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.
摘要:
The present invention provides a protein having aurone synthase activity involved in the color of flowers such as snapdragons, a gene that encodes it, cDNA in particular, and its applications. This gene can give yellow color to the flowers of plants by introducing into plants deficient in chalcone isomerase and so forth and expressing.
摘要:
The present invention provides DNA sequences isolated from Perilla, Torenia, Verbena and Petunia, encoding a protein having activity that transfers a glycoside to the 5 position of a flavonoid (5GT), a host cell and plants transformed with said DNA sequences and a process for producing a protein using said DNA sequences.
