CS、SY和VZ写了这封信。作者负责根据《作者说明》(https://academic.)中所述的政策分发与本文中提出的调查结果相关的材料OUP。Com/plphys/ages/General-Instructions)是:Claus Schwechheimer(Claus.Schwechheimer@wzw。托姆。亲爱的编辑,植物激素和形态生长素基本上调控着从胚胎发生到果实形成的植物发育的所有方面(例如,Moubayidin和Ostergaard,2014;Robert等人,2018)。不均匀或单向的细胞间运输是生长素作用模式的一个重要特性,与局部生长素的生物合成或降解一起,导致生长素最大值和最小值的形成和维持,这对正确的图案形成和发育至关重要(例如,Chen等人,2014;Brumos等人,2018)。典型的“长”PIN形成的生长素输出体(PIN)对于这一功能是必不可少的,因为它们的极性质膜分布和在细胞内的再极化能力使它们非常适合通过简单和复杂的组织定向运输生长素(Bennett,2015)。质膜上极性分布的PIN的丰度,以及调节PIN活性的机制,决定了细胞在给定方向上输出的生长素的绝对量(Barbosa等人,2018年)。关于生长素的极性运输及其在维管分化中的作用的经典研究表明,生长素与其极性运输之间存在正反馈循环(Berleth and Sachs,2001)。一些PIN在同一方向上沿细胞的极性分布表明,一个极性信号可能是生长素本身,促进了PIN的定位,进而促进了生长素的极性运输。2005年,Paciorek等人(2005)报道,生长素可以抑制质膜上的PIN内吞作用,实际上是一般的内吞作用,生长素以这种方式促进自己从细胞外流
CS, SY, and VZ wrote the letter. The author responsible for distribution of materials integral to the findings presented in this article in accordance with the policy described in the Instructions for Authors (https://academic. oup. com/plphys/pages/general-instructions) is: Claus Schwechheimer (claus. schwechheimer@ wzw. tum. de).Dear Editor, The phytohormone and morphogen auxin regulates essentially all aspects of plant development from embryogenesis to fruit formation (eg Moubayidin and Ostergaard, 2014; Robert et al., 2018). 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
