Taxonomic and functional profiles of straw decomposition bacteria at different decomposition stages. Relative abundances of dominant bacteria at the phylum level (a). Relative abundances of Actinobacteria at the family level (b). Relative abundances of carbohydrate-active enzymes encoding genes (one color per gene) involved in straw decomposition predicted by Actinobacteria (c). For more detailed functional gene profiles of (c), see Additional file 1: Table S1
