Fig. 2From: Discovery and characterization of the evolution, variation and functions of diversity-generating retroelements using thousands of genomes and metagenomesDistribution of DGRs in different body sites. (a) Absolute numbers of DGRs in the 10 body sites, by which the legend is sorted. (b) The normalized frequencies of DGRs in these body sites: DGR_number_per_100Mbp_contigs = number of DGRs found in this body site * 100 / assembly size (Mbp)Back to article page
