摘要：
The present invention relates to a method for obtaining a transformed Ipomoea batatas plant body having high accumulations of carotenoid and anthocyanin by transforming a recombinant vector, which includes an IbOr-Ins gene mutation obtained by artificially inserting a specific base sequence into an IbOrange gene derived from Ipomoea batatas, into an Ipomoea batatas plant body accumulating anthocyanin. The present invention further relates to a transformed Ipomoea batatas plant body including highly accumulated carotenoid and anthocyanin obtained by the method, and to seeds thereof. The present invention further relates to a method for obtaining a transformed Ipomoea batatas plant body including highly accumulated anthocyanin and having increased resistance to environmental stress compared to a wild plant body by transforming the recombinant vector into an Ipomoea batatas plant body accumulating anthocyanin, to a transformed Ipomoea batatas plant body including highly accumulated anthocyanin obtained by the method and having increased resistance to environmental stress compared to a wild plant body, and to seeds thereof. The present invention further relates to an amount of carotenoid in the Ipomoea batatas plant body accumulating anthocyanin and including the IbOr-Ins gene mutation, and to a composition for increasing resistance to environmental stress.La présente invention concerne un procédé dobtention dun corps végétal transformé dIpomoea batatas ayant des accumulations élevées de caroténoïde et danthocyanine, par la transformation dun vecteur recombinant qui comprend une mutation du gène IbOr-Ins obtenue par linsertion artificielle dune séquence spécifique de bases dans un gène IbOrange issu dIpomoea batatas à lintérieur dun corps végétal dIpomoea batatas accumulant de lanthocyanine. La présente invention concerne en outre un corps végétal transformé dIpomoea batatas comprenant un caroténoïde et de lanthocyanine fortement accumulés obtenu par le procédé, et des
