Using HPLC quantification, we have shown that benzoic acid derivatives stimulate PR-b1 protein synthesis in the leaf discs of Nicotiana tabacum Xanthi nc. The stimulation of PR-b protein synthesis during treatment with several benzoic acid derivatives is described for the first time in the root system of in vitro grown Nicotiana tabacum plantlets. In healthy in vitro grown plantlets the PR-b1 concentration is similar in roots and leaves (200 ng per gram of fresh material). During chemical treatment, however, the PR-b1 concentration increases to a lesser extent in roots than in leaves (10-fold higher in treated roots and 100-fold higher in treated leaves). Benzoic acid derivatives also have a detrimental effect on the growth of in vitro plantlets, which may be related to the accumulation of PR-b proteins.
通过高效液相色谱定量分析，我们发现苯甲酸衍生物能刺激烟草黄花烟草（Nicotiana tabacum Xanthi nc）叶片圆片中PR-b1蛋白的合成。首次描述了几种苯甲酸衍生物处理期间，体外培养的烟草幼苗根系中PR-b蛋白合成受到刺激的情况。在健康的体外培养幼苗中，根和叶中的PR-b1浓度相似（每克鲜重200纳克）。然而，在化学处理期间，根中PR-b1浓度的增加幅度小于叶中（处理后的根中高10倍，处理后的叶中高100倍）。苯甲酸衍生物对体外培养幼苗的生长也有不利影响，这可能与PR-b蛋白的积累有关。
