A genetically modified coffee bush that produces decaffeinated beans that have all the qualities of ordinary coffee has been developed by Japanase scientists.
A report in Nature today said geneticists from the Nara Institute of Science and Technology have found a way of stifling the gene that naturally makes one of three enzymes that go into making caffeine. And in laboratory results the plants were engineered to yield 70% less caffeine than in the coffee bean.
