“Probing molecular architecture and assembly of plant biomaterials with solid-state NMR”
Chemically heterogeneous and structurally amorphous assemblies are essential to
wide-ranging biological tasks that involve water diffusion, mechanical integrity, and protection against pathogenic invasion. Hydrophobic plant composites, formed by lipid-based polyesters and waxes, assemble into the hydrophilic cell walls and work as an efficient barrier to protect the plant organs from dehydration and injuries. Of particular interest is the suberin polyester; we have used a combination of genetic modifications and solid-state NMR techniques to decipher the structural frameworks of 13C-enriched suberin materials obtained from Solanum tuberosum L. (potato). Dynamic nuclear polarization (DNP) strategies are also being developed to enable execution of a broader range of structurally informative experiments on these challenging materials.
Our findings deconstruct the supramolecular organization of this class of biomaterials to shed light on their cooperative dynamics and mechanical performance as well as underscore the design principles of this critical hydrophobic barrier in protective plant tissues. The results offer potential improvements for both sustainable agricultural practice and bio-inspired materials design.
