The ecology and evolution of polyploid niches: investigating the interaction of ploidy, microbiomes, and pathogens.

Polyploidy or whole-genome duplication (WGD) is a ubiquitous phenomenon in the evolutionary history of land-plants. As WGD often induces many new novel, adaptive, or transgressive phenotypes, it can have cascading ecological effects on biotic interactions and potentially the microbiome. There is a growing body of research on the impact that microbiome plays in plant ecology, but few studies have looked at the potential interactions between ploidy, microbiomes, and pathogens in shaping the ecology of newly established polyploids. This study uses synthetic auto-tetraploid Arabidopsis accessions and a synthetic microbiome representative of natural commensal phyllosphere bacteria in order to assay how these interactions impact host phenotype with respect to pathogen response.
