SUB1 — Oryza sativa Japonica

Summary

Rice gene SUB1 (OS07G0633600) on chromosome 7 encodes a protein with transglycosidase activity and calcium ion binding, belonging to the DUF7075 and DUF7074 domain families. SUB1 is associated with submergence tolerance. The gene is associated with carbohydrate breakdown, anaerobic respiration, regulation of seed development, sterol metabolism, hypersensitivity, seed development, homeostasis, DNA repair, and cell cycle processes. It localizes to the nuclear membrane-ER network and Golgi complex. SUB1 is also associated with grain yield, plant height, tiller number, chlorophyll content, carbohydrate content, and salinity tolerance. Additionally, it is associated with far-red and blue light responses and photomorphogenesis. Studies of related genes in other species link the family to panicle weight, panicle length, flowering time, and light sensitivity traits.
