CPS — Oryza sativa Japonica

Summary

OsCPS (OS04G0178300) encodes a terpene synthase-like protein with syn-copalyl diphosphate synthase and ent-copalyl diphosphate synthase activities, and is annotated with isomerase activity and magnesium binding. In rice, the gene is associated with gibberellin biosynthesis and deficiency, dwarfism, allelopathy, seedling growth, and domestication. It is linked to diterpenoid and phytoalexin biosynthesis, hormone metabolism, pre-harvest sprouting, anther development, stomatal closure, and response to UV-A. Associations extend to grain yield, grain weight, grain number, seed dormancy, germination rate, plant height, stem diameter, spikelet fertility, pollen fertility, drought tolerance, and leaf chlorosis. Studies of related genes in other species connect the family to seed germination, male sterility, and GA-responsive dwarfism, as well as days to tassel emergence and anthesis-silking interval.
