Reducing cell wall feruloylation by expression of a fungal ferulic acid esterase in Festuca arundinacea modifies plant growth, leaf morphology and the turnover of cell wall arabinoxylans
A feature of cell wall arabinoxylan in grasses is the presence of ferulic acid which upon oxidative coupling by the action of peroxidases forms diferuloyl bridges between formerly separated arabinoxylans. Ferulate cross-linking is suspected of playing various roles in different plant processes. Here we investigate the role of cell wall feruloyaltion in two major processes, that of leaf growth a...
متن کاملExpression of a fungal ferulic acid esterase in alfalfa modifies cell wall digestibility
BACKGROUND Alfalfa (Medicago sativa) is an important forage crop in North America owing to its high biomass production, perennial nature and ability to fix nitrogen. Feruloyl esterase (EC 3.1.1.73) hydrolyzes ester linkages in plant cell walls and has the potential to further improve alfalfa as biomass for biofuel production. RESULTS In this study, faeB [GenBank:AJ309807] was synthesized at G...
متن کاملTargeting expression of a fungal ferulic acid esterase to the apoplast, endoplasmic reticulum or golgi can disrupt feruloylation of the growing cell wall and increase the biodegradability of tall fescue (Festuca arundinacea).
In the cell walls of grasses, ferulic acid is esterified to arabinoxylans and undergoes oxidative reactions to form ferulates dimers, trimers and oligomers. Feruloylation of arabinoxylan is considered important not only because it leads to cross-linked xylans but also because ferulates may act as a nucleating site for the formation of lignin and hence link arabinoxylans to lignin by forming a l...
متن کاملEffect of humic acid and mulches on characteristics of tall fescue (Festuca arundinacea Schreb.)
Application[Editor 321] of biotic growth regulators (e.g. humic components) and appropriate mulches is recommended to improve turfgrass quality especially in arid andsemi-arid climate zones. However, limited number of studies have investigated their effect on lawn establishment. To investigate the effect of humic acid (HA) and selected mulches on characteristics of Festuca arundinacea in its p...
متن کاملEffect of humic acid and mulches on some characteristics of tall fescue (Festuca arundinacea Schreb.)
Application of biotic growth regulators (e.g. humic components) and appropriate mulches is recommended to improve turfgrass quality. However, limited research has investigated their effect on lawn establishment. To investigate the effect of humic acid and selected mulches on characteristics of Festuca arundinacea in its planting stage, a factorial experiment based on a completely rando...
