DNA AND VECTOR FOR REGULATING THE EXPRESSION OF LACHRYMATOR SYNTHASE GENE, METHOD OF REGULATING THE EXPRESSION OF LACHRYMATOR SYNTHASE GENE USING THE SAME, AND PLANT WITH THE REGULATED EXPRESSION OF LACHRYMATOR SYNTHASE GENE

摘要

A DNA encoding a protein or polypeptide with an effect of converting 1-propenylsulfenic acid into a lachrymator, is new. Independent claims are also included for: (1) a primer for isolating the lachrymator synthase gene of a plant belonging to genus Allium, which contains a sequence of (XXV) comprising 26 base pairs; (2) isolating the Allium lachrymator synthase gene by using the primer; (3) a recombinant vector containing any of the DNAs; (4) a transformant containing the recombinant vector; (5) producing the protein or polypeptide with lachrymator synthase activity; (6) a protein or polypeptide with lachrymator synthase activity containing: (a) an amino acid sequence of (II), (VI), (VIII), (X), (XIV) or (XVI) comprising 164-169 amino acids; (b) an amino acid sequence based on the sequence of (II), (VI), (VIII), (X), (XIV) or (XVI) but with some amino acids added, deleted or substituted; or (c) an amino acid sequence comprising 65 % homology with the sequence of (II), (VI), (VIII), (X), (XIV) or (XVI); and (7) a nucleic acid molecule with a function of inhibiting the translation of mRNA concerning the protein or polypeptide. ACTIVITY : Ophthalmological. No biological data given. MECHANISM OF ACTION : None given.
