ASN — Triticum aestivum

Summary

TRAESCS4A02G109900 (TaASN) on wheat chromosome 4A encodes an asparagine synthase (glutamine-hydrolyzing) with aspartate-ammonia ligase activity, belonging to the Asn_synthase family. The gene is associated with L-asparagine anabolism, cellular response to sucrose starvation, response to fructose, glucose, and sucrose, hyperosmotic salinity response, and regulation of cell cycle processes. It has been linked to ABA response, nitrogen assimilation, metabolism, export, reutilization, ammonium metabolism, phosphate starvation tolerance, leaf senescence, salt stress tolerance, and plant growth. The encoded protein localizes to the cytosol, stress granules, and plasmodesmata. Studies of related genes in other species connect the family to grain protein content, seed weight, nitrogen recycling, drought tolerance, cold tolerance, water use efficiency, and grain yield.
