Abstract:
The genome of a potyvirus (isolate JaVT_FZ) recovered from jasmine (Jasminum sambac L.) showing yellow ringspot symptoms in Fuzhou, China, was sequenced. JaVT_FZ is closely related to seven other potyviruses with completely sequenced genomes, with which it shares 66-70 % nucleotide and 52-56 % amino acid sequence identity. However, the coat protein (CP) gene shares 82-92 % nucleotide and 90-97 % amino acid sequence identity with those of two partially sequenced potyviruses, named jasmine potyvirus T (JaVT-jasmine) and jasmine yellow mosaic potyvirus (JaYMV-India), respectively. This suggests that JaVT_FZ, JaVT-jasmine and JaYMV-India should be regarded as members of a single potyvirus species, for which the name "Jasmine virus T" has priority.
