Among plant-microbe interactions, root nodule symbiosis is one of the most important beneficial interactions providing legume plants with nitrogenous compounds. Over the past years a number of genes required for root nodule symbiosis has been identified but most recently great advances have been made to dissect signalling pathways and molecular interactions triggered by a set of receptor-like kinases. Genetic and biochemical approaches have not only provided evidence for the cross talk between bacterial infection of the host plant and organogenesis of a root nodule but also gained insights into dynamic regulation processes underlying successful infection events. Here, we summarise recent progress in the understanding of molecular mechanisms that regulate and trigger cellular signalling cascades during this mutualistic interaction.
在植物-微生物相互作用中，根瘤共生是最重要的有益相互作用之一，为豆科植物提供含氮化合物。在过去的几年中，已经鉴定出许多根瘤共生所必需的基因，但最近在解析由一组类受体激酶触发的信号转导途径和分子相互作用方面取得了重大进展。遗传和生化方法不仅为宿主植物的细菌感染与根瘤器官发生之间的串扰提供了证据，而且深入了解了成功感染事件背后的动态调控过程。在这里，我们总结了在理解调节和触发这种互利共生相互作用过程中细胞信号级联的分子机制方面的最新进展。
