GPAT (TRAESCS1D02G278000) — triticum aestivum

Summary

TRAESCS1D02G278000, designated TaGPAT (also known as TaGPAT6, RAM2, TaGPAT-1D), encodes a glycerol-3-phosphate 2-O-acyltransferase on wheat chromosome 1D, placing it in the HAD_RAM2/GPAT1-8 family with additional phosphatase and hydrolase activities. The gene is associated with salt tolerance in bread wheat, as observed for GPAT6 in this species, and is linked to the SALTTL trait. Its annotated biological processes include glycerolipid metabolism, phospholipid and cutin anabolism, arbuscular mycorrhizae formation, and response to symbiotic fungi, with the product localised to membranes. Studies of related genes in other species connect the family to phosphate content, chlorophyll content, quantum yield, growth stage, physiological traits, and heterosis, though these associations are not yet established in wheat.
