Fig. 1: Chromosome-level reference genomes for Heligmosomoides bakeri and Heligmosomoides polygyrus.
From: Ancient diversity in host-parasite interaction genes in a model parasitic nematode
a The position of H. bakeri and H. polygyrus within Strongylida. Phylogeny was inferred using the amino acid sequences of 511 BUSCO genes that were present and single copy in at least 18 of the 20 species. H. bakeri and H. polygyrus are highlighted in bold. Suborders are indicated. Scale in substitutions per site is shown. Inset: a H. polygyrus female. b Cumulative length plots showing contiguity of all single nematode assemblies and both existing H. bakeri reference genomes (PRJEB1203 and PRJEB15396). The dotted line indicates that the curve for the H. bakeri PRJEB1203 assembly extends beyond 10,000 contigs (the total number of contigs in the assembly is 20,569). c Hi-C contact map for the nxHelBake1.1 reference genome. Chromosome names are indicated. The Hi-C contact map for the ngHelPoly1.1 reference genome is shown in Supplementary Fig. 3A. d Distribution of BUSCO genes in the six H. bakeri chromosomes in the nxHelBake1.1 reference genomes coloured by their allocation to the seven ancestral Nigon elements defined by Gonzalez de la Rosa et al. 42.
