title: [The features of isozyme zymograms and genetic diversity in Undaria pinnatifida].
abstract: The zymogram features of 11 kinds of isozyme and gene expressions in Qingdao and Zhoushan population of U. pinnatifida gametophytes were investigated and genetic diversity was examined by PAGE (polyacrylamide gel electrophoresis) technique. The results showed that the level of genetic diversity in Qingdao population of U. pinnatifida gametophytes was higher than that in Zhoushan population. Two banding patterns controlled by two variant genes were found in alcohol dehydrogenase (Adh) of U. pinnatifida gametophytes. There were null alleles in the population.
