CPS — Zea mays

Summary

ZM00001EB048020 (CPS, also known as ZmCPS) on maize chromosome 1 encodes a terpene synthase with ent-copalyl diphosphate synthase activity (EC 5.5.1.13). The gene is associated with plant height, grain yield, anthesis-silking interval, days to tassel emergence, popping expansion volume, seedling height, root length, leaf trichome density, leaf water potential, chlorophyll content, cold tolerance, drought tolerance, nitrogen content, and harvest index. It is associated with gibberellin biosynthesis, dwarfism, flowering time, carotenoid and chlorophyll biosynthesis, photooxidative stress resistance, and trichome formation. The encoded protein localizes to the chloroplast and contains terpene cyclase and synthase domains. Studies of related genes in other species connect the family to seed germination, male fertility, stem elongation, and allelopathy.
