Biochemical Study on the Genome Constitutions of Leymus racemosus
大赖草染色体组构成的生化分析 Biochemical Study on the Genome Constitutions of Leymus racemosus

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 do nor species. It was found that although the zymogram phenotypes and the HMW-GS banding patterns appeared polymorphism, common bands for different Lr accessions wcre 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.
