摘要： 本文通过对不同来源大赖草及其可能供体物种的EST、GOT、SOD同工酶及HMW-GS的分析, 发现不同来源大赖草的同工酶及蛋白图谱呈一定差异,但其中为不同来源大赖草所共有的一些谱带, 同时也存在于具N染色体组物种的分析图谱中,而在具J染色体组的物种中却没有特异性分布,推断大赖草中含有N染色体组,但可能不含J染色体组。
Abstract:The zymogram phenotypes of Esterase(EST),Glutamate oxalocate transminase(GOT),Superoxide dismutase(SOD)and the banding patterns of high molecular weight glutenin subunits(HMW-GS) were determined for different Leymus racemosus accessions and their putative donor species,It was found that although the zymogram phenotypes and the HMW-GS banding patterns appeared polymorphism,common bands for different Lr accessions were found in the species with N genome,but not in those with J genome,suggesting that the Psathyrostachys species with N genome must be phylogenetically closer to Lr,while the Thinopyrum species with J genome are farther to it.
