WR3 — Lactuca sativa

Summary

LsWR3, encoded by the gene LSAT_V11C400187930 on chromosome 4 of garden lettuce (Lactuca sativa), is a protein with a Transptr_NO3_Nar2 domain and nitrate transmembrane transporter activity. It is associated with nitrate transmembrane transport, nitrate assimilation, cellular response to nitrate, response to wounding, and cell wall organization, and localizes to the membrane and plasmalemma. The gene is linked to traits including nitrogen sensitivity, biomass yield, seed yield, root development, flowering time, drought tolerance, disease tolerance, anthocyanin content, and cadmium concentration. It is also connected to phenotypes such as impaired nitrate uptake, lateral root initiation, root elongation, and pathogen resistance. Studies of related genes in other species link the family to high-affinity nitrate uptake and transport.
