Occurrence of MLX utilization loci in marine Bacteroidetes. (A) Schematics of MLX utilization loci in marine Bacteroidetes. (B) Co-occurrence analysis of genes in MLX utilization loci of 11 marine Bacteroidetes. The dendrograms shown above and on the right of the heatmap depict the pairwise similarities between rows and columns, respectively. Red solid triangles indicate selected strains for growth studies. (C) Growth of selected marine Bacteroidetes strains on xylans. Cultures without carbon sources were used as controls. ^**P < 0.01, ^*P < 0.05 (two-tailed t-test). ΔOD₆₀₀ values are from triplicate experiments (mean ± SD).
