PINB — Triticum turgidum subsp. durum

Summary

TRITD5AV1G000200 (symbol PINB) on durum wheat chromosome 5A encodes a protein with Glia_glutenin, bifunctional inhibitor/lipid transfer/seed storage, and bifunctional inhibitor/lipid transfer/seed storage superfamily domains, annotated 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. In durum wheat, PINB is linked to grain weight and protein content, as well as grain texture. Studies of related genes in other species connect the family to seed hardness, vitreousness, flour and starch yield, grain size and thickness, test weight, seed protein and starch content, germination rate, seed maturation, sprouting tolerance, drought tolerance, and stomatal resistance.
