Abstract

Nucleotide sequences of complete or partial coat protein (CP) genes were determined for 11 isolates of pea seed-borne mosaic virus (PSbMV) from Australia and one from China, and compared with known sequences of 20 other isolates. On phylogenetic analysis, the isolates from Australia and China grouped into 2 of 3 clades. Clade A contained three sub-clades (Ai, Aii and Aiii), Australian isolates were in Ai or Aiii, and the Chinese isolate in Aii. Clade A contained isolates in pathotypes P-1, P-2 and U-2; clade B, one isolate in P-2; and clade C, only isolates in P-4.
