HMA1 — Beta vulgaris subsp. vulgaris

Summary

BvHMA1 (BVRB_2G033820) on sugar beet chromosome 2 encodes a P-type ATPase with heavy-metal-associated domains, annotated as a copper, zinc and cadmium transporter. The gene is associated with detoxification of zinc, copper and cadmium ions, metal ion transport, proton export across the plasma membrane, cell pH regulation, and regulation of root morphogenesis. It is linked to traits including copper sensitivity, drought tolerance, high-temperature stress response, oxidative stress response, bacterial disease response, leaf senescence, flowering time, germination rate, nitrate uptake, and stomatal opening and closure. Related genes in other species are associated with chloroplast copper delivery, photosensitivity under high light, the water-water cycle of photosynthesis, and cadmium and zinc partitioning and translocation.
