WR3 — Lactuca sativa

Summary

LsWR3, encoded by the gene LSAT_V11C400187970 on chromosome 4 of garden lettuce (Lactuca sativa), is a member of the Transptr_NO3_Nar2 family and possesses nitrate transmembrane transporter activity. The gene is associated with nitrate transmembrane transport, cellular response to nitrate, nitrate assimilation, and response to wounding, and its product localizes to the membrane and plasmalemma. LsWR3 has been linked to a wide range of agronomically important traits, including nitrogen and nitrate sensitivity, biomass yield, seed yield, root development and hair length, flowering time, anthocyanin content, drought tolerance, and disease tolerance. Studies of related genes in other species connect the family to high-affinity nitrate uptake and transport, and to disease resistance.
