The relationship between microbial population size and disease in the Arabidopsis thaliana phyllosphere

T. L. Karasov, M. Neumann, A. Duque-Jaramillo, S. Kersten, I. Bezrukov, B. Schroeppel, E. Symeonidi, D. S. Lundberg, J. Regalado, G. Shirsekar, J. Bergelson, D. Weigel

The paper assesses microbial load and composition in Arabidopsis thaliana phyllosphere using shotgun metagenomics, finding high microbial loads correlate with pathogen proliferation and reduced diversity.
