Abstract
From embryogenesis to fruit formation, almost every aspect of plant development and differentiation is controlled by the cellular accumulation or depletion of auxin from cells and tissues. The respective auxin maxima and minima are generated by cell-to-cell auxin transport via transporter proteins. Differential auxin accumulation as a result of such transport processes dynamically regulates auxin distribution during differentiation. In this review, we introduce all auxin transporter (families) identified to date and discuss the knowledge on prominent family members, namely, the PIN-FORMED exporters, ATP-binding cassette B (ABCB)-type transporters, and AUX1/LAX importers. We then concentrate on the biochemical features of these transporters and their regulation by posttranslational modifications and interactors.
摘要
从胚胎发生到果实形成，植物发育和分化的几乎每一个方面都受到细胞和组织中生长素的积累或耗尽的控制。相应的生长素最大值和最小值是通过转运蛋白的细胞间生长素运输产生的。这种运输过程导致的生长素差异积累，动态调节分化过程中的生长素分布。在这篇综述中，我们介绍了迄今为止鉴定的所有生长素转运体（家族），并讨论了主要家族成员的知识，即 PIN 形成外排体、ATP 结合盒 B（ABCB）型转运体和 AUX1/LAX 进口器。然后，我们专注于这些转运体的生化特征及其通过翻译后修饰和相互作用的调节。
