Additional file 2: Figure S1. of Complete mitochondrial genomes of four entomopathogenic nematode species of the genus Steinernema Taisei Kikuchi Tanzila Afrin Mutsuhiro Yoshida 10.6084/m9.figshare.c.3613712_D1.v1 https://springernature.figshare.com/articles/journal_contribution/Additional_file_2_Figure_S1_of_Complete_mitochondrial_genomes_of_four_entomopathogenic_nematode_species_of_the_genus_Steinernema/4371086 Principal component analysis of the codon usage in Steinernema mitochondrial genes. The first (PC1) and the second principal component (PC2) account for 98.1 % of the variability. Abbreviations: S.car, S. carpocapsae; Sgla, S. glaseri; Skus, S. kushidai; Slit, S. litorale; Bxyl, B. xylophilus; Pred, P. redivivus; Ptri, P. trichosuri. Figure S2. Phylogenetic relationships among Steinernema species inferred from nearly full-length nuclear 18S rRNA genes. A maximum-likelihood tree based on nucleotide sequences, with Panagrellus redivivus as the outgroup, was generated with the substitution model TVM+ G. Bootstrap values are given on the branches. The scale-bar represents the number of nucleotide substitutions per site. (PDF 28 kb) 2016-08-05 05:00:00 Mitochondria Genome Insect parasitic nematode
