Phenolic Acids in Wheat Coleoptile Cell Walls

Phenolic acids in wheat coleoptile cell walls.

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 es...

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...
