Phenolic acids in wheat coleoptile cell walls.

چکیده

The phenolic constituent of nonvascular cell walls of wheat (Triticum aestivum L.) coleoptiles, which yields vanillin upon nitrobenzene oxidation, is not lignin as I previously claimed. It seems to be mainly ferulic acid bonded to carbohydrate, probably by an ester linkage. The acid is associated with a fraction of the wall rich in arabinose and xylose, although it is not known whether it is esterified directly with these pentose residues. The phenolic-carbohydrate complex is released by cellulase, but not by pronase or a mixture of hemicellulases.

Lignin formation in wheat coleoptile cell walls: a possible limitation of cell growth.

Four growth-influencing compounds-hydroxyproline, 2,2'-dipyridyl, 2-chloroethylphosphonic acid, and indoleacetic acid-were used to examine the relationship between lignin formation and growth of wheat coleoptile sections. Hydroxyproline and 2-chloroethylphosphonic acid, at low concentrations, inhibited growth and increased lignin content. Dipyridyl, which promoted coleoptile elongation, decreas...

Immunocytochemical localization of a wheat germ lysozyme in wheat embryo and coleoptile cells and cytochemical study of its interaction with the cell wall.

Among several wheat (Triticum aestivum L.) germ proteins able to lyse Micrococcus lysodeikticus, one lysozyme (W1A) was purified by ion-exchange chromatography, gel filtration, and preparative polyacrylamide gel electrophoresis. Polyclonal antibodies against this lysozyme were raised in rabbits. The in situ localization of W1A lysozyme was achieved by the indirect protein A-gold technique. Larg...

Changes in the alkaline-labile phenolic compounds of wheat straw cell walls as affected by SO2 treatment and passage through the gastro-intestine of sheep

Sheep were fed two rations based on untreated (WS) and SO2-treated (SO2-WS) wheat straw, and the effect of chemical treatment and passage through the gastro-intestine on the composition and degradation of ester and ether-linked cell wall (CW) phenolics was studied. The SO2 treatment reduced the content of total ferulic acid (FA) and p-coumaric acid (PCA) by 35% while tripling the level of vanil...

Investigation of the effect of light, phenylalanine and caffeic acid on the production of phenolic acids in cell suspension culture of Salvia leriifolia

Abstract: Salvia leriifolia is a medicinal plant belonging to lamiaceae family. In this study, the influence of light, phenylalanine and caffeic acid on cell growth and accumulations of phenolic acids were investigated. For this propose, the leaf explants were cultured in MS medium supplemented with BAP and NAA for callus induction. A cell suspension culture of S. leriifolia derived from lea...

Wheat Bran Phenolic Acids: Bioavailability and Stability in Whole Wheat-Based Foods.

Wheat bran is generally considered a byproduct of the flour milling industry, but it is a great source of fibers, minerals, and antioxidants that are important for human health. Phenolic acids are a specific class of wheat bran components that may act as antioxidants to prevent heart disease and to lower the incidence of colon cancer. Moreover, phenolic acids have anti-inflammatory properties t...
