WebOct 8, 2008 · We discuss but one example, the most interesting instance of using this indicator – the chromodomain-containing Ty3/Gypsy LTR retrotransposons called chromoviruses . Chromoviruses are the most ancient branch of Ty3/Gypsy LTR retroelements as they have been described in the genomes of plants, fungi and … 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].
WebIn Ty3-gypsy LTR retrotransposons, tandem repeats were detected both in non-chromoviruses and chromoviruses, yet to a different extent. Non-chromovirus Tat and chromoviruses harbored tandem repeats both within the LTRs and UTRs, whereas non-chromovirus Athila had tandem repeats only embedded within the UTR adjacent to the … WebJames Shapiro is a bacterial geneticist who studies mobile genetic elements and bacteria as multicellular organisms. He is interested in evolution by natural genetic engineering.
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. WebMar 1, 2013 · Results. We conducted a comprehensive survey of chromoviruses within the Beta vulgaris (sugar beet) genome, and found a highly diverse chromovirus population, with significant differences in element size, primarily caused by their flanking LTRs. In total, we identified and annotated full-length members of 16 families belonging to the four plant …
