Plant receptor complexes at the cell surface perceive many different external and internal signalling molecules and relay these signals into the cell to regulate development, growth and immunity. Recent progress in the analyses of receptor complexes using different live cell imaging approaches have shown that receptor complex formation and composition are dynamic and take place at specific microdomains at the plasma membrane. In this review we focus on three prominent examples of Arabidopsis thaliana receptor complexes and how their dynamic spatio-temporal distribution at the PM has been studied recently. We will elaborate on the newly emerging concept of plasma membrane microdomains as potential hubs for specific receptor complex assembly and signalling outputs.
植物细胞表面的受体复合物可感知许多不同的外部和内部信号分子，并将这些信号传递到细胞内，以调节发育、生长和免疫。最近使用不同的活细胞成像方法对受体复合物进行分析的进展表明，受体复合物的形成和组成是动态的，并且发生在质膜的特定微区。在这篇综述中，我们重点关注拟南芥受体复合物的三个突出例子，以及最近如何研究它们在质膜上的动态时空分布。我们将详细阐述质膜微区这一新出现的概念，它是特定受体复合物组装和信号输出的潜在中心。
