Fig 2. Horizontal gene transfer in H. dujardini.

(A) Horizontal gene transfer ratios in various metazoa. For a set of assembled arthropod and nematode genomes, genes were repredicted ab initio with Augustus. Putative horizontal gene transfer (HGT) loci were identified using the HGT index for the longest transcript for each gene from the new and the ENSEMBL reference gene sets. In most species, the ab initio gene sets had elevated numbers of potential HGT loci compared to their ENSEMBL representations.

Classification of the initial HGT candidates identified in H. dujardini by their phylogenetic annotation (prokaryotic, nonmetazoan eukaryotic, viral, complex HGT, and likely non-HGT metazoan and complex), their support in RNA-Seq expression data, and the presence of a homologue in R. varieornatus.
