VP14 — Zea mays

Summary

ZM00001EB140120, also known as VP14, is a maize gene on chromosome 3 that encodes a carotenoid dioxygenase with 9-cis-epoxycarotenoid dioxygenase activity and metal binding. The gene is associated with abscisic acid anabolism, carotene breakdown, and the anabolism of lycopene, beta-carotene, xanthophyll, anthocyanin, and isoprenoids. It has been linked to meristem, anther, endosperm, and seed maturation development, as well as stomatal closure, fruit ripening, and responses to gibberellin and salicylate. The encoded protein localizes to the chloroplast thylakoid membrane and stroma. VP14 is also associated with grain color and stomatal resistance traits. Related genes in other species link the family to the enzyme class 1.13.11.51.
