WALI6 — Triticum aestivum

Summary

TRAESCS1B02G276900 (WALI6) on bread wheat chromosome 1B encodes a serine-type endopeptidase inhibitor belonging to the Bowman-Birk inhibitor (BBI) family. The gene is associated with salt acclimation in wheat, and has been linked to proline content, stripe rust, and cold tolerance. Annotated biological processes include signaling, glycan biosynthesis, and embryogenesis, and the protein is predicted to localize to the extracellular space. The gene is also connected to regulatory networks involved in salinity response, submergence response, and photoperiod-regulated flowering. Studies of related Bowman-Birk serine protease inhibitors in other species link the family to stress-responsive functions, though these associations are not yet established for WALI6 itself.
