WebJan 22, 2004 · Chromoviruses in the key Amniota lineage, the reptiles, have been analyzed by PCR to explain their evolutionary dynamics in amniotes. Phylogenetic analyses provide evidence for a novel centromere-specific chromoviral clade that is widespread and highly conserved in all seed plants. WebThe chromoviruses are Ty3/gypsy retrotransposons with chromodomains at their integrase C termini. Chromodomains are logical determinants for targeting to heterochromatin, …

WebMar 5, 2010 · In flowering plants, chromoviruses are phylogenetically distinct from the lineage containing MAGGY and they are classified into four clades, Reina, Tekay, Galadriel and CRM [16], [19]. Members of CRM were originally known as Gypsy elements which accumulate in centromeric and pericentromeric regions in plant genomes [20] – [23]. WebOct 15, 2001 · In most chromoviruses including Pyret the zinc finger motif is present once in the NC domain. The retroviral zinc finger motif is flanked by basic amino acids that have been shown to be important for both RNA packaging and viral infectivity (34, 35). Generally, the zinc finger motifs of chromoviruses are also flanked by basic residues, even ...

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]. rbh management chathamWebCaulimoviruses Plant caulimoviruses ( Caulimoviridae) are double-stranded DNA unenveloped pararetroviruses that do not regularly integrate into the host genome for replication.
