Evolutionary timescale and geographical movement of Cucumber mosaic virus, with focus on Iranian strains
Archives of Virology 165 (1), 185-192
Abstract: Cucumber mosaic virus (CMV) is a geographically widespread plant virus with a very broad host range. The virus has been detected in diverse crops all over Iran. In this study, we estimated the timescale of the evolution of CMV subgroup I and the geographical movement of the virus with a focus on Iranian strains. Analyses using the MP and CP genes and their concatenation revealed that the CMV population within subgroup I had a single ancestor dating back to about 450-550 years ago. The Iranian strains formed three clusters in a maximum-clade-credibility phylogenetic tree. It was found that the most recent common ancestor of the Iranian strains within each cluster dates back to less than 100 years ago. Our results also suggest that both short- and long-distance migration of Iranian CMV strains has occurred in the last 100 years.
