Title Constitutive Expression of a Novel-Type Ammonium Transporter OsAMT2 in Rice Plants.
Abstract:
To characterize ammonium transport pathways in rice, two cDNAs with high homology to MEP/AMT2-type ammonium transporters, OsAMT2;1 and OsAMT3;1, were isolated. Expression of OsAMT2;1 in an ammonium-uptake-defective yeast mutant showed that this gene encodes functional ammonium transporters. OsAMT2;1 was constitutively expressed in both roots and shoots irrespective of the supply of inorganic nitrogen to the medium, whereas OsAMT3;1 expression was relatively weak. A database search with the amino acid sequence of OsAMT2;1 showed that there are 10 putative OsAMT genes in rice, i.e. three each for OsAMT1, OsAMT2 and OsAMT3, respectively, and one for OsAMT4.
