In four distinct alstroemeria-infecting cucumber mosaic virus (CMV) isolates, additional sequences of various lengths were present in the 3' nontranslated regions of their RNAs 2 and 3, apparently the result of intra- and intermolecular recombination events. Competition experiments revealed that these recombined RNA 2 and 3 segments increased the biological fitness of CMV in alstroemeria.
在四种不同的感染六出花的黄瓜花叶病毒(CMV)分离株中,其RNA 2和RNA 3的3'非翻译区存在各种长度的额外序列,这显然是分子内和分子间重组事件的结果。竞争实验表明,这些重组的RNA 2和RNA 3片段提高了CMV在六出花中的生物学适应性。
