Molecular phylogeny of nematode GATA factors. Maximum Likelihood tree of C. briggsae (Cb) and C. elegans (Ce) GATA factors, showing both the PhyML-aLRT Chi2-based parametric statistic (bold) and Neighbor Joining Bootstrap percentiles (regular). Brackets to the right indicate the inferred ancestral clades. Black box brackets indicate genomic linkage found for both nematode orthologs in two clades, while red box brackets indicate linkage found only within one nematode species.
