• Treatment of Cryptomeria and Perilla cell suspension cultures with glyphosate resulted in a marked suppression of the formation of flavans and caffeic acid derivatives, respectively, while it caused only a slight decline in the cell growth. In contrast with 3-deoxy-D-arabino-heptulosonate (DAHP) synthase-Mn isozyme, DAHP synthase-Co isozyme from Cryptomeria and Perilla cells was much more sensitive to inhibition by glyphosate. The addition of 1 to 2 mM glyphosate caused an accumulation of shikimate and quinate and a reduction of L-phenylalanine in both cell cultures. The inhibition of phenylalanine ammonia-lyase (PAL) activity by glyphosate was reversed by exogenously supplied L-phenylalanine to near the control level. Cycloheximide and actinomycin D nullified the recovery by exogenous L-phenylalanine on PAL activity. L-Phenylalanine itself promoted PAL activity to some extent. No recovery of PAL activity in L-a-aminooxy-β-phenylpropionate (L-AOPP)-treated cell cultures could be observed by the addition of L-phenylalanine. Therefore, L-AOPP seems to inhibit the formation of PAL, though it has been considered a competitive inhibitor.
