| physiological function | zeaxanthin oxidase is the major contributor to carotenoid composition, with mutants lacking ZEP activity showing a 6fold increase in total seed carotenoids relative to the wild type. Natural variation in ZEP gene expression during seed development is the underlying mechanism for fine-tuning carotenoid composition, stability, and ultimately content in Arabidopsis seed. ZEP acts as an upstream control point of carotenoid homeostasis, with ZEP-mediated epoxidation targeting carotenoids for degradation by carotenoid clevage dioxygenase enzymes | Arabidopsis thaliana |
