CPS — Oryza sativa Japonica

Summary

OsCPS (Os02g0278700) encodes a terpene synthase with ent-copalyl diphosphate synthase and copal-8-ol diphosphate synthase activities (EC 5.5.1.13), placing it in the isoprenoid synthase domain superfamily. In rice, the gene is associated with gibberellin biosynthesis and deficiency, dwarfism, domestication, seedling development, and responses to UV-A. It has been linked to diterpenoid and phytoalexin metabolism, polyamine metabolism, chloroplast fission, stomatal closure, dehiscence, and pre-harvest sprouting. Associations with agronomic traits include plant height, grain number, grain weight and yield, spikelet and pollen fertility, stem diameter and elongation, seed dormancy, germination rate, leaf chlorosis, and drought tolerance. Studies of related genes in other species link the family to seed germination, flowering time, male fertility, and stem elongation.
