This study provides important new insights into the structural diversity of effectors - proteins secreted by pathogens and symbionts into host cells - from the plant-associated fungus Fusarium oxysporum f. sp. lycopersici. The study provides a convincing approach to understand how effectors navigate their host environment using both computational and experimental approaches to understand how their structure influences binding partners. The work will be of interest to those studying molecular host-microbe interactions and disease protection.
