ASN — Triticum aestivum

Summary

TRAESCS5B02G152600, designated TaASN on wheat chromosome 5B, encodes an asparagine synthetase [glutamine-hydrolyzing] (EC 6.3.5.4), conferring asparagine synthase (glutamine-hydrolyzing) activity and ATP binding. The gene is associated with L-asparagine anabolism, glutathione anabolism, cell wall polysaccharide breakdown, mucilage extrusion from the seed coat, response to desiccation, brassinosteroid, oxidative stress, and other organisms, as well as auxin signaling and NO storage. TaASN is associated with grain number, grain texture, plant height, drought tolerance, osmotic response sensitivity, abscisic acid sensitivity, and salt tolerance. It is associated with seeds per head, grain hardness, head wax, and SDS sedimentation. The protein localizes to the cytosol. Studies of related genes in other species connect the family to ABA and osmotic stress responses.
