Variations in the ARTP mutants tolerant to acetic acid. a Venn gram of SNVs in A7, AQ8-1, and AC8-9. b “Hot spots” of mutagenesis loci in the ARTP mutants. Gene names are shown above the lines, arrows indicate transcriptional directions. Variations are highlighted in nucleotide rows which from top to bottom represent ZM4, A7, AQ8-1, and AC8-9, respectively
