查询词典 polymorphism

Psychrophilic and psychro-tolerant bacteria were cultured and used for screening the cold-active enzymes. Some characteristics of cold-active protease and chitinase were analyzed then. Microbial 16S rDNA clone libraries of deep sea sediments were constructed and studied by PCR-RFLP (Restriction Fragment Length Polymorphism) and phylogenetic analysis based on 16S rDNA sequences.

通过构建沉积物中微生物16S rDNA克隆文库，采用PCR-RFLP分析、DNA-DNA杂交、16S rDNA序列测定以及系统发育分析的方法，研究了西太平洋&暖池&区和东太平洋&结核&区两个不同海区深海沉积物中的微生物多样性和群落结构特征及其与环境的相互关系，得到了一些与&暖池&区环境特点紧密相关的新发现，新认识。

Results (1) From more than 100 primers, 11 primers producing polymorphism and reproduceable bands were selected, 129 bands were amplified.(2) The percentage of polymorphic bands within different populations were 20.9%-55.0%.(3) The cluster map including all samples were obtained by UPGMA. In the map, there were six cluster groups and three individuals outside the groups. The branch with five samples of Zhongjiang Sichuan population were far from other samples in genetic distance.(4) According to the distribution provinces five groups were divided in genetic variance analysis. Genetic variance 80.44% existing within population, 8.29% among populations and 11.27% among groups.

结果 （1）从100多个引物中选择出11个多态性强和重复性好的引物，扩增得到129条带；（2）不同居群内多态位点比率为20.9%－55.0%；（3）用UPGMA法得到所有样本的聚类图，可分为6个主要分支组和3个组外个体，其中四川中江居群的5个样本聚为一组，并与其他样本遗传距离较大；（4）按产地分组，遗传差异的80.44%存在于居群内，8.29%来自于组内居群间，11.27%的遗传差异来自于组间。
