DNA sequencing has confirmed that a lot of the coffee you drink is from one of the least genetically diverse crops in the world, making it particularly vulnerable to extinction.
Arabica beans ( Coffea arabica) make up about 60 per cent of the world’s coffee production. “Arabica is the most valuable and highest quality coffee, but it is severely endangered by climate change,” says Simone Scalabrin at IGA Technology Services in Italy.
Scalabrin and his colleagues used whole genome sequencing to look at …
