GS2 — Brassica napus

Summary

BnGS2 (DARMORV10_A08P09830.1) on chromosome A08 of oilseed rape encodes a glutamine synthetase, as indicated by its glutamine synthetase activity and glutamine synthetase domain signatures. The gene is associated with nitrogen metabolism, including nitrate import and assimilation, the ammonia assimilation cycle, and photorespiration. It has been linked to traits such as soluble protein content, seed size, photosynthetic rate, drought tolerance, and flowering time. Associations also include chlorophyll metabolism, response to cadmium, and blue light response. The encoded protein is localized to plastids, chloroplasts, thylakoids, and mitochondria. Related genes in other species are linked to nitrogen assimilation, biomass accumulation, and photoperiodic flowering.
