During lignification, phenyl rings of lignin precursors align to the cellulose molecule surfaces in a controlled and ordered process.
Parasites were identified using the standard keys and, where necessary, they were cleared in lactophenol or stained with polyvinyl acetate and lignin pink.
There is generally a higher expression of genes involved in cellulose and lignin biosynthesis in the wild-type testa as compared to the mutant.
This is largely determined by the age of the late wood that is likely to have high lignin content.
Modified procedure to determine acid insoluble lignin in wood and pulp.
This may relate to covalent binding of lignin to hemicellulose, which confers mechanical strength to the cell wall.
This implies that the construction of leaf biomass is different among lifeform categories (for example lignin versus cellulose versus others).
The combination of phloroglucinol and hydrochloric acid stains the lignin red and increases visibility of annual rings, particularly in the softer wood of young trees.
