Cellulosic Fibers: Role of Matrix Polysaccharides in

Mesoporosity was suggested as a new parameter for G-layer characterization [14]. Gelatinous cell-wall layer is deposited inward to the xylan type secondary wall layers; the degree of S-layer development in fibers with G-layer differs from well pronounced, like in tension wood [15], to barely detectable, as in flax [2].

Prior secondary cell wall formation is required for gelatinous layer

In hardwood trees, tension wood is formed along the upper side of a bending stem and contains wood fiber cells that have a gelatinous layer (G-layer) inside the SCW. In a previous study, we generated nst/snd quadruple-knockout aspens ( Populus tremula × Populus tremuloides ), in which SCW formation was impaired in 99% of the wood fiber cells.

Mucilaginous Fiber: The Good, the Bad, and the Gooey

Chia seeds, flaxseeds, and agar agar all contain a type of vicious, soluble fiber called mucilage that swells up and becomes gelatinous and gooey when it makes contact with water. Many Paleo recipes call for high-mucilage foods to create certain jelly-like textures (think chia seed pudding, for example!). And, the unique properties of this ...

Ethylene signaling induces gelatinous layers with typical features …

We demonstrate that ACC and ethylene induce gelatinous layers (G-layers) and alter the fiber cell wall cellulose microfibril angle. G-layers are tertiary wall layers rich in cellulose, typically found in tension wood of aspen trees. A vast majority of transcripts affected by ACC are downstream of ethylene perception and include a large number ...
