Abstract: According to the present invention, the polypeptide of theobromine synthase derived from coffea arabica and the gene encoding said polypeptide are provided. As theobromine synthase participates in biosynthesis of caffeine, caffeineless coffee would be obtained by preparing a transformed plant, wherein expression of gene encoding said enzyme is inhibited.
