10、l intestine(肠).Many others may have milder gluten intolerance and avoid foods that contain it.Most gluten-free bread is made from alternative flours such as rice or potato，so it tastes and feels different from wheat bread.Now，however，researchers say that they have found a way to genetically engineer
11、 wheat that contains far less of the most troublesome type of glutenbut still has other proteins that give bread its characteristic taste and springiness.Genetically modified crops are the subject of fierce debate around the world.The biggest concern involves the practice of inserting DNA from one s
12、pecies into another，says Francisco Barro，a plant biotechnologist.To avoid this genetic crossover，Barro and his colleagues used the gene-editing technique CRISPRCas9 to cut selected genes from a wheat genome(基因组).Their study zeroed in on alpha-gliadins(-胶质蛋白)，gluten proteins believed to be wheats maj
13、or troublemakers in the immune system.The researchers designed bits of genetic material that directed the scissor-like Cas9 protein to cut out 35 of the 45 alphagliadin genes.When the modified wheat was tested in a Petri dish，it produced an 85 percent weaker immune response，the team reported online
14、last September in Plant Biotechnology Journal.Wendy Harwood，a crop geneticist at the John Innes Center in England，who was not part of the study，notes that the engineered wheat has a long way to go before it can be turned into anything marketable.“I dont think its the end of the story.”she says.“This
15、 is just a really important step in maybe producing something that is going to be incredibly useful.”To develop a completely safe strain of wheat for celiac patients，the researchers may need to target more of the gluten genes.Barro says his team is working on that.1、Whats the text mainly about?AMaking glutenfree bread.BAdvantages of
