GS5 — Oryza sativa Indica Group

Summary

BGIOSGA018771 (GS5) on chromosome 5 of Indica rice encodes a serine carboxypeptidase with hydroxymandelonitrile lyase and acyltransferase activities, belonging to the peptidase S10 family. The protein localises to the apoplast, vacuole, plant-type cell wall, ER, plasmodesma and extracellular space. GS5 is associated with proteolysis, cell growth, secondary metabolism, arbuscular mycorrhizae formation, response to symbiotic fungi and genetic transfer. The gene is associated with grain size, grain length, grain width, grain thickness, grain weight, grain yield, panicle length, plant height, leaf width and heterosis. Related genes in other species are linked to seed dormancy, germination, drought tolerance, root morphology, grain protein content and vascular bundle number.
