Fig. 5: Sorghum secondary cell walls have a lower ratio of crystalline to amorphous cellulose than Arabidopsis.
From: A grass-specific cellulose–xylan interaction dominates in sorghum secondary cell walls

An overlaid CP-PDSD experiment with short-mixing time (30 ms) on sorghum and Arabidopsis stem tissue shows intramolecular interaction cross peaks of cellulose in different environments in four regions. a Interactions between C1 and C6 of cellulose. b Interactions between C2 and C4, and C3 and C4 of cellulose. c Interactions between C1 and C4 of cellulose. d Interactions between C4 and C6 of cellulose. Sorghum shows significantly higher intensity of immobile three-fold screw xylan cross peaks in panel (a), but much less intensity of two-fold screw xylan cross peaks in panel (d) than Arabidopsis. All four regions demonstrated fewer crystalline cellulose intramolecular cross peaks were detected in sorghum than in Arabidopsis.
