• Interactions between individual plant pathogens and their environment have been described many times. However, the relative contribution of different environmental parameters as controls of pathogen communities remains largely unknown.
• Here we investigate the importance of environmental factors, including geomorphology, climate, land use, soil and plant community composition, for a broad range of aboveground and belowground fungal, oomycete and bacterial plant pathogens.
• We found that plant community composition is the main driver of the composition and richness of plant pathogens after taking into account all other tested parameters, especially those related to climate and soil.
• In the face of future changes in climate and land use, our results suggest that changes in plant pathogen community composition and richness will primarily be mediated through changes in plant communities, rather than the direct effects of climate or soils.

植物病原体组成和丰富度的环境和植物群落驱动因素

• 单个植物病原体与其环境之间的相互作用已被多次描述。然而，不同环境参数作为病原体群落控制的相对贡献仍然很大程度上未知。
• 在这里，我们调查了环境因素对广泛的地上和地下真菌、卵菌和细菌植物病原体的重要性，包括地貌、气候、土地利用、土壤和植物群落组成。
• 我们发现，在考虑所有其他测试参数，特别是与气候和土壤相关的参数后，植物群落组成是植物病原体组成和丰富度的主要驱动因素。
• 面对未来气候和土地利用的变化，我们的研究结果表明，植物病原体群落组成和丰富度的变化将主要通过植物群落的变化来调节，而不是气候或土壤的直接影响。
