GS1 — Triticum aestivum

Summary

TRAESCS7B02G017100, designated TaGS1 on bread wheat chromosome 7B, encodes a glycerol-1-phosphatase (EC 3.1.3.21) with sn-glycerol 3-phosphatase activity and metal binding, belonging to the Gpp1/Gpp2-like and HAD-superfamily hydrolase families. The gene is associated with nitrogen metabolism, nitrogen utilization, and ureide breakdown, as well as glycerol anabolism, photorespiration, phloem transport, leaf senescence, leaf development, and homeostasis. Associations with agronomically important traits include grain yield, grain number, grain weight, grain protein content, spike length, spikelet length, anther length, flag leaf senescence, grain filling period, chlorophyll content, root length, seed germination, and salinity tolerance. The gene is also linked to nitrogen recycling, meristem identity, and phenylpropanoid anabolism.
