Decaffeinated coffee will be available

Coffee plants, which contain almost no caffeine, will soon provide a drink that can be drunk in the middle of the night but does not keep people awake. John from Hawaii State University. Stiles told New Scientist magazine: "it is estimated that about 20 months later, we will taste this decaffeinated coffee."

The transgenic plant has been cultivated in his laboratory as a tissue culture. He plans to plant the culture in the greenhouse this year. Not long ago, Stiles and his colleagues discovered a gene essential for the early formation of caffeine. They disable the gene by turning off the gene switch. They then used a bacterium to insert a piece of genetic material exactly the same as the major gene, the so-called antisense gene, into the plant's embryonic tissue. As a result, they found that the whole plant produced less caffeine.

Currently growing coffee beans contain only 3% of the normal amount of caffeine. He believes that the basic ingredient of this irritant is produced in various parts of the coffee plant and later concentrated on coffee beans.
