CPS — Oryza sativa Japonica

Summary

OsCPS (Os02g0571100) encodes a terpene synthase-like protein with syn-copalyl diphosphate synthase and ent-copalyl diphosphate synthase activities (EC 5.5.1.13), and isomerase activity that binds magnesium. In rice, this gene is associated with gibberellin and phytoalexin biosynthesis, hormone metabolism, diterpenoid metabolism, and response to UV-A. It is linked to plant height, grain number, grain weight, grain yield, seed dormancy, pre-harvest sprouting, spikelet fertility, stem elongation, culm diameter, drought tolerance, and allelopathic effect. Phenotypic associations include dwarfism, GA deficiency, temperature, defence, domestication, and seedling. Studies of related genes in other species link the family to seed germination, male sterility, flowering time, and GA-responsive dwarfism.
