THE phenolic acids, ferulic and p-coumaric, are bound to cell walls of plants of the Gramineae (which include grasses and cereals) and it was thought that these acids were esterified to lignin and so occurred only in lignified cell walls1–4. But it has been shown recently that in cell walls of Lolium multifiorum Lam., which contain ferulic acid and a small amount of p-coumaric acid mainly as their trans isomers, the acids are esterified at their carboxyl groups to polysaccharides5–7.

TLDR
Primary cell walls from exponentially growing cell-suspension cultures of spinach contained ferulic acid and p-coumaric acid esterified with galactopyranose and arabinopyrAnose residues of polysaccharides, suggesting that acidic and neutral pectins carry ferulic Acid on the non-reducing termini of the neutral arabinose- and/or galactose-containing domains.

The distribution of ester-linked ferulic acid in the cell walls of angiosperms
Ester-linked ferulic acid occurs in the cell walls of two major groups of angiosperms, the commelinid monocotyledons and the ‘core’ Caryophyllales, at concentrations >3.5 mg g−1 cell walls, and hasExpand
Distribution of Autofluorescence and Esterase and Peroxidase Activities in the Epidermis of Wheat Roots
TLDR
In the wheat root, peroxidases and esterases specific for a-naphthyl esters of acetate, propionate and butyrate are concentrated in cell walls, particularly the outer wall of epidermal cells undergoing extension, and ferulic acid and diferulate were shown to be constituents of wheat-root cell walls.

Expression of a fungal ferulic acid esterase increases cell wall digestibility of tall fescue (Festuca arundinacea).
TLDR
It is concluded that targeted FAEA expression is an effective strategy for improving wall digestibility in Festuca and, potentially, other grass species used for fodder or cellulosic ethanol production. Expand
Ferulic acid is bound to the primary cell walls of all gymnosperm families.
TLDR
The present results postulate that the extant classes of gymnosperms are monophyletic and no class is sister to the angiosperms. Expand
Phonolic components of the primary cell wall and their possible rôle in the hormonal regulation of growth

TLDR
Gibberellic acid (GA3, 10-11–10-6 M) promoted the expansion of cultured spinach cells and simultaneoulsy suppressed peroxidase secretion, reduced the activity of cellular phenylanine ammonia-lyase and favoured the accumulation of wall-esterified ferulate and of extracellular soluble phenolic aglycones.

Polysaccharides and associated components of mesophyll cell-walls prepared from grasses
Abstract Mesophyll cells have been prepared from rye-grass leaves by a procedure similar to that used by Edwards and Black 1 for crab-grass. Successive filtrations through nylon cloth of 300-, 80-,Expand
Feruloylation in Grasses: Current and Future Perspectives
TLDR
It is argued that, until recently, the specific role of feruloylation in these various processes has been established largely by indirect experiments and, although these studies reached similar conclusions about the potential importance of wall feruloyslation, they suffer from a common problem: namely they depend on correlations between two processes and do not stem from a detailed understanding of the mechanisms of ferULoylation.

Diferulic and ferulic acid in the cell wall of Avena coleoptiles : their relationships to mechanical properties of the cell wall
Alkaline hydrolysis liberated ferulic and diferulic acid from polysaccharides of the Avena coleoptile (Avena sativa L. cv. Victory I) cell walls. The amount of the two phenolic acids bound to cellExpand
Targeting 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).
TLDR
It is concluded that targeting FAEA expression to the Golgi or apoplast is likely to be an effective strategy for improving wall digestibility in grass species used for fodder or cellulosic ethanol production. Expand

Differences in MW of the H 2 O-soluble phenolic compounds obtained by treatment of grass cell-walls with C 1 and C x components suggest that these enzymes could have different modes of action. Expand
