 Abstract 

背景回顾：Infection by multiple pathogens of the same host is ubiquitous in both natural and managed habitats. 

提出问题：While intraspecific variation in disease resistance is known to affect pathogen occurrence, how differences among host genotypes affect the assembly of pathogen communities remains untested.

结果1-长叶车前：In our experiment using cloned replicates of naive Plantago lanceolata plants as sentinels during a seasonal virus epidemic, we find non-random co-occurrence patterns of five focal viruses.

结果2-非随机病原菌发生：Using joint species distribution modelling, we attribute the non-random virus occurrence patterns primarily to differences among host genotypes and local population context.

结论：Our results show that intraspecific variation among host genotypes may play a large, previously unquantified role in pathogen community structure.
