- The microbial symbionts of eukaryotes influence disease resistance in many host-parasite systems. Symbionts show substantial variation in both genotype and phenotype, but it is unclear how natural selection maintains this variation. It is also unknown whether variable symbiont genotypes show specificity with the genotypes of hosts or parasites in natural populations. Genotype by genotype interactions are a necessary condition for coevolution between interacting species. Uncovering the patterns of genetic specificity among hosts, symbionts, and parasites is therefore critical for determining the role that symbionts play in host-parasite coevolution. Here we show that the strength of protection conferred against a fungal pathogen by a vertically-transmitted symbiont of an aphid is influenced by both host-symbiont and symbiont-pathogen genotype by genotype interactions. Further, we show that certain symbiont phylogenetic clades have evolved to provide stronger protection against particular pathogen genotypes. However, we found no evidence of reciprocal adaptation of co-occurring host and symbiont lineages. Our results suggest that genetic variation among symbiont strains may be maintained by antagonistic co-evolution with their host and/or their host's parasites.
- Complete experimental data[1] Sporulation data for the G_symbiont x G_pathogen experiment. Each line represents one aphid harboring a particular symbiont ("Symbiont_Genotype") infected with the fungal pathogen Pandora neoaphidis ("Fungal_Genotype"). A "0" indicates that the aphid did not produce a sporulating cadaver, a "1" indicates that the aphid sporulated. [2] Survival data from the same experiment (G_symbiont x G_pathogen) (control aphids only). The columns day and survival form the Surv object for survival analysis: status indicates the aphid was alive (0) or dead (1) on a given day. [3] Sporulation data for the G_symbiont x G_host experiment. Aphid genotype ("Host.Genotype") and symbiont genotype ("Symbiont.Genotype") are indicated. As above, each line represents an individual aphid, with a "0" indicating that the aphid did not produce a sporulating cadaver, a "1" indicating that the aphid sporulated.data_complete.xlsx
