摘要
用聚丙烯酰胺凝胶电泳（PAGE）技术对裙带菜（Undariapinnatifida）丝状体青岛种群和舟山种群的11种同工酶酶谱特征及其基因表达进行了研究，并作了遗传多样性的检测分析。结果表明：裙带菜丝状体青岛种群遗传多样性水平高于舟山种群：裙带菜丝状体种群还存在哑基因；另外，在裙带菜丝状体的乙醇脱氢酶酶谱中发现2个变异基因控制的2条酶带。
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. pinnated gametophytes. There were null alleies in the population.
