Figure 1

A) Synthetic crystalline cellulose (Avicel) displayed a diffractogram pattern consistent with diffractogram from plant biomass derived from Arabidopsis whole plant biomass (B) Schematic of the sample scan used to estimate the experimental accuracy of pressed biomass at 22.5° 2-theta. Experimental accuracy was determined to be 8.99% (C) Roots, leaves and shoots from Arabidopsis plants were sub-sampled and analyzed by XRD showing variability of RCI between tissues. (D) RCI values for ball milled samples, whole plant sample and stem, rosette (leaf) and root values. *Rosette RCI was significantly lower than stems or roots (P<0.001 ANOVA) whereas stems and roots were not significantly different. (E) RCI values for ball milled samples, whole plant sample and stem, rosette (leaf) and root values with experimental accuracy included.
