Values are mean ± standard deviation of biological and technical replicates (minimum for each value, n = 4; total samples for each monosaccharide, n = 60).

Leaf and stem samples used for this assay were collected at the end of the experiment from the three miscanthus genotypes grown at 75 % SWC.

Supplementary Data Table S6 shows the ANOVA results for the matrix monosaccharides.
