GCS1 — Glycine max

Summary

GmGCS1 (GLYMA_11G026100V4) on soybean chromosome 11 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, as well as pollen sperm cell differentiation, seed development, nodulation, nitrogen fixation, and responses to salt stress. It is also associated with fatty acid metabolism, lipogenesis, and homeostasis. Localization evidence links the product to cell projection membranes, cytoplasmic vesicle membranes, the ER, and the plasma membrane. Associations with agronomically important traits include seed width, seed length, seed weight and size, stearic and palmitic acid content, net photosynthetic rate, and salt tolerance. Studies of related genes in other species link the family to gamete fusion and male gametophyte transmission defects.
