Root-knot nematodes (RKNs; spp.) engage in complex parasitic interactions with many different host plants around the world, initiating elaborate feeding sites and disrupting host root architecture. Although RKNs have been the focus of research for many decades, new molecular tools have provided useful insights into the biological mechanisms these pests use to infect and manipulate their hosts. From identifying host defense mechanisms underlying resistance to RKNs to characterizing nematode effectors that alter host cellular functions, the past decade of research has significantly expanded our understanding of RKN-plant interactions, and the increasing number of quality parasite and host genomes promises to enhance future research efforts into RKNs. In this review, we have highlighted recent discoveries, summarized the current understanding within the field, and provided links to new and useful resources for researchers. Our goal is to offer insights and tools to support the study of molecular RKN-plant interactions.
根结线虫（RKNs； spp.）与世界各地的许多不同宿主植物进行复杂的寄生相互作用，启动精心设计的取食部位并破坏宿主根系结构。尽管 RKNs 已经成为研究的焦点已有几十年，但新的分子工具为了解这些害虫用于感染和操纵宿主的生物学机制提供了有用的见解。从鉴定对 RKNs 抗性的宿主防御机制到表征改变宿主细胞功能的线虫效应子，过去十年的研究极大地扩展了我们对 RKN-植物相互作用的理解，并且寄生虫和宿主基因组的质量不断提高有望增强未来对 RKNs 的研究工作。在这篇综述中，我们强调了最近的发现，总结了该领域的现有认识，并为研究人员提供了新的有用资源的链接。我们的目标是提供见解和工具，以支持对分子 RKN-植物相互作用的研究。
