The present invention relates generally to a genetic sequence encoding a polypeptide having methyltransferase activity and the use of the genetic sequence and/or the polypeptide to modify one or more phenotypic characteristics of a plant. More particularly, the methyltransferase of the present invention acts on flavonoids, preferably wherein the flavonoid is an anthocyanin. Even more particularly, the present invention relates to a polypeptide having S-adenosyl-L-methionine: anthocyanin 3' -O-methyltransferase or S-adenosyl-L-methionine: anthocyanin 3', 5'-O-methyltransferase activity. The present invention still further provides a genetic sequence encoding a polypeptide having methyltransferase activity derived from Petunia, Torenia Fuchsia or Plumbago or botanically related plants. The instant invention further relates to antisense and sense molecules corresponding to all or part of the subject genetic sequence as well as genetically modified plants as well as cut flowers, parts, extracts and reproductive tissue from such plants.
本发明一般涉及编码具有甲基转移酶活性的多肽的基因序列,以及利用该基因序列和/或多肽改变植物的一种或多种表型特征。更特别的是,本发明的甲基转移酶作用于类黄酮,其中类黄酮最好是花青素。更特别的是,本发明涉及一种具有 S-腺苷-L-蛋氨酸:花青素 3'-O-甲基转移酶或 S-腺苷-L-蛋氨酸:花青素 3',5'-O-甲基转移酶活性的多肽。本发明还进一步提供了一种编码具有甲基转移酶活性的多肽的基因序列,该多肽来源于矮牵牛、紫花地丁或板蓝根或植物学上相关的植物。本发明还涉及与全部或部分主题基因序列相对应的反义和有义分子,以及转基因植物和来自这些植物的切花、部分、提取物和生殖组织。
