BAM1 — Hordeum vulgare subsp. vulgare
Summary
HORVU.MOREX.R3.2HG0138430 (HvBAM1) on barley chromosome 2H encodes a beta-amylase enzyme (EC 3.2.1.2) with a glycoside hydrolase family 14 domain. The gene is associated with maltose anabolism, polysaccharide breakdown, starch degradation, and starch accumulation. It has been linked to seed development, regulation of shoot development, and responses to water, cold, herbivore, and immune stimuli. Associations include grain weight, protein content, and photosynthetic rate. The product localises to the chloroplast stroma, nucleus, cytosol, endoplasmic reticulum, and extracellular space. Studies of related genes in other species link the family to starch metabolism, shoot apical meristem maintenance, and dehydration stress response.
