Change in ΔtAIabs of horizontally transferred genes relative to the change in ΔtAIabs of genes present at the parent node. Each bar represents an observed variation in tRNA gene content with an overall positive effect on translation. Values are obtained by dividing the expected change in translation efficiency (ΔtAIabs) for genes recently acquired through HGT and genes that were already present in each genome. Relative changes in ΔtAIabs that were significantly larger for horizontally transferred genes are blue, those that were significantly larger for genes that were already present are red, non-significant differences are grey.
