DHS — Triticum aestivum

Summary

TRAESCS3D02G042300 (symbol DHS, also known as TaEDA22-3D) on bread wheat chromosome 3D encodes a protein with deoxyhypusine synthase and homospermidine synthase (spermidine-specific) activities, belonging to the deoxyhypusine synthase-like NAD/FAD-binding domain family. This gene is associated with spermidine metabolism, embryo sac development, and heat acclimation, and its product localizes to both the cytoplasm and nucleus. DHS is associated with heat tolerance and Fusarium head blight resistance. Related genes in other species are linked to traits including seed yield, seed weight, drought tolerance, leaf senescence, and vegetative and reproductive growth time, as well as biomass and bolting time.
