SUB1 — Oryza sativa Indica Group

Summary

BGIOSGA023856 (SUB1, OiSUB1) on chromosome 7 of Indica rice encodes a protein containing DUF7075 and DUF7074 domains, with annotated transglycosidase activity and calcium ion binding. The gene is associated with submergence tolerance. Annotated biological processes include fermentation, starch metabolism, chlorophyll breakdown, and signal transduction, while the product localises to the nuclear membrane-ER network and Golgi complex. Additional associations link SUB1 to panicle weight, panicle length, grain yield, salinity tolerance, and responses to far-red and blue light as well as photomorphogenesis. Studies of related genes in other species connect the family to agronomic traits such as tiller number, plant height, days to flowering, chlorophyll content, and carbohydrate content, though these relationships are not established for this gene.
