Global diversity of phytoplasma-host associations

Project Overview

Phytoplasmas are obligate bacterial pathogens transmitted by insect vectors and infecting hundreds of plant species worldwide. Despite their global impact, large-scale patterns of host association remain poorly understood.

Research Questions

• How structured are phytoplasma–host networks globally?
• Do host shifts follow phylogenetic constraints?
• How does biogeography influence network structure?

Approach

We integrate global occurrence databases, natural areas global screening project in our lab, and ecological network modeling to quantify large-scale patterns of host association.

Broader Impact

Understanding phytoplasma host associations improves prediction of pathogen emergence and informs agricultural management strategies.
