Article
Effect of codon optimization on the enhancement of the β-carotene contents in rice endosperm
A β-carotene is the most well-known dietary source as provitamin A carotenoids. Among β-carotene-producing Golden Rice varieties, PAC (Psy:2A:CrtI) rice has been previously developed using a bicistronic recombina...

In planta cleavage of carotenoids by Arabidopsis carotenoid cleavage dioxygenase 4 in transgenic rice plants
A family of carotenoid cleavage dioxygenases (CCDs) produces diverse apocarotenoid compounds via the oxidative cleavage of carotenoids as substrates. Their types are highly dependent on the action of the CCD f...
