CPS — Oryza sativa Indica Group

Summary

BGIOSGA008469 (CPS, CPS2) on chromosome 2 of Indica rice encodes a syn-copalyl diphosphate synthase with ent-copalyl diphosphate synthase, terpene synthase and isomerase activities, and belongs to the terpene synthase-like family. The gene is associated with gibberellin biosynthesis and signaling, diterpenoid and secondary metabolite biosynthesis, defense response, and signal transduction. It has been linked to allelopathy, domestication, seedling growth, dwarfism, and GA deficiency in rice. Associations also include flowering time, plant development, petiole length, trichome formation, apical hook formation, root colonization, photooxidative stress resistance, and chlorophyll and carotenoid biosynthesis. The encoded protein localises to the chloroplast. Studies of related genes in other species connect the family to seed germination, male sterility, stem height, and floral organ development.
