The present invention provides a genetically modified plant that biosynthesizes an increased amount of capsinoids, a method of producing the genetically modified plant, and a production method of capsinoids from the genetically modified plant. More particularly, the present invention provides a genetically modified plant capable of producing capsinoids, which shows a decreased expression or activity of an enzyme that catalyzes an amino group conversion reaction from vanillin to vanillylamine as compared to wild strains, and the like. As a method of suppressing expression or activity of an enzyme, an introduction of DNA encoding an antisense RNA, iRNA, ribozyme or dominant-negative mutant for the target gene, a destruction of the gene by a knockout method, mutagen treatment or transposon insertion, an introduction of a gene encoding an antibody against the enzyme and the like can be mentioned.
