TPS — Zea mays

Summary

ZM00001EB415160 (ZmTPS, also known as TPS31, TPS10, or TPS2) on maize chromosome 10 encodes a terpene synthase with multiple sesquiterpene and monoterpene synthase activities, including sesquithujene, gamma-curcumene, endo-alpha-bergamotene, alpha-zingiberene, beta-sesquiphellandrene, (-)-E-beta-caryophyllene, and alpha-copaene synthase activities (EC 4.2.3.125, 4.2.3.81, 4.2.3.65, 4.2.3.123, 4.2.3.57, 4.2.3.133, 4.2.3.47). The gene is associated with terpene, diterpenoid, monoterpene, triterpenoid, and phytoalexin biosynthesis, as well as abscisic acid anabolism, primary metabolism, and responses to starvation. It has been linked to ear development, grain number, grain yield, plant height, fruit dimensions, drought tolerance, and resistance. Related genes in other species connect the family to defense against brown planthopper and submergence tolerance. The protein localizes to the cytoplasm.
