Fig. 5From: Discovery and characterization of the evolution, variation and functions of diversity-generating retroelements using thousands of genomes and metagenomesDGR examples. TRs, VRs, RTs and target genes (ORFs) are filled with different colors, while the arrow direction represents the direction of these elements. (a) DGR found in NZ_FNTS01000002.1 contains 21 VRs within ORF17814, thus introducing huge variation to this target gene; (b) DGR from NZ_DS999412.1 contains six VRs, involving different target genes; (c) NZ_GL988634.1 has a typical DGR structure similar with BPP-1, and the target gene (ORF41) serves as phage tail domain protein; (d) An untypical DGR from NC_019683.1. It contains three VRs that are all located in C-terminal of target genesBack to article page
