Genome completeness (A) and single-copy gene abundance (B) of Burkholderiaceae bacteria. The genome completeness was estimated by the conservation rate of 568 single-copy genes in the complete genomes of Mycoavidus sp. B2-EB, Mycoavidus cysteinexigens B1-EBT and AG77, Mycetohabitans rhizoxinica HKI 454T, Paraburkholderia phytofirmans PsJNT, Burkholderia cepacia ATCC 25416T, Caballeronia insecticola RPE64T, Lautropia mirabilis NTCT12852T, Pandoraea apista DSM 16535T, Ralstonia pickettii 12JT, Cupriavidus necator N1T, Polynucleobacter asymbioticus QLWP1DMWA1T, and Polynucleobacter necessarius STIR1T, as well as in the incomplete genomes of “Ca. Glomeribacter gigasporarum” BEG34, BEG1, JA201A, and IN211 and Mycetohabitans endofungorum HKI 456T. *, Pb, Paraburkholderia. **, Cb, Caballeronia.
