SHN1 — Triticum aestivum

Summary

TRAESCS7A02G376300 (SHN1) on wheat chromosome 7A encodes an AP2/ERF subfamily transcription factor with sequence-specific DNA binding activity. The gene is associated with drought and salt tolerance, and with upregulation of wax and cutin anabolism, very-long-chain fatty acid metabolism, and cuticle anabolism. It is linked to cell wall modification, xyloglucan metabolism, defence response to Gram-negative bacteria, and cellular response to auxin stimulus. Associations with agronomic traits include grain volume, grain width, test weight, grain yield per plant, harvest index, heading time, floret number, spikelet number, flag leaf angle, plant vegetative period, frost damage, stem rust, and bread loaf volume. The gene is also connected to phosphorus concentration, nitrate transport, and hybrid incompatibility. Related genes in other species are linked to naked caryopsis phenotype.
