Putative orthologous gene clusters in related nematode species and transcriptomic analysis. a The predicted protein sets of five plant parasites, from two independent origins of parasitism, were compared to that of the free living nematode C. elegans. The analysis includes two cyst nematodes, G. rostochiensis and G. pallida, two root knot nematodes, M. hapla and M. incognita, the pine wilt nematode B. xylophilus and the free living nematode C. elegans. The histogram shows the number of clusters shared uniquely between the species highlighted below. A total of 1986 clusters of genes are present in both cyst nematode species and absent from all other nematodes tested (orange). b Focusing on four orthologous gene cluster categories (all nematodes, all plant parasites, a single origin of plant parasitism and a single origin of sedentary biotrophy), the percentage of genes present in differential super-clusters suggest that those genes unique to the Globodera are preferentially differentially regulated throughout the adapted life cycle. c Analysing the relative abundance of genes from each orthologous gene cluster category in each of the differential expression super-clusters suggests that those genes specifically differentially regulated during the infective juvenile stage are those unique to the Globodera
