IRT1 — Beta vulgaris subsp. vulgaris

Summary

BvIRT1 (BVRB_8G183310) on sugar beet chromosome 8 encodes a ZIP family metal transporter with zinc ion transmembrane transporter activity. The gene is associated with iron acquisition, accumulation, and uptake in this species, as well as with zinc transport, cadmium transport, detoxification, homeostasis, and cell death. It is linked to iron uptake and transport in root vascular system, import of Fe(II) from extracellular space to phloem cells, and response to iron deficiency. The product localizes to the plasmalemma. Related genes in other species are linked to iron concentration traits and zinc uptake.
