Analysis of genes putatively acquired by HGT. a Using an AI >30 or >0, between 45 % and 36 % of putative HGT genes are present in orthologous gene cluster categories unique to the Globodera and may give an insight into the relatively recent HGT history since the Globodera–Meloidogyne divergence. b Genes putatively acquired by HGT (AI >0) are significantly closer to transposable elements when compared to all other genes not predicted to be acquired by HGT (p <0.000, Mann–Whitney U test). c There was no significant association of any independent class of transposable element with genes putatively acquired by HGT. Despite the divergent transposable element composition of Globodera (Additional file 11: Figure S6), these were not associated with putative HGT events specific to Globodera
