PINB (TRAESCS5A02G003300) — triticum aestivum

Summary

TRAESCS5A02G003300 (PINB) on bread wheat chromosome 5A encodes a protein belonging to the Glia_glutenin and bifunctional inhibitor/lipid transfer/seed storage domain families, with annotated toxin activity, serine-type endopeptidase inhibitor activity, and nutrient reservoir activity. The gene is associated with endosperm development, pre-harvest sprouting, starch breakdown, flower development, and defence response to bacteria. It is linked to numerous grain quality and yield traits, including seed hardness, texture, vitreousness, flour yield, starch yield and digestibility, protein content, test weight, grain weight and size, and germination rate. Associations with drought tolerance and stomatal resistance are also noted. The encoded product is localised to the extracellular region and membrane. Related genes in other species link the family to grain thickness.
