小麦有一套缺体系列,它的同工酶基因定位常常是利用缺体作材料。因为缺失某对染色体的小麦同时又缺少某一条同工酶带,所以,可确定此同工酶带的基因即位于所缺失的染色体上。但这种方法确定的基因所在的染色体不是对所有作物都能适用。如玉米的缺体不能存活,至今玉米同工酶基因的位置仍未测定。我们利用一种新的方法:选择易于清楚识别基因位置的性状作为标记,用具有标记性状
Wheat has a set of missing body series, its isozymes gene mapping is often the use of lack of body material. Because the absence of a pair of chromosomes of wheat at the same time lacking an isozyme band, it can be determined that the isozyme band of the gene that is located in the missing chromosome. However, the chromosomes identified by this method are not suitable for all crops. As the absence of maize can not survive, so far the location of the corn isozyme gene has not been determined. We use a new approach: selecting traits that clearly identify the location of the gene as markers, markers with traits
