Since molecular phylogenetics recognized root nodule symbiosis (RNS) of all lineages as potentially homologous, scientists have tried to understand the "when" and the "how" of RNS evolution. Initial progress was made on understanding the timing of RNS evolution, facilitating our progress on understanding the underlying genomic changes leading to RNS. Here, we will first cover the different hypotheses on the timings of gains/losses of RNS and show how this has helped us understand how RNS has evolved. Finally, we will discuss how our improved understanding of the genetic changes that led to RNS is now helping us refine our understanding on when RNS has evolved.
由于分子系统发育学认为所有谱系的根瘤共生（RNS）可能具有同源性，科学家们一直试图了解RNS进化的“时间”和“方式”。在理解RNS进化的时间方面取得了初步进展，这促进了我们在理解导致RNS的潜在基因组变化方面的进展。在这里，我们将首先介绍关于RNS获得/丧失时间的不同假说，并说明这如何帮助我们理解RNS是如何进化的。最后，我们将讨论我们对导致RNS的基因变化的深入理解如何现在正帮助我们完善对RNS进化时间的理解。
