During cell wall deposition and lignification
, xylans are cross-linked by peroxidase-mediated coupling of ferulate monomers into a complex array of dimers and trimers and by extensive copolymerization of these ferulates into lignin (see review by Grabber et al., 2004).
A number of studies indicated that PPO is involved in the oxidation of polyphenols into quinines (antimicrobial compounds) and the lignification
of plant cell walls during microbial invasion.
There was a strong positive correlation between lignin content and cooking time ([r.sup.2] = 0.72).This suggests that HTC defect entails lignification
Vigorous growth was observed with higher lignification
and a strong
The difference in degradation values was probably due to lignification
and maturity which interferes the degradation of structural carbohydrates by acting as a physical barrier to rumen microbial enzymes (Moore and Jung, 2001).
Peroxidase (PO) play role in lignification
and subrization of cell wall during plant pathogen interactions (Low and Merida 1996; Wojtaszek 1997).
Accumulation of lignin in relation to change in activities of lignification
enzymes in loquat fruit flesh after harvest.
Forage quality generally declines with maturity as nutrients are translocated from aging tissue to areas of meristematic activity, overall cell wall mass increases, and sites of lignification
increase in certain plant parts (Akin et al., 1983).
"I can't say that we ever get total seed maturity, because we don't," she says, nor is there much stem lignification
. "The goal isn't to make a high-alcohol bomb," she adds.
The goal of the symposium was to highlight recent advances in understanding the impact of lignification
Enzyme cytochemistry reveals biochemical activities probably related to lipid utilization routes for the lignification
processes and for synthesis of extractives; these results suggest that the formation and maturation of woody tissue is very active at the beginning of the rainy season.
In this way, phenolpropanoid skeletons serve as substrates to begin the lignification
process, which has recently been proposed as a mechanism of resistance to injuries provoked by fungal pathogens (Tiburzy & Reisener, 1990).
