Abstract:
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.
