WebRetroviruses are present in genomes of early eukaryotes but significantly expanded in vertebrates. Gypsy-like retroviruses (aka chromoviruses, defined via RT and gag similarity) are often found conserved as full-length elements including env genes in most lower eukaryote genomes (e.g., Caenorhabditis elegans), but WebInterestingly, all plant metaviruses devoid of additional coding domains seem to be chromoviruses. It is therefore likely that the classification of Metaviridae will be reconsidered in future, to separate the two groups of metaviruses and recognize the existence of the chromodomain.
