BAM1 — Cucumis sativus

Summary

CsBAM1 (CSA_7G044880) on cucumber chromosome 7 encodes a beta-amylase (EC 3.2.1.2) with DNA-binding transcription factor activity and protein-binding capacity. It is associated with carbohydrate and maltose anabolism, polysaccharide breakdown, carotenoid and ascorbate-glutathione cycle processes, photoperiodism, fruit development, seed germination, and response to herbivores. The gene is linked to traits including percent germination, seedling vigor, photosynthetic rate, chlorophyll and carotene content, abscisic acid and sucrose content, respiration rate, and nitrogen content. Phenotypic associations include leaf starch degradation, shoot apical meristem size, stem cell specification, anther development, male fertility, heat stress tolerance, disease resistance, and root meristem development. Related genes in other species link the family to starch metabolism, shoot apical meristem maintenance, and cold tolerance.
