New paper out of possible interest to those studying the microbiology of the built environment: Frontiers | Beneficial effects of plant-associated microbes on indoor microbiomes and human health? | Frontiers in Plant-Microbe Interaction. The paper makes some arguments regarding possible connections between indoor plant microbiomes and human health. I am posting this here without commentary in the hopes that others will look the paper over and make some comments. Any opinions out there on this?
