She says combining many different genes into one plant without genetic engineering requires a lot of plant breeding.
还有一句：That way they avoided the costs as well as the problems connected with getting permission to plant genetically engineered crops.
翻译吗？大意是这样的She says combining many different genes into one plant without genetic engineering requires a lot of plant breeding.她说不用遗传工程把很多不同的基因合成到一个植物中的话，需要一定量的植物繁殖。That way they avoided the costs as well as the problems connected with getting permission to plant genetically engineered crops.这种方式避免了关系到得到种植遗传工程庄稼的许可的问题
