An international team of researchers from institutions including Nanyang Technological University, Singapore, Nestlé, Université de Montpellier, and the University at Buffalo has achieved a breakthrough in combating coffee leaf rust in Arabica plants by mapping the genomes of Arabica and its relatives, Robusta and C. eugenioides. This research, published in Nature Genetics by Jarkko Salojärvi et al., has identified genes that confer resistance to the disease, offering hope for breeding new, more resilient Arabica varieties. The study not only provides the most detailed Arabica genome reference to date but also traces the origin of Arabica coffee to a cross-pollination event between Robusta and C. eugenioides around 350,000 to 610,000 years ago. This genomic insight is expected to facilitate the development of Arabica coffee plants with improved disease resistance, drought resilience, and crop yield, without sacrificing the beloved aroma and taste, thereby ensuring the sustainability of the global coffee industry which supports the livelihoods of 125 million people.

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 ...
