Narrow, but not broad, spectrum resistance and disease reshape phyllosphere bacterial communities
A. F. Bigott, S. F. F. Hutton, G. Vallad, R. Lankau, J. D. Barak
This study examines how transgenic resistance genes in tomato plants affect phyllosphere bacterial communities during disease, finding that ETI resistance significantly alters these communities while PTI resistance does not.

Xanthomonas infection transforms the apoplast into an accessible and habitable niche for Salmonella enterica
M. H. Dixon, K. N. Cowles, S. C. Zaacks, I. N. Marciniak, J. D. Barak
This study shows that Xanthomonas infection creates an aqueous apoplast that allows Salmonella enterica to survive and replicate, transforming an inhospitable leaf environment into a habitable niche for the bacteria.
