WebChromoviruses, chromodomain-containing retrotransposons, are the only Metaviridae (Ty3/ gypsy group of retrotransposons) clade with a Eukaryota-wide distribution. They have a common evolutionary origin and are the most prolific and diverse Metaviridae clade. The fusion of a retrotransposon and a chromodomain, was most probably responsible for … WebNational Center for Biotechnology Information

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. WebOne of them, the chromoviruses, has a wider host range, being found in plants, fungi and vertebrates. Chromoviruses got their name because their pol gene encodes an integrase with a chromodomain (‘chromatin organization modifier domain’), a nucleosome-binding integrase portion which can mediate sequence specific integration ([10,13-15]. chip truwit md
