The plant hormone auxin plays a crucial role in the upstream regulation of many processes, making the study of its action particularly interesting to understand plant development. In this review we will focus on the effects auxin exerts on cell cycle progression, more specifically, during the initiation of lateral roots. Auxin fulfils a dominant role in the initiation of a new lateral root primordium. How this occurs remains largely unknown. Here we try to integrate the classical auxin signalling mechanisms into recent findings on cell cycle regulation. How both signalling cascades are integrated appears to be complex and is far from understood. As a means to solve this problem we suggest the use of a lateral root‐inducible system that allows investigation of the early signalling cascades initiated by auxin and leading to cell cycle activation.
