Provitamin A (Pro-VA) is necessary for human vision and immune system health, especially in growing children. The first committed step in the maize carotenoid biosynthesis pathway is catalyzed by phytoene synthase 1 (encoded by PSY1) which controls the flux of substrates into the pathway. The flow of these substrates could be directed into production of the β-branch carotenoids (the step controlled largely by the...
