三体是重要的细胞遗传学工具,它在植物的遗传定位、连锁分析中起着重要的作用。因此对额外附加染色体的识别是重要的。糖甜菜(Beta Vulgaris)的初级三体系列已经建立,由于糖甜菜细胞学鉴别的诸多困难,因而必须寻找一种新的途径鉴定三体。额外染色体的附加使得同工酶表达受到影响,利用电泳技术检测同工酶图谱而间接鉴定附加染色体的存在是可能的。早在1970年,MeDaniel等利用蛋白质谱带鉴定了大麦的初级三体,发现蛋白质区带数量增减及剂量效应现象。Carlson、Smith
Trisomy is an important cytogenetic tool that plays an important role in the genetic mapping and linkage analysis of plants. Therefore, the identification of additional additional chromosomes is important. The primary trisomies of Beta Vulgaris have been established and due to the many difficulties in the identification of sugar beet cells, a new way must be found to identify trisomies. Addition of extra chromosome makes isoenzyme expression is affected, the use of electrophoresis technology to detect isozyme profiles and indirect identification of additional chromosomes is possible. As early as 1970, MeDaniel et al. Used the protein bands to identify the primary trisomies of barley and found that the number of protein bands increased and the dose-response phenomenon.
