| 摘 要： | 对 Glu-1基因的Glu-Al和Glu-Bl位点都发生突变的1个小麦体细胞无性系后代的高分子量谷蛋白亚基组成进行的分析结果,进一步证实了体细胞无性系发生了基因突变, 且发现同源染色体的等位基因易发生相同突变,突变体多是纯合基因型。认为这是体细胞无性系变异稳定快的遗传根源。
Abstract:Evidence for specific gene mutation has been obtained in our previous research by analyzing high-molecular-weight glutenin subunits(HMW-GS)controlled by Glu-1 gene in wheat somaclons.On the basis of the result,the present study detected in the offspring of a HMW-GS somaclone the mutants at both Glu-A1 and Glu-B1 loci.The occurrence of gene mutation in wheat somaclones was further proved.The results showed that a allele on homologous chromosomes often mutated identically.Genotype of this kind mutation migh be pure.Thie is considered to be genetic reason for quickly stabilizing of somaclonal variation.
