【Share】GENOME-ANNIVERSARY~~Genetic Engineering Brings Cloned Crops Closer
|
|
Seeds genetically identical to parent plant could revolutionize agriculture. The production of exact genetic replicas of important food crops has come a step closer. By combining mutations that abolish the shuffling of genes during sexual reproduction, researchers have sexually reproducing plants to clone themselves through seeds. The method, published today in Science, has so far only been tested in the model plant Arabidopsis thaliana (thale cress ), but lead author Raphael Mercirer of the French National Institute for Agricultural Research in Versailles says his lab is working to extend the findings to crops. Such an advance could allow farmers to progate their own crops, rahther than buying seed each year. It would also speed up the time it takes for companies to generate new plant breeds. Some in the field are already confident that the technique will find its way into agricultural use. "This is a new breeding tool," says Peter van Dijk, a plant geneticist at the plant breeding company KeyGene, in Wageningen, the Netherlands. " It opens up a whole new field." |
