BAM1 — Triticum aestivum

Summary

TRAESCS5A02G554200, designated TaBAM1 on bread wheat chromosome 5A, encodes a beta-amylase (EC 3.2.1.2) belonging to the glycoside hydrolase family 14. The gene is associated with starch breakdown, polysaccharide breakdown, and glucan anabolism, as well as with pre-harvest sprouting. TaBAM1 has been linked to grain weight per spike, grain yield per plant, seed weight, test weight, flour protein content, amylose content, grain iron and zinc content, and harvest index. It is also associated with drought sensitivity and stem rust, along with vasculature development, flag leaf senescence, and grain filling period. Studies of related genes in other species link the family to cold temperature responses.
