Abstract
A viable strain of cauliflower mosaic virus is described which arose by illegitimate recombination of two lethal parents. In this strain, the normally overlapping open reading frames IV and V, corresponding to the retrovirus gag and pol genes, are separated by a short intergenic region, suggesting that in this virus and in contrast to retroviruses, fusion of gag and pol gene products is not obligatory.
摘要
描述了一种花椰菜花叶病毒的存活株系，它由两个致死亲本通过异常重组产生。在该株系中，通常重叠的开放阅读框IV和V（分别对应逆转录病毒的gag和pol基因）被一个短的基因间隔区隔开，这表明在这种病毒中，与逆转录病毒不同，gag和pol基因产物的融合并非是必需的。
