氮是植物生存所必需的基本元素，众所周知，豆科植物可以招募根瘤菌来固定大气中的氮。在这种被广泛研究的共生关系中，豆科植物在根上发育出特定的结构来寄主特定的共生体。这篇综述探讨了豆科植物根瘤菌共生之外的交替结瘤结构及其功能，并讨论了结瘤的其他不寻常方面。这包括放线根菌-法兰克菌，苏铁-蓝藻菌，以及非豆科植物的安德氏副asponia -根瘤菌共生。结节也不局限于根，在茎和叶中也有。最近的研究表明，豆类根瘤菌结瘤带来了许多其他好处，有些是直接的，有些是间接的。根瘤菌共生可以导致其他途径的改变，包括防御反应的启动，以及调节或增强对生物和非生物胁迫的抵抗力。有这么多的途径可以探索，这篇综述讨论了最近的发现，并强调了未来的方向在结瘤的研究。
Nitrogen is an essential element needed for plants to survive, and legumes are well known to recruit rhizobia to fix atmospheric nitrogen. In this widely studied symbiosis, legumes develop specific structures on the roots to host specific symbionts. This review explores alternate nodule structures and their functions outside of the more widely studied legume–rhizobial symbiosis, as well as discussing other unusual aspects of nodulation. This includes actinorhizal-Frankia, cycad-cyanobacteria, and the non-legume Parasponia andersonii-rhizobia symbioses. Nodules are also not restricted to the roots, either, with examples found within stems and leaves. Recent research has shown that legume–rhizobia nodulation brings a great many other benefits, some direct and some indirect. Rhizobial symbiosis can lead to modifications in other pathways, including the priming of defence responses, and to modulated or enhanced resistance to biotic and abiotic stress. With so many avenues to explore, this review discusses recent discoveries and highlights future directions in the study of nodulation.
