  • Gene encoding a protein having acyl group transfer activity
    Patent number: 7105719
    Abstract: The invention relates to isolated polynucleotides encoding a protein having aromatic acyltransferase activity, vectors comprising aromatic acyltransferase polynucleotides, and methods of transforming plants with anthocyanin acyltransferase polynucleotides to alter flower colors. The invention also relates to transformed host cells, plants, and flower cuts expressing proteins having anthocyanin acyltransferase activity.
    Type: Grant
    Filed: February 16, 1996
    Date of Patent: September 12, 2006

  • Gene encoding a protein having aurone synthesis activity
    Publication number: 20060020123
    Abstract: 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.

  • Genes coding for a protein having a glycoside transfer activity
    Publication number: 20050257291
    Abstract: The present invention provides a gene that codes for a protein having an amino acid sequence described in any of SEQ ID NOs: 7 through 10 or 12 and having activity that transfers a glycoside to the 5 position of a flavonoid, a gene that codes for a protein having a modified amino acid sequence relative to the above amino acid sequence and having activity that transfers a glycoside to the 5 position of a flavonoid, and a process for producing the above protein using said gene. This gene can be used to artificially alter the color of plants.
