Characterization of Hawaiian isolates of Cymbidium mosaic virus (CymMV) co-infecting Dendrobium orchid
Abstract
We report here the isolation and characterization of three distinct isolates of Cymbidium mosaic virus (CymMV) co-infecting Dendrobium orchid in Hawaii. Isolates 1 and 2 were phylogenetically distinct from previously reported CymMV isolates. However, isolate 3 was highly similar to previously reported CymMV sequences and could be localised to CymMV subgroup A. Isolate 2 localised to CymMV subgroup B. Thus, we report here the first full-length CymMV subgroup B isolate. Isolate 1 represents a recombination event between isolates 2 and 3. Infectivity assays revealed that all three isolates are functional and individually infectious in both Dendrobium and indicator species.
