Transporters in Arabidopsis roots mediating uptake of amino acids at naturally occurring concentrations

Sammanfattning

We conclude that LHT1 and AAP5, but not AAP1, are crucial for amino acid uptake at concentrations typically found in soils. LHT1 and AAP5 displayed complementary affinity spectra, and no redundancy with respect to gene expression was found between the two transporters, suggesting these two transporters have separate roles in amino acid uptake.

Nyckelord

amino acid permease 1 (AAP1); amino acid permease 5 (AAP5); kinetics; lysine histidine transporter 1 (LHT1); mutants
