NRT2.1 — Lactuca sativa

Summary

LSAT_V11C100025730, designated NRT2.1 on garden lettuce (Lactuca sativa) chromosome 1, encodes a protein belonging to the NO3_transporter and MFS_trans_sf families. The gene product is annotated with nitrate and nitrite transmembrane transporter activities and is associated with nitrate import, nitrate assimilation, nitrite transport, cellular response to nitrate, cell development, and cell wall organization. It localizes to the plasma membrane and transporter complex. NRT2.1 is linked to nitrate transport, nitrate uptake, and root hair length. Studies of related genes in other species, including NRT2.2, NRT2.3, NAR3, and NAR4, connect the family to high-affinity nitrate transport systems.
