Abstract
Pathogen detection generally occurs when a host-adapted microbe grows to high densities and exhibits a high rate of transmission. Since agricultural landscapes provide excellent conditions for pathogen spread and detection, our understanding of host specialisation and virulence evolution is heavily informed by disease outbreaks in crop plants. Expanded sampling and sequencing programs now capture greater population and community-level variation in both focal and peripheral hosts. What does this tell us about the processes and mechanisms underlying pathogen emergence and adaptation? I will discuss this question in the context of recent findings from our work investigating the origins of distinct outbreak events caused by members of the Ralstonia solanacearum and Pseudomonas syringae species complex.
