Résumé
Endogenous members of the family
Caulimoviridae
have now been found in the genomes of many plant species. Although these sequences are usually fragmented and rearranged and show varying degrees of decay, the genomes of the ancestral viruses can often be reassembled
in silico
, allowing classification within the existing viral taxonomic framework. In this paper, we describe analyses of endogenous members of the family
Caulimoviridae
in the genomes of
Oryza sativa
,
Nicotiana tabacum
and
Solanum
spp. and on the basis of phylogeny, genome organization and genetic distance within the
pol
gene, propose two new virus genera called Orendovirus and Solendovirus. A system of nomenclature for endogenous virus sequences in plants is also proposed.
