ERD2 — Oryza sativa Japonica

Summary

Rice gene ERD2 (HSP70, Os11g0703900) encodes a member of the Hsp70 family, characterized by an ATPase domain and heat shock 70 conserved signature, and is annotated with ATP-dependent protein folding chaperone activity, calcium-dependent phospholipid binding, and DXP-synthase activity. This gene is associated with diverse biological processes including protein denaturation, cell glucose homeostasis, response to humidity, cytosol-to-ER transport, RuBisCO assembly, and upregulation of defense responses to oomycetes. It has been linked to numerous agronomic traits such as grain shape, grain length and width, grain filling period, biomass yield, photosynthetic ability, carotenoid content, leaf water potential, root and shoot fresh and dry weights, and responses to salt, temperature, chilling, and herbicide. Localization evidence connects the product to the ER chaperone complex, thylakoid lumen, mitochondrial outer membrane, and nuclear matrix. Related genes in other species are linked to pathogen resistance, salicylic acid signaling, and cell death phenotypes.
