The nucleotide sequence of a chinese isolate of wheat yellow mosaic virus and its comparison with a Japanese isolate. Brief report.
The nucleotide sequences of wheat yellow mosaic virus isolated in China were determined and compared with a Japanese isolate of the same virus. Results showed that the viral genome had 7629 nucleotides for RNA1 and 3639 nucleotides for RNA2, which shared 97. 1% and 94.6% of identities to the RNAs of Japanese isolate. The single open reading frames in RNA1 and RNA2 encoded polyproteins with 2407 amino acids and 903 amino acids respectively, from which ten proteins may be produced by autolytic cleavage processing as the Japanese isolate. Since the sequence of WYMV RNA1 showed identity of less than 70% with that of WSSMV, it is further confirmed that WYMV is a distinct species within Bymovirus.
