Endophytic microbiome in crowberry? What?

I have to admit. I had to look up what endophytic micro biome was, but it is truly fascinating. They are microbes that live inside plant tissues, in this case, the crowberry, Empetrum nigrum. The authors identified one of these microbes inside the crowberry that has antibacterial activity, specifically a Staphylococcus bacterium. They propose that the presence of this endophyte might have value in the pharmaceutical industry to fight bacterial diseases. So the crowberry itself is not antibacterial. It’s a litter microbe inside the tissues!
