The more active members of a proposed class of auxin transport inhibitors have been shown to have the ability to inhibit the active movement of auxin at concentrations where they have little effect on auxin action and no significant auxin activity. They have also been shown to give rise to characteristic biphasic dose-response curves on cress root growth. Based on these physiological similarities and other common physiological properties, it is concluded that they may achieve their effects by a common mode of action which differs from that of other known auxin transport inhibitors. It is suggested that the name "phytotropins" be given to the class of auxin transport inhibitors now defined by a similar mode of action and common chemical properties.
拟议的一类生长素运输抑制剂中活性较高的成员已被证明具有在对生长素作用影响较小且无明显生长素活性的浓度下抑制生长素主动运输的能力。它们还被证明在拟南芥根生长上产生特征性的双相剂量反应曲线。基于这些生理相似性和其他共同的生理特性,可以得出结论,它们可能通过不同于其他已知生长素运输抑制剂的共同作用模式来实现其效果。建议将“植物生长调节剂”这一名称赋予现有的生长素运输抑制剂类别,这些抑制剂现在通过类似的作用模式和共同的化学特性来定义。
