Genomic Heterogeneity in a Natural Archaeal Population Suggests a Model of tRNA Gene Disruption
A model for the intron gain and fragmentation processes of tRNA genes among the heterogeneous C. subterraneum genomes through site-specific recombination of a mobile element and homologous recombination. Dotted lines indicate the genomes of putative heterogeneous C. subterraneum strains. The tRNAThr gene, a fragment of it, and its intron are denoted by a red arrow, red rectangle, and yellow line, respectively (not to scale). The colors correspond to those in Figure 2. Whereas int represents the integrase gene, attP and attB denote the attachment sites for integration.
