Both bottom-up and top-down processes modulate plant communities. Fungal and oomycete pathogens are most common in global grasslands, and due to differences in their physiology, function, host range, and life cycles, they may differentially affect plants (in both intensity and direction). However, how fungal and oomycete pathogens regulate bottom-up and top-down effects on plant community biomass remains unclear.

- Microbial mutualists, like arbuscular mycorrhizal fungi (AMF), can significantly influence the ecology and evolution of host plants and their interactions with pathogens.
- A meta-analysis of 130 comparisons across 69 studies found that AMF inoculation generally decreases the incidence and severity of aboveground plant diseases, specifically reducing necrotrophic diseases but not biotrophic ones.
- Experiments showed that these effects might stem from AMF's regulation of key signaling pathways in plants, alongside potential changes in plant nutrition and defense compounds, highlighting the need to consider pathogen types when studying these interactions.
