C. de  aDistinct levels of relationship between tospovirus isolates.h[electronic resource]  c1993  aThe taxonomic relations of a number of tospovirus isolates, collected in different geographical areas and from different host plants, were studied. To delineate these isolates, properties such as susceptibility of a limited range of host plants, symptomatology, cytopathology, nucleocapsid composition, serology of their nucleocapsid proteins, and nucleotide sequence homology were compared. The results show that isolates which have previously been discriminated as members of three different serogroups, should in fact be regarded as representatives of at least three distinct virus species in the tospovirus genus.  ataxonomy  aTospovirus  aTaxonomia  aVírus1 aHAAN, P. de1 aSMEETS, M.
