When the rust settles: Uncovering the movements of coffee leaf rust disease

Researchers have found a high incidence of coffee leaf rust (CLR) disease in Vietnam, the world's second-largest coffee producer. Potential origins and migration routes were revealed, as well as a close genetic relationship with several Central and South American rust fungus populations. These findings will help to predict future spread of CLR, and highlight the need to consider seedling sources and human activities in CLR management.
