摘要:

外来植物入侵是世界各地所面临的重要生态安全问题, 外来植物入侵的过程受到包括自身的耐受性、其他生物与非生物因素(降水、温度和土壤养分等)的综合影响。其中, 植物与微生物互作对植物的生长发育和种间竞争等具有重要调控作用。现有研究表明, 本地植物与不同种类土壤微生物的互作对单一物种入侵存在的影响途径包括: 1)本地植物受到病原微生物积累的负面效应更大, 从而增进外来植物的入侵优势; 2)本地植物与共生微生物的互利共生关系有助于其抵御外来植物的入侵, 而外来植物入侵时本地植物与共生微生物之间共生关系的改变则有利于外来植物入侵; 3)具有高养分利用率的外来植物能从腐生微生物的分解过程中获取更多营养, 从而扩大自身的竞争优势。相比于单一物种入侵, 多物种同时入侵可通过种间协同作用分担病原菌压力、与微生物建立共生关系、加速腐生微生物分解过程获取异质性营养等对本地植物形成更大的竞争压力, 并干扰本地植物与土壤微生物互作的平衡。另外, 在全球变化影响下, 本地植物受到来自土壤微生物的负面影响增大, 也能加速外来植物的入侵进程。该文综述了近年来本地植物与土壤微生物的互作对外来植物入侵影响的最新研究进展, 并展望了未来的研究方向和重点。

Abstract:

Alien plant invasions pose a significant threat to global ecological security. Various factors, including the ecological tolerance of alien plants and their interactions with biotic and abiotic elements such as rainfall, temperature, and soil nutrients, influence the dynamics of plant invasions. The interaction between plants and various micro-organisms plays an important role in regulating plant growth, development, and interspecific competition. Previous studies indicate that the interactions between native plants and different groups of soil microorganisms affect plant invasion through several pathways: 1) Pathogenic microorganisms may have more suppressive effects on native plants, facilitating the invasion of alien plants. 2) Symbiotic microorganisms can help native plants resist alien plant invasion, but disrupting these mutualistic associations may accelerate invasion. 3) Additionally, saprophytic microbiota may promote plant invasions by increasing the rate of nutrient cycling and facilitating these alien plants with high nutrient utilization efficiency. Compared to single-species invasions, multispecies invasions can increase invasive capacity through shared pathogen pressures, forming symbioses, and utilizing heterogeneous nutrients from saprophytic microorganisms. This interspecific synergistic effect can disrupt the balance between native plants and soil microbes. Furthermore, global changes may promote alien plant invasions through the detrimental effects of soil microbes on native plants. This review examines the impact of interactions between native plants and soil microbes on plant invasions and outlines directions for future research.
