Reporter TF analysis. (A) Many stress-related transcription factors were identified as key transcription factors in comparisons of mRNA levels of the amylase-producing strains with those of strain NC (reporter P value < 10⁻⁶). (B) The reporter TF results of comparisons of UV mutation strains with strain AAC. Red indicates that the genes regulated by this transcription factor were upregulated, and blue indicates they were downregulated. Reporter P value < 10⁻⁶. The color key shows significance levels from the reporter TF analysis [−log(reporter P value)]. Red indicates that the genes regulated by the specific TF were upregulated in comparisons of the transcriptomes of two strains, and blue indicates downregulation in transcription of the genes regulated by the TF.
