title: Biological variability of potyviruses, an example: zucchini yellow mosaic virus.
abstract: Potyviruses present an important variability which may affect biological properties such as host range, symptomatology, virulence towards resistance genes, and transmissibility by vectors. A brief account of this potential is presented and illustrated by some aspects of the biological variability of zucchini yellow mosaic virus (ZYMV).
