All antibiotic-resistant mutant strains were named based on the number of passes (P) in a specific antibiotic (K: Ksg, S: Strep, C: Cip, SC: Strep-Cip). All antibiotic-resistant mutants were selected from two separate evolutionary lineages, and named L1 for lineage 1 or L2 for linage 2.
∗Parent: High growth rate mutant parent to all of the strains in the table.
+Mutated genes are likely to be functional, although the mutated genes' functionality has not been tested in this study.
Mutation in the non-coding DNA sequences located between genes.
Genomic position numberings correspond to Mycoplasma mycoides JCVI-Syn3B and P026 (CP053944).
Synonymous mutation: mutation does not change in the encoded amino acid sequence.
