英国园艺研究国际研究所的戴维·詹姆斯教授近日在伦敦举行的英国科学节上说 ,他正与牙科专家合作 ,尝试将一种基因植入水果 ,使水果中产生保护牙齿的物质。伦敦古伊斯医院的专家发现 ,一种特殊的缩氨酸能防止变种链球菌附着在牙齿表面 ,而这种细菌正是引起蛀牙的罪魁祸首。他 Professor David James of the International Institute of Horticultural Research at the British Science Festival in London recently said he is working with dental specialists to try to implant a gene into fruits that produce teeth-protecting substances in fruits.
