The development of host-microbe interactions between legumes and their cognate rhizobia requires localization of the bacteria to productive sites of initiation on the plant roots. This end is achieved by the motility apparatus that propels the bacterium and the chemotaxis system that guides it. Motility and chemotaxis aid rhizobia in their competitiveness for space, resources, and nodulation opportunities. Here, we examine studies on chemotaxis of three major model rhizobia, namely , , and , cataloging their range of attractant molecules and correlating this in the context of root and seed exudate compositions. Current research areas will be summarized, gaps in knowledge discussed, and future directions described.
豆科植物与其同源根瘤菌之间宿主 - 微生物相互作用的发展需要细菌定位于植物根上的有效起始位点。这一目标是通过推动细菌的运动装置和引导细菌的趋化系统来实现的。运动性和趋化性有助于根瘤菌在空间、资源和结瘤机会方面的竞争。在这里,我们研究了三种主要模式根瘤菌(即[此处原文缺失具体菌名]、[此处原文缺失具体菌名]和[此处原文缺失具体菌名])的趋化性研究,列出它们吸引分子的范围,并在根和种子分泌物组成的背景下进行关联。将总结当前的研究领域,讨论知识空白,并描述未来的方向。
