Abstract
Sixty-six isolates were collected during several years (1992 to 1999), along an east-west transect in a Plum pox potyvirus (PPV) focus located in southern France.
Amplification by PCR of both ends of viral coat protein genes, followed by restriction analysis, showed the existence of a PPV natural diversity with a filiation of the variants collected along the transect.
These results were confirmed by the micro-sequencing of a selected number of isolates.
These data show that an aphid transmissible virus infecting perennial woody plants can induce a sustainable local variability, particularly at the margin of an expanding focus.
