8.A.20.1.1









WR3; wound responsive protein-3 or NAR2.1, an accessory protein for transport via 2.A.1.8.12 (Yong et al., 2010). May act as a dual component transporter with NTR2.1; required for high-affinity nitrate transport. Acts as a repressor of lateral root initiation. May be involved in targeting NRT2 proteins to the plasma membrane.
