Abstract
Cell suspension cultures of Chenopodium rubrum accumulate high amounts of metabolically active glucose esters of p-coumaric and ferulic acid. Pulse-labelling experiments using [14C]phenylalanine and application of the phenylalanine ammonia-lyase (PAL) inhibitor L-α-aminooxy-β-pnenylpropionic acid (AOPP) revealed that the glucose esters are subject to high turnover. A considerable portion of the ferulic acid was found as an insoluble component, probably bound to cell wall material. Application of m-fluoro-DL-tyrosine (MFT), an effective inhibitor of tyrosine biosynthesis via L-arogenate, markedly increased the amount of 1-p-coumaroyl-and 1-feruloyl-glucose accumulated.Keywords
