VIT1 — Phaseolus vulgaris

Summary

PHAVU_002G322900, designated PvVIT1, encodes a member of the Ccc1 family with iron channel activity, manganese ion transmembrane transporter activity, and DNA-binding transcription factor activity. It is associated with cellular and multicellular iron and manganese ion homeostasis, iron transport, vacuolar membrane and nuclear localization, and processes including cell wall modification, meristem structural organization, and maintenance of floral meristem identity. The gene is linked to traits such as zinc concentration, flowering time, photoperiod-sensitive flowering, and seed growth and development, as well as phenotypes including iron accumulation, vacuolar storage, and distribution in seeds. Related genes in other species are linked to vacuolar iron transport, iron homeostasis, and iron storage and distribution in seeds.
