AMO — Beta vulgaris subsp. vulgaris

Summary

BvAMO (BVRB_005510) in sugar beet encodes a copper amine oxidase with putrescine oxidase, diamine oxidase, aliphatic amine oxidase, and primary methylamine oxidase activities, along with quinone and copper binding and protein homodimerization. This gene is associated with putrescine breakdown, amine metabolism, nitrogen utilization, protoxylem development, glutamate metabolism, regulation of flavonoid and alkaloid anabolism, amino acid transport, glutathione metabolism, regulation of programmed cell death, secondary cell wall biogenesis, and responses to salt, jasmonic acid, and auxin. It is linked to salt response, chlorophyll content, and the SALTTL trait. The protein localizes to the plant-type cell wall and extracellular region. Related genes in other species are linked to auxin biosynthesis and fruit development.
