ERD2 — Oryza sativa Indica Group

Summary

BGIOSGA035736 (ERD2, OiERD2) on chromosome 11 of indica rice encodes a member of the Hsp70 family, an ATP-dependent protein folding chaperone with ATPase and heat shock protein binding activities. The gene is associated with diverse biological processes including protein folding in the endoplasmic reticulum, cytosol-to-ER transport, RuBisCO assembly, mitochondrial matrix protein import, and responses to humidity, salicylate, and chlorate. It has been linked to traits such as grain filling period, spikelet fertility, grain yield per plant, biomass yield, photosynthetic ability, carotenoid content, leaf necrosis, variegated leaf, and responses to zinc, gibberellic acid, ethylene, brassinosteroids, and herbicides. The gene is also connected to seedling growth, temperature and salt responses, and cell cycle regulation. Studies of related genes in other species link the family to heat stress tolerance, leaf senescence, innate immunity, and photosynthetic capacity.
