Vesicular trafficking is mediated by distinct exocytic and endocytic routes in eukaryotic cells. These pathways involve RAB family proteins, ADP-ribosylation factor, RHO proteins of the Ras superfamily, and SNAREs (soluble N-ethylmaleimide-sensitive factor adaptors). Studies have shown that vesicular trafficking plays a crucial role in protein localization and movement, signal transduction, and multiple developmental processes. Here we summarize the role of vesicular trafficking in root and root hair growth and in auxin-mediated root development, focusing on the regulation of the polarized subcellular distribution of the PIN proteins (auxin efflux carriers).
囊泡运输是真核细胞中通过不同的胞吐和胞吞途径来介导的。这些途径涉及 RAB 家族蛋白、ADP-核糖基化因子、Ras 超家族的 RHO 蛋白和 SNARE（可溶性 N-乙基马来酰亚胺敏感因子附着蛋白）。研究表明，囊泡运输在蛋白质定位和运动、信号转导以及多种发育过程中起着至关重要的作用。在这里，我们总结了囊泡运输在根和根毛生长以及生长素介导的根发育中的作用，重点介绍了 PIN 蛋白（生长素外排载体）的极性亚细胞分布的调节。
