A genome rearrangement involving RNA segment 11 of a bovine rotavirus has been analysed by molecular cloning and sequencing. This revealed that the rearranged genome segment was generated by a head to tail concatemerisation of two almost full length copies of segment 11. The upstream copy of the gene has lost its 3' end and the downstream copy its 5' end. The truncation of the upstream copy of the gene occurs within the termination codon for VP11 converting it from a UAG to a UGA, the rearranged gene is therefore still able to encode a normal VP11. The possible mechanisms by which this rearrangement may have been generated are discussed.
通过分子克隆和测序分析了涉及牛轮状病毒RNA片段11的基因组重排。这表明重排的基因组片段是由片段11的两个几乎全长拷贝的头对头串联产生的。基因的上游拷贝失去了其3'端,下游拷贝失去了其5'端。基因上游拷贝的截短发生在VP11的终止密码子内,将其从UAG转换为UGA,因此重排的基因仍然能够编码正常的VP11。讨论了这种重排可能产生的机制。
