MFS1 — Triticum aestivum

Summary

TaMFS1 (TRAESCS5D02G334500) on wheat chromosome 5D encodes a major facilitator superfamily (MFS) transporter with a nodulin-like domain. The gene is associated with grain weight, grain length, grains per spike, grain number, and grain yield, as well as plant height and shoot fresh weight. It is linked to auxin content, responses to karrikin, nitrate, jasmonic acid, and ethylene, and processes including transition metal and calcium transport, proton transmembrane transport, vacuole organization, protein membrane targeting, positive regulation of flavonoid anabolism, and regulation of the hypersensitive response. The encoded protein localizes to the membrane and plasmalemma. Studies of related genes in other species connect the MFS transporter family to seed germination, drought tolerance, starch mobilization, and lignin content.
