Pepino mosaic virus (PepMV), a previously undescribed virus, was found in fields of pepino in the Canete valley in coastal Peru and its properties are typical of the potexvirus group.

Nucleotide sequences appear to be remarkably stable within each of the two strain groups of BNYVV, and the amino acid changes in the coat protein area are outside the four previously determined antigenic regions that are accessible on the surface of the virus particles and are involved in the formation of continuous and presumably also discontinuous epitopes.

Nucleotide sequence analyses revealed that the genomes of the various European types of Beet necrotic yellow vein virus (BNYVV) are strongly conserved, in contrast to a pronounced sequence variability observed with Beet soil-borne pomovirus, another Polymyxa-transmitted sugar beet virus with rod-shaped particles.

A fifth beet necrotic yellow vein virus (BNYVV) RNA species has been detected in Europe in sugarbeet infected with P-type B NYVV and its proteins share a stretch of six amino acids (FRGPGN) with the BnyVV RNA 3-encoded 25K protein which may be of interest in view of the reported interactions between the two RNAs in pathogenicity.
Genome properties of beet virus Q, a new furo-like virus from sugarbeet, determined from unpurified virus.

Be beet virus Q belongs to the recently proposed genus Pomovirus; it shows evolutionary relationships to furoviruses in sensu stricto, peclu-, hordei-, tobra-, tymo-, tobamo-, carla- and potexviruses.
Beet soil-borne virus RNA 2: similarities and dissimilarities to the coat protein gene-carrying RNAs of other furoviruses.
