Lychnis mottle virus (LycMoV), family Secoviridae, is one of several viruses recently detected in peony. Given the high prevalence of the virus in the more than 300 samples tested, the population structure of the virus was studied using 48 isolates representing at least 20 cultivars and collected from major producing and propagating states in the United States. The homogeneity of the United States population, based on data from the RNA2 coding region, along with phylogenetic analyses of all publicly available sequences point to the dissemination of the virus through propagation material rather that active vector-mediated transmission.

基于 RNA2 编码序列的西科病毒斑驳病毒种群结构

Lychnis 斑驳病毒 (LycMoV) 是 Secoviridae 家族，是最近在牡丹中发现的几种病毒之一。鉴于该病毒在 300 多个测试样本中的高流行率，使用代表至少 20 个栽培品种的 48 个分离株研究了该病毒的种群结构，并从美国的主要生产和传播州收集。根据来自 RNA2 编码区的数据，以及对所有公开可用序列的系统发育分析，美国人口的同质性表明病毒通过传播材料传播，而不是通过主动载体介导的传播。
