In addition, degradation of oligo and polysaccharides is more energy effective for producing hexoses for substantial cell-wall remodeling than potential gluconeogenesis (down-regulated during winter hardening) from lipids.
Though grasses are less recalcitrant than woody perennials, slow digestion rates and requirements for substantial quantities of cell wall degrading enzymes add significant process costs and inefficiencies [1].
More striking than the shifts in composition were the substantial changes in cell wall accessibility.
Toxins or substantial amounts of cell wall degrading enzymes are likely not involved in the Pythium-rice interaction, because pathogen invasion was not associated with extensive tissue damage and was not preceded by cell death.
Cell wall associated genes also showed evidence of substantial adaptive selection, suggesting cell wall remodeling has been critical for the survival of MPM.
16 In the region closer to the surface, a substantial degradation and solubilization of cell wall and pectin can be seen due to digestion.
By applying all the three pathways simultaneously, S. cerevisiae could be turned into a 'voracious' yeast, capable of consuming substantial fractions of the plant cell wall in biomass hydrolysates.
In the untreated sample, the secondary cell wall has substantial amounts of lignin; the increase of maleic acid concentration in treatment appears to lead to more lignin reduction in the secondary wall than in the cell corner and compound middle lamella.
This indicates a strong repression of cell wall synthesis, cell wall modification, pectin degradation, cell expansion and cell wall turnover.
If glycan synthesis resided in chloroplasts, the transfer of glycan from chloroplast to cell wall would need substantial energy input.
These results indicate that the loss of texture in digested carrots, as shown in Figure 6b, was mainly caused by substantial dissolution, depolymerization, and destruction of cell wall polymers, particularly the pectic substances.
