GCS1 — Glycine max

Summary

GmGCS1 (GLYMA_15G240000V4) on soybean chromosome 15 encodes a HAP2/GCS1 domain-containing protein with lipid-binding molecular function. This gene is associated with double fertilization, specifically fusion of sperm to egg plasma membrane, pollen sperm cell differentiation, and protein-membrane insertion. It has been linked to seed development, seed size, seed width, seed length, and seed weight traits, as well as stearic and palmitic acid content, net photosynthetic rate, and nitrogen fixation. Associations with nodulation, salinity response and activation of salinity response, fatty acid metabolism and anabolism, lipogenesis, and homeostasis are also observed. The protein localizes to cell projection and cytoplasmic vesicle membranes, ER membrane, plasmalemma, and extracellular regions. Related genes in other species are linked to gamete fusion and male gametophyte transmission.
