一、来自野生种的有用基因小麦几乎在世界各国都是一种重要的主食作物。多种来源的基因,包括亲缘野生资源,已帮助育种工作者使小麦适应了各种差异很大的生长条件——不同的土壤、极端温度和降雨量。番茄是另一种广泛栽培的植物,一个来自加拉帕戈斯岛(Galapagos)的野生亲缘种为它提供的抗盐基因,可使这种作物用三分之一的海水进行灌溉。在朝鲜及邻近的中国和苏联境内发现的一个生长在路旁、 A Useful Gene From Wild Species Wheat is an important staple crop in almost every country in the world. Genes of many origins, including kinship wild resources, have helped breeders adapt their wheat to a wide variety of growing conditions - different soils, extreme temperatures and rainfall. Tomato is another widely cultivated plant. One of the wild relatives from Galapagos is the salt-tolerant gene it provides, allowing it to irrigate with one-third of the seawater. A roadside found in North Korea and neighboring China and the Soviet Union,
