Fig. 7

Discriminant features between high and low yielders of glucose (GlcE) or xylose (XylE), upon enzymatic saccharification of mature miscanthus biomass, detected by t tests (α = 0.05). High yielders, refer to the top 50% glucose or xylose saccharification efficiency values, whereas low yielders are the bottom 50%. Arrows represent significantly different features, i.e. when P ≤ 0.05 (− log₁₀ 0.05 ≈ 1.30). Upward pointing arrows represent features positively correlated with the saccharification efficiency, whereas downward pointing ones are negatively correlated with saccharification efficiency. The colour of the arrows indicates the Pearson correlation coefficient (as in Fig. 5). Box and whisker plots of the distribution of biomass compositional measurements are shown in Additional file 7. Ara/Xyl, arabinose-to-xylose ratio; N is a normalised value representing the total epitope abundance for each monoclonal antibody (mAb; more details in Additional file 1)
