    • This invention provides a method for producing a mutant virus or viroid, or a mutant recombinant RNA molecule comprising a single stranded virus genome or a single stranded viroid genome, a circular virus genome or a circular viroid genome, or a segment of a virus genome or a segment of a viroid genome which comprises incubating a recombinant single-stranded RNA molecule comprising a recognition sequence for the binding of an RNA directed RNA polymerase, a sequence for the initiation of product strand synthesis by the polymerase and a heterologous sequence of interest derived from a different RNA molecule inserted at a specific site in the internal region of the recombinant molecule under appropriate selective conditions and for a sufficient period of time permitting the selection of a mutant population, the heterologous sequence of interest comprising the RNA of the single stranded virus genome or the single stranded viroid genome, the circular virus genome or the circular viroid genome or a segment of the virus genome or a segment of the viroid genome.
    • 本发明提供了用于产生突变病毒或病毒的方法或包含单链病毒基因组或单链病毒基因组,环状病毒基因组或环状病毒基因组或病毒基因组的片段的突变型重组RNA分子或 一种病毒基因组的片段,其包括孵育包含用于RNA定向RNA聚合酶结合的识别序列的重组单链RNA分子,通过聚合酶引发产物链合成的序列和衍生自 在合适的选择性条件下插入重组分子的内部区域的特定位点的不同RNA分子,并且允许选择突变群体足够长的时间段,包含单链病毒基因组的RNA的异源感兴趣序列 或单链类病毒基因组,环状病毒基因组或环状病毒基因组 我或病毒基因组的一段或病毒基因组的片段。
