| 摘 要： | 1 INTRODUCTION Since isoenzyme was first named by Markert and M?ller in 1957 (Hu and Wan, 1985), the separa- tion of isoenzyme has been rapidly developed. Isoenzymes is an important tool for studying life in molecule level. Isoenzymes are transcribed by g…

| Abstract: | The authors compared isoenzymes of five enzymes and soluble protein in Arthrospira platensis (A3) and A. erdosensis (A4) from alkaline lakes in Erdos Plateau, Nei Monggo (Inner Mongalia), China and exotic species of A. platensis (A1) from Chad and A. maxima (A2) from Mexico by means of polyacrylamide gel electrophoresis. The results showed that the isoenzymes of EST, POD and soluble protein were polymorphic. Monomorphism and polymorphism were found in isoenzymes of AMY, CAT and SOD, and monomorphism was found only in the introduced species. The isoenzymes and soluble protein of the local species are all polymorphic. The number of bands in these species were in the order of A3>A4>A1>A2. A2 is the most primary, A1 from Chad Lake is relatively primary, A3 and A4 are ad- vanced species in evolution. Cluster analysis showed that the relation between the two introduced species are the closest to each other, and so too are the two local ones. |
