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]. WebThe chromoviruses are Ty3/gypsy retrotransposons that have chromodomains located in their integrase C termini. Three groups of chromoviruses are described based on amino acid sequence relationships of their chromodomains and comparisons of their chromodomains to the heterochromain protein I (HP1) chromodomain, which typically … downtowntc t2hostedWebRetroviruses are present in genomes of early eukaryotes but significantly expanded in vertebrates.
