We obtained and cloned double stranded RNA from the only chlorotic fleck plant known to exist in the United States. The plant was infected with four closteroviruses: Strawberry chlorotic fleck associated virus, a novel member of the genus Closterovirus, Beet pseudo-yellows virus (BPYV), Strawberry pallidosis associated virus (SPaV) and a third novel member of the genus Crinivirus. The sequence obtained from the novel Crinivirus belongs to the protease domain of RNA 1. Sequence and phylogenetic analyses indicated that the novel virus is distantly related to the two viruses that can cause pallidosis disease, BPYV and SPaV. A detection protocol has been developed for the new virus and testing of plants from the East and West coasts of the United States revealed that the virus is widespread in commercial fields. Efforts are currently underway to obtain additional sequence information of the virus, identify the vector and evaluate the symptoms it causes on strawberry indicators to determine if it also is able to cause pallidosis disease. |
