Publication number: 20050009165Abstract: Raffinose synthase purified from cucumber is allowed to act on sucrose and galactinol. Thus raffinose is efficiently produced. The function of endogenous raffinose synthase is regulated by transforming a plant with a chimeric gene comprising a raffinose synthase gene and a regulatory region expressible in the plant. Thus a plant, in which raffinose family oligosaccharides are decreased, is created.Type: ApplicationFiled: August 20, 2004Publication date: January 13, 2005Applicant: AJINOMOTO CO.
