Abstract

We tested citrus samples from Japan using reverse transcription-polymerase chain reaction (RT-PCR), and for the first time, Citrus viroid V (CVd-V) was detected in Japan. Using nucleotide sequence analysis, we identified two new CVd-V variants, which shared 91–96% nucleotide sequence identities with those reported previously and 89% with each other. The RT-PCR detected CVd-V from 44 of 275 citrus trees tested, showing that CVd-V can be spread to some extent within commercial orchards in Japan.
