List of plant viruses
The taxonomy of plant viruses includes all virus families and genera together, where plant pathogenic viruses ( plant viruses are) represented. It follows the principles of virus taxonomy , according to which the main taxonomic distinguishing features are the presence of a virus envelope , the symmetry of the capsid and the type of genome . The nucleic acid that forms the genome in the virion can consist of RNA or DNA, each as a single strand ( linear ), covalently closed to form a circle ( circular ) or in several pieces ( segmented); the nucleic acid can be single-stranded ( single-stranded, ss ) or double-stranded ( double-stranded, ds ). According to the polarity of a single-stranded nucleic acid, a distinction is made between negative ss (-), positive ss (+) and ambisense ss (- / +) genomes. With some plant viruses, RNA is transcribed into DNA by reverse transcriptase (RT) during reproduction .
The majority of the families listed contain exclusively plant viruses, only three families also include genera with animal viruses ( Reoviridae , Rhabdoviridae , Bunyaviridae ). Many genera of plant viruses are not yet assigned to a family according to the ICTV specifications (not classified, nk).
