It has not been easy to make sense of the pleiotropic effects of plant hormones, especially of auxins; but now, it has become possible to study these effects within the framework of what we know about signal transduction in general. Changes in local auxin concentrations, perhaps even actively maintained auxin gradients, signal to networks of transcription factors, which in turn signal to downstream effectors. Transcription factors can also signal back to hormone biosynthetic pathways.
理解植物激素尤其是生长素的多效性作用并非易事；但现在，在我们对一般信号转导的了解框架内研究这些作用已成为可能。局部生长素浓度的变化，甚至可能是主动维持的生长素梯度，向转录因子网络发出信号，转录因子网络进而向下游效应器发出信号。转录因子也可以向激素生物合成途径发出反馈信号。
