Normal carrot cell suspension treated with BSM showed changes in the free amino acid levels. Most of the amino acids either increased or remained constant, but the levels of valine and leucine decreased markedly. The level of isoleucine was significantly unchanged. In BSM-tolerant cells the free amino acid levels were not decreased. Exogenously supplying these three amino acids to normal cells provided the most effective recovery of growth inhibition. Normal cells treated with GLY showed changes in the free amino acid levels. Most of the amino acids either increased or remained constant. The tolerant cells had higher levels of phenylalanine and tyrosine than that of normal cells. The combination of phenylalanine, tyrosine and tryptophan showed the best recovery of GLY-induced growth inhibition. In GLU-tolerant cell suspensions, the GLU-treated normal cells had a high level of accumulated ammonia whereas the tolerant cells did not. GLU-induced growth inhibition was recovered by glutamine incorporation. Exposure to GLU had no effect on ammonia accumulation in tolerant cells, suggesting that these cells may have an effective mechanism to avoid a high intracellular ammonia level. Based on these findings, the high level of valise, Lucien and isoleucine in BSM-tolerant cells; phenylalanine, tyrosine in GLY-tolerant cells; and glutamine in GLU-tolerant cells may be the result of adequate synthesis supported by overproduction of the target enzyme and/or production of a target enzyme insensitive to the herbicide which is involved in the tolerance mechanism.
