AMY1 — Phaseolus vulgaris

Summary

PHAVU_010G017600, designated AMY1 or PvAMY1 in French bean (Phaseolus vulgaris) on chromosome 10, encodes an alpha-amylase enzyme with alpha-amylase activity and calcium ion binding, belonging to the GH13 catalytic domain and glycosyl hydrolase superfamily. This gene is associated with sucrose breakdown, carbohydrate metabolism, and responses to gibberellin, abscisic acid, and defense responses. The product localizes to the apoplast and extracellular space. AMY1 is associated with starch degradation and stress response. Related genes in other species are linked to starch breakdown, flowering time, salt response, and flowering time traits.
