VIT1 — Triticum aestivum
Summary
TRAESCS5B02G202100 (TaVIT1, also known as TaVIT2-5B) on wheat chromosome 5B encodes a member of the Ccc1 family. The protein exhibits iron ion sequestering activity, manganese ion transmembrane transporter activity, and iron channel activity, and is localized to the vacuolar membrane and nucleus. TaVIT1 is associated with cellular and multicellular iron and manganese ion homeostasis, iron transport, and maintenance of floral meristem identity. The gene has been linked to grain weight, heading time, plant height, flag leaf angle, photosynthetic rate, and seed growth and development traits. It is also connected to responses to abiotic stimuli, including drought escape pathways and circadian rhythm. Studies of related genes in other species link the family to vacuolar iron storage and seed iron distribution, grain yield, and zinc concentration.
