There are many varieties of carotenoids in pepper fruits. Capsanthin is a red carotenoid that gives mature pepper fruits their red color. The red color in pepper fruits is regulated mainly by the genes capsanthin/ capsorubin synthase(Ccs), phytoene synthase(Psy), lycopene-β-cyclase(Lcyb) and β-carotene hydroxylase(Crtz). | Nội dung Text Effects of silencing key genes in the capsanthin biosynthetic pathway on fruit color of detached pepper fruits
