A novel plant transposon that induces bud mutation, transposase thereof, and a method for efficiently inducing bud mutation by improvement in the transposition efficiency are provided. A novel transposon having terminal inverted repeat sequences (SEQ ID NO: 1 and SEQ ID NO: 2) shown below has been isolated for the first time from carnation () and the nucleotide sequence thereof has been determined. The transposon has contained a gene encoding the transposase in its sequence. The transposon induces bud mutation when it is inserted into a gene. The transposition frequency is elevated due to environmental stress. TAGAGCTGGCAAA---TTTGCCAGCTCTA (SEQ ID NOS 1 & 2, respectively in order of appearance).
