NTR1 encodes a high affinity oligopeptide transporter in Arabidopsis.

Hterologous complementation of yeast mutants has enabled the isolation of genes encoding several families of amino acid transporters. Among them, NTR1 codes for a membrane protein with weak histidine transport activity. However, at the sequence level, NTR1 is related to rather non-specific oligopeptide transporters from a variety of species including Arabidopsis and to the Arabidopsis nitrate transporter CHL1. A yeast mutant deficient in oligopeptide transport was constructed allowing to show that NTR1 functions as a high affinity, low specificity peptide transporter. In siliques NTR1-expression is restricted to the embryo, implicating a role in the nourishment of the developing seed.
