Abstract: A method of inducing genetic recombination, including: allowing a protein having DNA double-stranded cleavage activity to act in cells of a eukaryotic organism which is a polyploidy inherently possessed by a eukaryotic organism. In eukaryotic organisms, various genetic recombination generates new genome set composition. This is done to obtain a population of eukaryotic organisms that hold the modified genomic set.

Abstract: Provided is a genome shuffling technology suited to creating a useful next-generation plant body. Genome shuffling is performed using a polypeptide comprising a first polypeptide region for double-stranded DNA breakage activity and a second polypeptide region for intertissue migration activity.

Abstract: This invention is intended to increase biomass production through suppression of expression of a gene functioning in relation to intracellular vesicular transport or inhibition of functions of a protein encoded by such gene. To this end, expression of a gene encoding the coatomer adapter zeta subunit is suppressed, the coatomer adapter zeta subunit is inhibited, expression of a gene encoding the clathrin adaptor small (sigma) subunit is suppressed, or the clathrin adaptor small (sigma) subunit is inhibited.

Abstract: A method for producing a plant includes growing a plant from plant cells in which a promoter and a coding sequence under the control of the promoter have been artificially introduced; and selecting the plant in which an amount of phloem tissue is increased 2.0 times or more in comparison with a wild type plant of the same species. The promoter is a promoter for a gene encoding a protein having at least 60% identity with the amino acid sequence of tracheary element differentiation inhibitory factor (TDIF) receptor (TDR) of Arabidopsis thaliana. The coding sequence encodes either (i) a protein having three common sequences composed of the amino acid sequences of SEQ ID NOS: 1 to 3 in this order starting from the N-terminal side, or (ii) a protein having 95% or more identity with the amino acid sequence of SEQ ID NO:5.

Abstract: The plant is cultivated by introducing, into plant cells, a promoter specifically expressed in the vascular cambium or phloem cells of a plant, and a cell growth-promoting gene encoding a protein that promotes cell growth under the control of the promoter.
