CPS — Zea mays

Summary

ZM00001EB021200 (CPS, ZmCPS) on maize chromosome 1 encodes a terpene synthase with ent-copalyl diphosphate synthase activity (EC 5.5.1.13), placing it in the isoprenoid synthase domain superfamily. The gene is associated with gibberellin metabolism, diterpenoid metabolism, and the biosynthesis of phytoalexins, miltiradiene, carotene, and abscisic acid. It is linked to regulation of pigmentation, pigment accumulation, tube development, and response to gravity and stimulus. Traits associated with this gene include grain yield, drought tolerance, plant height, seedling height, anthesis-silking interval, harvest index, tiller number, chlorophyll content, leaf color, and popping expansion volume. Phenotypes linked to the gene encompass dwarfism, flowering time, plant development, gibberellin biosynthesis, and photooxidative stress resistance. Studies of related genes in other species connect the family to seed germination, male fertility, and stamen length.
