Arabica coffee, the most economically important coffee globally, accounts for 60% of coffee products worldwide. However, the plants it hails from are vulnerable to a fungal disease called coffee leaf rust, which devastated Sri Lanka’s coffee empire in the 1800s. An international team of researchers co-led by Nanyang Technological University, Singapore (NTU Singapore) has made a breakthrough that helps protect Arabica plants against this disease. The study, published in Nature Genetics, [...]

That coffee you slurped this morning? It’s 600,000 years old. Using genes from coffee plants around the world, researchers built a family tree for the world’s most popular type of coffee, known to scientists as Coffea arabica and to coffee lovers simply as “arabica.” The researchers, hoping to learn more about the plants to better protect them from pests and climate change, found that the species emerged around 600,000 years ago through natural crossbreeding of two [...]

Coffee, the fuel that keeps the world running, comes from a plant called Coffea arabica. Scientists at the University of Buffalo (UB) have created an incredibly detailed map of the DNA of Arabica coffee, which acts as a blueprint for the plant, revealing its complex ancestry. Arabica coffee is not the product of a single, isolated lineage but rather the result of a natural hybridization event between two different coffee species: Coffea canephora (commonly known as Robusta) and Coffea [...]
