CPS — Oryza sativa Indica Group

Summary

BGIOSGA015502 (OiCPS) on chromosome 4 of Indica rice encodes a terpene synthase with syn-copalyl diphosphate synthase and ent-copalyl diphosphate synthase activities, and is associated with diterpenoid metabolism. The gene is associated with gibberellin metabolism and signaling, diterpene phytoalexin anabolism, and defense response. Observed phenotypes link it to dwarfism, GA deficiency, growth, seedling development, domestication, and allelopathy. It is also associated with gibberellin biosynthesis, flowering time, plant development, petiole length, trichome formation, apical hook formation, root colonization, and photooxidative stress resistance, as well as chlorophyll and carotenoid biosynthesis. Related genes in other species are linked to seed germination, male sterility, and stamen and petal length, as well as days to tassel emergence and anthesis-silking interval.
