Eleven wheat-Elytrigia intermedium alien disomic addition lines DAL1,2,3,4,5,6,7,8,9,10 and 11 were characterized with Sod isozyme markers and RAPD markers.

Using the method of SOD suppressing the reduction of NBT in fluorescence by Electro-focusing PAGE,the SOD isozyme in the pollen of sesame,Lotus and Camellia was isolated and intravitally stained.

Expressions of SOD isozyme in different tissues of Procambarus clarkia were comprehended,in order to provide references for the study on inheritance of Procambarus clarkia.

In order to study the antioxidant effects of daidzein,we analyzed the SOD isoenzymes and LDH isoenzymes in the brain of aged mice by polyacylamide gel electrophoresis (PAGE).

originated mainly from middle and lower reaches of Yangtze River valley were collected and cultivated in Weigang Experimental Farm of Nanjing Agricultural University with same cultural method, which zymogram phenotypes of easterase(EST) and superoxide dismutase(SOD) from the laminas sampled in same growth period were compared by using PAGE.

) including 17 parents of hybrid rice, 3 new plant type lines and 22 Nuda and javanica cultivars was analyzed to study the relation of temperate japonica to Nuda and javanica and to explore the possibility of utilizing the genetic difference detected with isozyme markers in hybrid rice breeding.
