| Abstract: | The complete coat protein (CP) nucleotide sequences of 13 Potato virus S (PVS) isolates from Australia and three from Europe were compared to those of 37 others. On phylogenetic analysis, the Australian
sequences were in PVSO sub-clades III and IV, and the European isolates were in sub-clades I and VII. The European isolates invaded Chenopodium spp. systemically, but eight Australian isolates did not. Amino acid sequence differences at the N-terminal ends of the CPs
were unrelated to the ability to invade Chenopodium spp. systemically. The acronym PVSO–CS is suggested for isolates that invade Chenopodium spp. systemically but are not within clade PVSA. |
