Detecting Horizontal Gene Transfer between Closely Related Taxa
Fig 9
Genes with significant probability to be the product of HGT.
For each significant gene, there are three bars corresponding to each pair of strains. The height of the bar represents the number of times (i.e. number of witness genes in reference species) that the gene was found with significant support (in log scale) to be derived from HGT. The value -1 indicates that this gene is not an SI-based HGT candidate between these two strains (including cases where the gene is simply not present in both strains). Zero means we did not find any significant witness for that gene.
