Duplication and gene loss at the ddx-27 locus. a Gene tree of ddx-27. ddx-27 is conserved across all analyzed nematode genomes. b Gene tree of Y71G1G12B.25 and Y71G1G12B.26. c Genomic configuration of host gene and ASTs in 20 nematode genomes. With exception of T. spiralis, it has up to two ASTs that have most likely arisen through a duplication event in the ancestor of clade IV and V nematodes. Subsequently, one of the copies was lost independently in various lineages. The ddx-27 locus in M. incognita was split between Minc_Contig329 and Minc_Contig2119. The genes Y71G1G12B.25 and Y71G1G12B.26 could be identified in both Meloidogyne species but had large gaps and were therefore not included in the phylogenetic analysis
