Summary. We have sequenced the coat protein (CP) coding region of 11 field isolates of SCMV from Australia, USA and South Africa. The differences between the nucleotide sequences of the isolates was 0.2 to 4.1% and the encoded amino acid sequences differed by 0.0 to 3.5%. Phylogenetic analysis of the CP coding sequences of the SCMV isolates and the related potyviruses SCMV-MDB, JGMV, SrMV, MDMV-A and PVY showed that the SCMV isolates formed a tightly clustered group, with SCMV-MDB forming a separate branch. This indicated that (i) the SCMV isolates are of one strain (SCMV-A) and not geographically distinct species and (ii) SCMV-MDB is clearly distinct, and may represent another potyvirus species.
