具有甲基转移酶活性的遗传序列及其用途

Genetic sequences having methyltransferase activity and uses therefor
摘要：
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-methyl-transferase 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.
摘要（中）：

本发明一般涉及编码具有甲基转移酶活性的多肽的遗传序列，以及遗传序列和/或多肽修饰植物的一种或多种表型特征的用途。 更具体地，本发明的甲基转移酶作用于黄酮类化合物，优选其中类黄酮是花青素。 更具体地，本发明涉及具有S-腺苷-L-甲硫氨酸：花青素3'-O-甲基转移酶或S-腺苷-L-甲硫氨酸：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编码具有衍生自矮牵牛属，Torenia Fuchsia或Plumbago或植物相关植物的甲基转移酶活性的多肽的遗传序列。 本发明还涉及对应于全部或部分受试者遗传序列以及转基因植物以及来自这些植物的切花，部分，提取物和生殖组织的反义和有义分子。
