A disease of borage ( Borago officinalis ) in Spain, characterized by severe mosaic and deformation of the leaves, was shown to be caused by a potyvirus. The borage‐infecting potyvirus was characterized biologically by the symptoms induced in 23 indicator species and was shown to be transmitted experimentally by the aphid Myzus persicae in a non‐persistent manner. In order to classify the borage‐infecting potyvirus we have cloned and sequenced the entire coat protein gene and 3′ non‐coding region of the viral RNA. By comparing this nucleotide sequence with those of other members of the Potyviridae , we can identify the Spanish borage‐infecting potyvirus as an isolate of clover yellow vein virus (CYVV), a virus so far only known to cause important diseases in forage legumes. This is the first record of CYVV in Spain and of CYVV infecting a natural host of the Boraginaceae.
