Rice ornithine carbamyltransferase gene, and a vector containing said gene and a transformant

摘要

An object of the present invention is to isolate complementary DNA coding for ornithine carbamyltransferase derived from a rice plant, necessary for development of a plant ornithine carbamyltransferase gene mutated to have phaseolotoxin resistance, and further to establish an expression system in microorganisms for simply evaluating the functions of the gene mutated to have resistance. This object is solved by a rice ornithine carbamyltransferase gene coding for a protein consisting of the amino acid sequence shown in SEQ ID NO:6 in the Sequence Listing, a plasmid vector containing the gene, and a transformant carrying the plasmid vector.
