Nematodes form an important part of soil biodiversity as the most abundant and functionally diverse animals affecting plant performance. Most studies on plant-nematode interactions are focused on agriculture, while plant-nematode interactions in nature are less known. Here we highlight that nematodes can contribute to vegetation dynamics through direct negative effects on plants, and indirect positive effects through top-down predation on plant-associated organisms. Global change alters these interactions, of which better understanding is rapidly needed to better predict functional consequences. By expanding the knowledge of plant-nematode interactions in natural systems, an increase in basic understanding of key ecological topics such as plant-soil interactions and plant invasion dynamics will be obtained, while also increasing the insights and potential biotic repertoire to be applicable in sustainable plant management.
线虫作为影响植物性能的最丰富和功能最多样化的动物，是土壤生物多样性的重要组成部分。大多数关于植物-线虫相互作用的研究都集中在农业上，而自然中植物-线虫相互作用的了解较少。在这里，我们强调线虫可以通过直接对植物产生负面影响，以及通过对植物相关生物的自上而下的捕食产生间接的积极影响，从而促进植被动态。全球变化改变了这些相互作用，因此需要更好地理解这些相互作用，以便更好地预测其功能后果。通过扩大对自然系统中植物-线虫相互作用的认识，可以增加对关键生态主题的基本理解，例如植物-土壤相互作用和植物入侵动态，同时还可以增加适用于可持续植物管理的见解和潜在生物组合。
