Geneticists in China and the U.S. have sequenced the cucumber genome. This comes on top of the news that the tomato is being sequenced by a 10-nation consortium. But we still have a long way to go before the DNA of my whole salad is sequenced. So far, lettuce has been left out of vegetable sequencing projects, and so has the radish. Never mind pine nuts and parsley.
Researchers hope to use information about the DNA of cucumbers as a window into the molecular workings of a vegetable that shares genes with 800 species, including watermelons, squash and pumpkins. Undoubtedly, this knowledge will be useful in creating ever better cucumbers, though I do wonder how far the sequencing of plants and animals will go. It may also be used to genetically engineer a super-cucumber.
This news is part of a decade of work by scientists sequencing model organisms that include mice, flies, yeast, and a little worm called C. elegans. Among plants, scientists have rice, sorghum and other staple crops.
