ABSTRACT:
DNA obtained, for example, from snapdragon ortorenia, 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.
