  • Patent number: 11464182
    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.

  • Publication number: 20190221283
    Abstract: With the use of nucleotide sequence data concerning transcription products, transcriptome analysis is performed with higher precision. Concerning a plurality of data sets including the objective variable data and the gene expression level data, a plurality of subdata sets are generated by randomly deleting the gene expression level data, and the method of regularization is applied to the plurality of subdata sets to calculate relevant estimation formulae and then generate the lists of genes included in the estimation formula.
