Uneven or unidirectional cell-to-cell transport is an important property of auxin’s mode of action and, together with local auxin biosynthesis or degradation, result in the formation and maintenance of auxin maxima and minima pivotal for proper patterning and development (eg Chen et al., 2014; Brumos et al., 2018). Canonical “long” PIN-FORMED auxin exporters (PINs) are essential for this function because their polar plasma membrane distribution and their ability to repolarize within a cell make them ideal to directionally transport auxin through simple and complex tissues (Bennett, 2015). The abundance of polarly distributed PINs at the plasma membrane, together with mechanisms regulating PIN activity, determines the absolute amount of auxin being exported from a cell in a given direction (Barbosa et al., 2018). Classical studies on polar auxin transport and its role in vascular differentiation have suggested a positive feedback loop between auxin and its polar transport (Berleth and Sachs, 2001). The polar distribution of some PINs in the same orientation along cell files suggested a polar signal, which could be auxin itself, facilitates PIN localization and, in turn, polar auxin transport. In 2005, Paciorek et al.(2005) reported that auxin could inhibit PIN endocytosis, and in fact endocytosis in general, from the plasma membrane and that auxin in this way promoted its own efflux from cells
