Abstract
This invention relates to an isolated nucleic acid fragments encoding an ammonium transporter. The invention also relates to the construction of a recombinant DNA construct encoding all or a portion of ammonium transporters, in sense or antisense orientation, wherein expression of the recombinant DNA construct may alter levels of the ammonium transporter in a transformed host cell.
Claims10
An isolated polynucleotide comprising:
- (a) a nucleotide sequence encoding a polypeptide having ammonium transporter activity, wherein the amino acid sequence of the polypeptide and the amino acid sequence of SEQ ID NO:16 have at least 95% sequence identity based on the Clustal alignment method, or
- (b) the complement of the nucleotide sequence, wherein the complement and the nucleotide sequence contain the same number of nucleotides and are 100% complementary.
