Glucan degradation locus in C. bescii, C. kronotskyensis, and C. saccharolyticus. Numbers indicate CAZy family; squares, glycoside hydrolases; ovals, carbohydrate binding modules; rounded squares, polysaccharide lyases. Genes are aligned by homologous families. Locus tags are written above, and boxes underneath represent transcription level on cellulose (left) and switchgrass (right). Red and blue represent high and low levels of transcription, respectively.
