Assignment of genes to COG categories. Chart depicting the percentage of genes assigned to various COG categories for both regular genes and genes identified as LGT events into the (a) Halobacteria and (b) Thermoprotei. The COG categories shown demonstrated a statistically significant disparity between LGT genes and non-LGT genes beyond a 95% confidence interval. The categories depicted with an * fell just below the 95% threshold.
