General Information

EC Number General Information Comment Organism
7.4.2.1 physiological function when expressed in yeast, LHT1 supports cell growth on a broad spectrum of amino acids, and effectively transports aspartate, asparagine and glutamate. Knockout of LHT1 in subsp. japonica results in reduced root uptake of amino acids. In 15N-amino acid-fed mutants versus wild-type, a higher percentage of 15N remains in roots instead of being allocated to the shoot. 15N-ammonium uptake and subsequently the delivery of root-synthesized amino acids to LHT1 mutant shoots are also significantly decreased Oryza sativa Japonica Group
