Comparisons of complete RNA-2 sequences, pathological and serological features among three Japanese isolates of Arabis mosaic virus.

Arabis mosaic virus lily and narcissus isolates (ArMV-Li and ArMV-Na) induced severe necrotic spots on Chenopodium quinoa, whereas ArMV butterbur isolate (ArMV-Bu) caused symptomless infection in the plant. The accumulation level of ArMV-Bu in upper non-inoculated leaves of C. quinoa was comparable to that of ArMV-Li or -Na.
