Supplementary information for NEMBASE4: the nematode transcriptome resource Benjamin Elsworth, James Wasmuth and Mark Blaxter Supplementary File S1: Picornavirales RDRP alignment Supplementary File S2: nanos zinc finger domains alignment Supplementary File S3: HemH/ferrochelatase protein alignment Supplementary Table S1: The NEMBASE4 species list Supplementary Table S2: Candidate laterally transferred gene tribes in the Tylenchina Supplementary Figure S1: The strongylid nanos-like zinc finger domains This unrooted Bayesian phylogeny shows that the three nanos zinc finger domains identified in the animal parasites Ancylostoma caninum and Dictyocaulus viviparus do not cluster with nanos zinc finger-like sequences from Caenorhabditis elegans. The branches are coloured corresponding to the Bayesian posterior probability, with pp of 0.98
