Sulfur regulome-associated transcription factorsa

TABLE 1 
  • a The 14 transcription factors identified as being part of the sulfur regulome are listed together with the transcription factor family to which they belong. For each transcription factor gene (PFLU identifier number [ID] and gene family), a profile of differential expression across sulfur nutrients is shown, with significant differential expression (two-tailed t test [compared to “no-sulfur” growth conditions]) marked as “D” (decreased expression), “I” (increased expression), or “N” (no change in expression) (see Materials and Methods). “# Co-regulated” indicates the number of genes identified as potentially regulated by transcription factor. Data in the “Shannon Entropy” column were calculated as the amount of information, defined as the number of possible sulfur nutrients, that is provided by a significant change in transcription factor expression. Transcription factors in bold were selected for deletion.
