 physiological function Zds is a key gene important in the regulation of carotenoid accumulation, including the early steps of the pathway, regulated during fruit maturation. Altered flow of carotenoid precursors during fruit maturation due to abscission agents is suggested by changes in phytoene desaturase and zeta-carotene desaturase gene expression. As fruit mature, increased phytoene desaturase (Pds) and zeta-carotene desaturase (Zds) gene expression result in increased downstream carotenoid content Citrus sinensis
