Characterization of the amino acid transporter AAP1 in Arabidopsis thaliana
… confirmed to affect the amino acid transporter AAP1. Here I demonstrate that, when expressed in yeast deficient for endogenous amino acid transporters, three variant aap1 proteins restored growth similar to yeast complemented by wild type AAP1. Transport of radiolabeled Pro was abolished by …

Characterizing the role in amino acid sensing and signaling of Amino Acid Permease 1 in Arabidopsis
… identified in plants. Amino Acid Permease 1 (AAP1) has been previously characterized and was shown to mediate amino acid uptake from the soil. aap1 knockout plants and several EMS mutants affected in AAP1 sequence display enhanced tolerance to toxic concentrations of amino acids. Yet, two of …

Molecular and Genomic Analysis of Nitrogen Regulation of Amino Acid Permease I (Aap1) in Arabidopsis
… regulating expression of amino acid transporter AAP1, this may lead to modulated phloem loading of amino acids and finally influence plant nitrogen status.

NAT2/AAP1 as a Prototypical Example of the AAP Amino Acid Transporter Gene Family: From Protein Topology to Regulation of Gene Expression
A genomic clone of NAT2 was isolated and sequenced. The 5' -flanking region contains several consensus recognition sites for putative transcription factors. I have now shown that NAT2 expression is nitrate and light inducible, but not circadian-regulated. Since the nitrate assimilatory enzymes are …
