Fig 6. Conservation of the pairing between tRNAs and hosting or neighboring protein-coding genes among nematodes.

Shown are the fractions of conserved genomic architectures in different nematodes in comparison to C. elegans. Each bar denotes the conservation of localization of a given tRNA type (anticodon) with respect to either the tRNA-hosting gene or the adjacent protein-coding genes. Shown are the fractions of conservation of a given anticodon within the transcripts of a specific hosting protein-coding gene (red bars), and the conservation of the adjacent upstream (yellow bars) or downstream (blue bars) protein-coding genes in the vicinity of a given tRNA type (anticodon). The yellow and blue bars were generated based on all the individual tRNA genes that were not localized within the transcripts of protein-coding genes.
