GPA1 — Glycine max

Summary

GmGPA1 (GLYMA_17G226700V4) encodes a plant G protein alpha subunit, a member of the heterotrimeric G-protein complex family, and is associated with G protein-coupled receptor binding, GTPase inhibitor activity, and abscisic acid binding. The gene is linked to the regulation of stomatal opening, reactive oxygen species-mediated programmed cell death, and maintenance of seed dormancy. It localizes to plastid membranes, the heterotrimeric G-protein complex, and endosome membranes. Associations with agronomically important traits include seed quality, grain size, seed protein content, seed weight, germination rate, bacterial blight disease resistance, salt response, and days to flowering. Studies of related genes in other species connect the family to glucose signaling, seed dormancy, drought response, and disease resistance to Pseudomonas syringae.
