Comparative studies of sequence motifs in the RNA polymerases and nucleic acid helicases of positive-sense RNA plant viruses have provided a new scheme for the classification of these pathogens. We propose a new luteovirus supergroup which should be added to the already described Sindbisvirus-like and picornavirus-like supergroups. Sequence motifs of nucleic acid helicases and RNA polymerases which previously were considered to be specific for each of the two supergroups now occur together within this new supergroup. We propose that this new viral supergroup provides an evolutionary link between the other two supergroups.
对正义RNA植物病毒的RNA聚合酶和核酸解旋酶中的序列基序进行的比较研究,为这些病原体的分类提供了新方案。我们提出一个新的黄症病毒超群,应将其添加到已描述的辛德比斯病毒样和小RNA病毒样超群中。以前被认为是两个超群中每个超群特有的核酸解旋酶和RNA聚合酶的序列基序,现在在这个新超群中同时出现。我们认为这个新的病毒超群在其他两个超群之间提供了一个进化联系。
