Arabica genome sequenced in US

Researchers in the US have sequenced the genome for Coffea Arabica as part of the effort to combat the effects of climate change on global coffee production. While this is not the first instance of the coffee genome being sequenced, it is the first time the data has been made publicly available. Now available for immediate use by scientists and plant breeders around the world, the new genome sequence has been posted to, the public database for comparative plant genomics coordinated by the US Department of Energy’s Joint Genome Institute. “This new genome sequence for Coffea arabica contains information crucial for developing high-quality, disease-resistant coffee varieties that can adapt to the climate changes that are expected to threaten global coffee production in the next 30 years,” said Juan Medrano, a geneticist in the UC Davis College of Agricultural and Environmental Sciences and co-researcher on the sequencing effort. “We hope that the C. arabica sequence will eventually benefit everyone involved with coffee — from coffee farmers, whose livelihoods are threatened by devastating diseases like coffee leaf rust, to coffee processors and consumers around the world,” he said. The sequencing was conducted through a collaboration between Medrano, plant scientists Allen Van Deynze and Dario Cantu, and postdoctoral research scholar Amanda Hulse-Kemp, all from UC Davis.
