摘要： The present invention provides a simple aneuploid production process, applicable to all species, without producing unexpected damage to chromosomes other than a chromosome which is to be disappeared. A vector comprising two site-specific recognition sequences oriented in the opposite direction, or one site-specific recombinase recognition sequence comprising a point-symmetric nucleotide sequence, and a recombinase gene is introduced into a plant cells or a vector comprising two site-specific recognition sequences oriented in the opposite directions or one site-specific recombinase recognition sequence comprising a point-symmetric nucleotide sequence is introduced into a plant cell; a recombinase is allowed to act transiently in the cell during at least growth of the cell; and the cell is cultured and grown; and a cell in which a predetermined chromosome is disappeared is selected.

摘要： In order to provide a vector and a method for introducing one copy of a desired gene to a predetermined position of a host DNA at a high frequency without any bad influences upon the host cell and a vector and a method for deleting or inverting a host DNA at a predetermined position without a crossing step and without any bad influences upon the host cell. A vector which has an introduction cassette inserted between two site-specific recombinase recognition sequences and a site-specific recombinase gene which recognizes these site-specific recombinase recognition sequences, wherein the recombinase gene is positioned outside the introduction cassette, is used, and this is introduced into a host cell having a DNA in which one or two site-specific recombinase recognition sequences are present. A recombinant of interest can be efficiently obtained by positioning a lethal induction gene or a morphological abnormality induction gene outside the introduction cassette, together with the site-specific recombinase gene.
