PINB — Triticum turgidum subsp. durum

Summary

TRITD5BV1G000590 (symbol PINB) on durum wheat chromosome 5B encodes a protein belonging to the Glia_glutenin family and the bifunctional inhibitor/lipid transfer protein/seed storage helical domain superfamily. The gene product exhibits toxin activity, serine-type endopeptidase inhibitor activity, and nutrient reservoir activity. It is associated with defence response to bacteria and localises to the extracellular region and membrane. PINB is linked to grain texture, grain weight, and protein content. Studies of related genes in other species connect the family to a wide range of seed and agronomic traits, including seed hardness, flour yield, starch digestibility, grain size, test weight, seed protein content, germination rate, and drought tolerance.
