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.
