A proposal to help resolve the disagreement between naming of potato virus Y strain groups defined by resistance phenotypes and those defined by sequencing

Abstract

The complete coat protein (CP) nucleotide sequences of nine historical (1943-1984) potato virus Y (PVY) isolates belonging to resistance strain groupings YC, YZ or YO, and nine new Australian isolates from potato and tomato were compared with those of 85 others. New potato isolate BL was in resistance group YO. On phylogenetic analysis, the historical potato isolates fitted within phylogenetic groups C1 or C2 (YC), ‘YO’ (YZ, YO) or N-Wi (YZ), while the new isolates were in phylogenetic groups C1 (tomato) or ‘YO’ (potato, tomato). Substitution of the designation (YQ) for the current phylogenetic ‘YO’ grouping is proposed for consideration.
