Gene expansion of CAZYs in the Botryosphaeria lineage. A. Overall comparison of glycoside hydrolases (GHs), glycosyl transferases (GTs), polysaccharide lyases (PLs), carbohydrate esterases (CEs), auxiliary activities (AAs), and carbohydrate-binding modules (CBMs) against other lifestyles fungi. B. CAZYs expanded in the Botryosphaeria lineage mainly involved in hemicellulose and lignin degradation. Over-represented (+2 to 0) and under-represented (0 to −2) numbers are depicted as Z-scores for each line in heatmap.
