GCS1 — Glycine max

Summary

GmGCS1 (GLYMA_09G081600V4) encodes a HAP2/GCS1 domain-containing protein with lipid-binding molecular function. In soybean, this gene is associated with double fertilization, specifically the fusion of sperm to egg plasma membrane, as well as pollen sperm cell differentiation and protein-membrane insertion. It has been connected to seed development, seed size, seed width, seed length, and seed weight traits, along with stearic and palmitic acid content, net photosynthetic rate, and salinity response including activation of salinity response. The gene is linked to nitrogen fixation, nodulation, fatty acid metabolism and anabolism, lipogenesis, and homeostasis. Its product localizes to the cell projection membrane, cytoplasmic vesicle membrane, ER membrane, and plasmalemma. Studies of related genes in other species link the HAP2/GCS1 family to gamete fusion and pollen tube guidance.
