  1. GWAS results by treeWAS showing single nucleotide polymorphisms (coordinate relative to MTB H37Rv in SNP column) associated with classification of MTBC isolates as M. tuberculosis variant bovis (MBO). For SNPs within genes or ORFs, the classification and putative function is listed, as well as select information about essentiality by transposon mutagenesis studies from Mycobrowser [https://mycobrowser.epfl.ch/]. Likely false positive calls of association for SNPs with only 1–2 occurrences are highlighted by bolded rows
