How can growing a crop plant make a field more fertile? With legumes, this is precisely what happens. Working in partnership with symbiotic bacteria that can create root nodules on their chosen host, legumes can fix atmospheric nitrogen and enhance the nitrogen status of soils. How does this symbiosis develop? And how did it evolve? Bacterial and plant genomics are beginning to provide the answers.
种植农作物如何能使田地变得更加肥沃？对于豆类植物而言，情况正是如此。豆类植物与能够在其选定宿主上形成根瘤的共生细菌合作，可以固定大气中的氮并提高土壤的氮含量。这种共生关系是如何发展的？又是如何进化的？细菌和植物基因组学正开始给出答案。
