The population structure of blueberry mosaic associated virus (BlMaV), a putative member of the family Ophioviridae, was examined using 61 isolates collected from North America and Slovenia. The studied isolates displayed low diversity in the movement and nucleocapsid proteins and low ratios of non-synonymous to synonymous nucleotide substitutions, indicative of strong purifying selection. Phylogenetic analyses revealed grouping primarily based on geography with some isolates deviating from this rule. Phylogenetic incongruence in the two regions, coupled with detection of reassortment events, indicated the possible role of genetic exchange in the evolution of BlMaV.
采用来自北美和斯洛文尼亚的 61 个分离物,对蓝莓斑驳病毒(BlMaV)的种群结构进行了研究,该病毒是蛇形病毒科的一个假定成员。研究的分离物在运动和核衣壳蛋白中显示出低多样性,非同义核苷酸取代与同义核苷酸取代的比值低,表明存在强烈的纯化选择。系统发育分析主要基于地理分组,但有些分离物偏离了这一规则。两个区域的系统发育不一致,加上重组事件的检测,表明遗传交换可能在 BlMaV 的进化中起作用。
