Figures & data
Figure 1. Maximum likelihood tree of 13 PCGs in amphipod mitochondrial genomes with their accession numbers. Species in orange represent the Grandidierella genus. Non-parametric bootstrap values (based on 200 times resampling) are shown at nodes. The phylogenetic tree was inferred using IQ-TREE v1.6.12 with the ‘–spp’ option to allow partition-specific evolution rates. The best-fit model for each PCG was determined by ModelFinder (Kalyaanamoorthy et al. Citation2017) implemented in IQ-TREE, based on Akaike information criteria. The phylogenetic tree was visualized by FigTree v1.4.4. Isopod species (Ligia oceanica) was used as an outgroup.
