Transcriptional response of Che-type chemotaxis systems and flagellar genes in Caldicellulosiruptor species. Gene type is indicated on the inner ring: core Che component (light blue), additional Che component (gray), enzyme (orange) or flagella (pink). Tracks from outer to inner: for transcription level (LSM), C. bescii, cellulose (A); C. bescii, switchgrass (S); C. kronotskyensis, cellulose; C. kronotskyensis, switchgrass; C. saccharolyticus, cellulose; C. saccharolyticus, switchgrass; for differential transcription (Diff), C. bescii (Be), C. kronotskyensis (Kr), and C. saccharolyticus (Sa). Locus tags and transcription values can be seen in Table S3 and S4 in the supplemental material.
