“I would like to see a much larger study with a larger sampling,” he said. “It’s easy to find feral samples, but these are not wild types,” Dr. Fumagalli said. The study was led by Ren Guangpeng, a botanist at Lanzhou University in the western Chinese province of Gansu. To conduct the study, Dr. Ren and his colleagues collected 82 samples, either seeds or leaves, from around the world. Dr. Fumagalli and his colleagues then extracted genomic DNA from the samples and sequenced them in a lab in Switzerland.
