Happy Thanksgiving! My inbox was full of exciting new papers, so here is a digest before I start cooking.

Microbiota and epigenetics, predatory bacteria to control infection, bacteria control water levels in leaves, microbial volatile compounds affect plant growth, the invertebrate virome, and natural products as mediators of disease.
