Ryu, K.H. | Park, W.M.
The complete nucleotide sequence of the genomic RNA of odontoglossum ringspot tobamovirus (ORSV) was determined. The RNA genome of ORSV is 6618 nucleotides long and contains five open reading frames (ORFs 1 to 5) coding for proteins of Mr 126 K, 181K, 34K, 18K and 52K, respectively. This is the longest RNA of the known viruses of the Tobamovirus genus. The sequences of the ORSV RNA encoded proteins exhibit high homology to the proteins of the members of the Tobamovirus genus. The genomic organization and sequence analysis showed that ORSV is more closely related to tobacco mild green mosaic virus (TMGMV), pepper mild mottle virus (PMMV), tomato mosaic virus (ToMV) and TMV than to cucumber green mottle mosaic virus (CGMMV) and sunn-hemp mosaic virus (SHMV).
