PINB — Triticum turgidum subsp. durum

Summary

TRITD7BV1G218460 (symbol PINB) on durum wheat chromosome 7B encodes a bifunctional inhibitor/plant lipid transfer protein/seed storage helical domain-containing protein with serine-type endopeptidase inhibitor activity, nutrient reservoir activity, and toxin activity. The gene is associated with defence response to bacteria and localises to the extracellular region and membrane. PINB is associated with kernel hardness, grain texture, grain weight, and protein content. Studies of related genes in other species connect this gene family to grain hardness, seed vitreousness, flour yield, starch digestibility, sprouting tolerance, test weight, grain width, seed protein content, and seed maturation.
