Scientists find common genes defending coffee plants against devastating disease

by Nanyang Technological University

Arabica coffee is the most economically important coffee globally and accounts for 60% of coffee products worldwide. But the plants it hails from are vulnerable to a disease that, in the 1800s, devastated Sri Lanka's coffee empire.

Now, an international team of researchers co-led by Nanyang Technological University, Singapore (NTU Singapore) has made a breakthrough that helps protect Arabica plants (Coffea arabica) against the fungal disease, called coffee leaf rust.

The other co-leads of the study, published in Nature Genetics, are based at the world's largest food and beverage company Nestlé, the Université de Montpellier in France and the University at Buffalo in the United States.

The scientists mapped out, in great detail, all the genetic material—or genomes—of Arabica and two related coffee plants. This allowed the team to identify a new combination of genes shared by the plants that are resistant to coffee leaf rust. With the data on the genomes, other useful traits in coffee plants can also be identified.
