Genetically modified coffee could be just around the corner

A consortium of scientists announced Thursday in Science that they've sequenced the coffee genome for the first time. By determining all of the genes that make up robusta coffee, a plant variety that accounts for about one-third of the world's consumption, they've opened the door to better breeding practices and even genetic engineering.

The researchers were most surprised by the genes used to produce caffeine. There are several theories as to why a plant would want to give its leaves and berries an energy buzz: It might be meant as a deterrent against leaf-eating bugs, to make surrounding soil less hospitable to rival seedlings, or...
