🧵 🌱 RESEARCH 🌱🧵

The influence of pectins and cellulose fibers in the mechanical and adhesive properties of seed mucilage - Gorges et al

🔗 doi.org/10.1093/jxb/...

#PlantScience 🧪

Mucilage spatial architecture before and after pectinase treatment. SEM images of critical point dried seeds. (A, B) Mucilage envelope of chia; arrows indicate cross-linking polysaccharides (CSPs) in between the cellulose fibers in (B) compared with the lack of CSPs in (C). (C) Mucilage of chia after pectinase treatment. Few or no CSPs are visible in between the cellulose fibers. (D, E) Mucilage of collomia; arrows indicate CSPs in (E) compared with the lack of CSPs in (F). (F) Mucilage of collomia after pectinase treatment. Few or no CSPs are visible in between the cellulose fibers. (G, H) Mucilage of flax. Net-like structures are visible on the seed surface (indicated with arrows in H). (I) Seed surface of flax with mucilage-secreting cells (MSCs) after pectinase treatment. No mucilage with the characteristic net-like structure is left to cover the seed surface. Abbreviations: fb, fiber bundle; me, mucilage envelope.
