HMA1 — Beta vulgaris subsp. vulgaris

Summary

BvHMA1 (BVRB_5G100470) on sugar beet chromosome 5 encodes a P-type ATPase with heavy-metal-associated domains, annotated with copper, zinc and cadmium transporter activities as well as histone methylase activity. The gene is associated with detoxification of copper, zinc and cadmium ions, metal ion homeostasis and transport, and responses to cobalt and toxic substances. It has been linked to traits including copper sensitivity, drought tolerance, bacterial disease response, leaf senescence, flowering time, root development, stomatal opening, and nitrate uptake. Related genes in other species connect the family to copper transport, photosensitivity under high light, the water-water cycle of photosynthesis, cadmium translocation, and zinc partitioning.
