DNAs coding for flavone synthases, methods of using flavone synthase DNAs, and plants, flowers, and vectors containing flavone synthase DNAs

摘要

DNA obtained, for example, from snapdragon or torenia, encoding an enzyme that can convert flavanones directly to flavones, and its uses; the DNA and amino acid sequences for enzymes encoded thereby are listed as SEQ. ID. No. 1 & 2 and 3 & 4, for example. Introduction of the genes into plants can, for example, alter the flower colors of the plants.
