The present invention provides a method for conferring tolerance to an amino acid analog of tryptophan to a plant and/or altering the tryptophan content of a plant by introducing and expressing an isolated DNA segment encoding an anthranilate synthase in the cells of the plant. Transgenic plants transformed with an isolated DNA segment encoding an anthranilate synthase, as well as seeds and progeny derived from these plants, are also provided. The present invention also provides a cDNA sequence of an alpha and a beta subunit of a maize anthranilate synthase.
L'invention porte sur un procédé rendant une plante tolérante vis à vis d'un analogue d'acide aminé, de la tryptophane et/ou en modifiant la teneur en tryptophane, par l'introduction et l'expression dans ses cellules d'un segment isolé d'ADN codant pour une anthranilate synthase. L'invention porte également sur les plantes transgéniques ainsi obtenues et sur leurs graines et leur lignée; elle porte en outre sur une séquence d'ADNc des sous-unité alpha et bêta d'une anthranilate synthase du maïs.
