ASN1 — Glycine max

Summary

GmASN1 (GLYMA_11G170300V4) encodes an asparagine synthase with glutamine-hydrolyzing activity and ATP binding, placing it in the AsnB_N and Asn_synthase domain families. In soybean, this gene is associated with asparagine and ureide anabolism and breakdown, nitrogen utilization and fixation, nitrate import, and responses to sucrose starvation, fructose, and flooding. It has been linked to leaf chlorophyll content, seed protein content, seed weight, heterosis, drought tolerance, and salt stress tolerance, as well as nitrogen-limiting stress tolerance, phosphate starvation tolerance, and leaf senescence. The gene is also associated with the lipoxygenase pathway, ALA metabolism, oxidative phosphorylation, glycerolipid metabolism, regulation of DNA replication, systemic acquired resistance, and Pi homeostasis. Studies of related genes in other species link the family to seed nitrogen content.
