title: Population structure of blackberry chlorotic ringspot virus in the United States.
abstract: Blackberry chlorotic ringspot virus is a subgroup 1 ilarvirus, detected in several rosaceous hosts exhibiting disease symptoms in Europe and the United States. The population structure of the virus was studied using isolates collected from wild and cultivated plants from six states in the United States. The results suggest a homogeneous virus population in the United States, similar to what observed within single orchards for other ilarviruses. Given the lack of evidence for host or geography-driven adaptation, it is hypothesized that the virus was recently introduced into the New World.
