Assessing the Germplasm of Laminaria （Phaeophyceae） with Random Amplified Polymorphic DNA （RAPD） Method     

赫英俊  邹俞萍  王晓东  郑治国  张大明  段德麟 《中国海洋湖沼学报》2003,21(2):141-148

Eighteen gametophytes including L.japonica ,L.ochotensis and L.longissima,were verified with random amplified polymorphic DNA (RAPD) technique.Eighteen ten-base primers were chosen from 100 primers selected for final amplification test.Among the total of 205 bands amplified ,181(88.3%) were polymorphic ,The genetic distance among different strains ranged from 0.072 to 0.391,The dendrogram constructed by unweighted pair -group method with arithmetic(UPGMA) method showed that the female and male gamtophytes of the same cell lines could be grouped in pairs respectively,It indicated that RAPD analysis could be used not only to distin-gusih different strains of Laminariz ,but also to distinguish male and female gametophyte within the same cell lines,There is ambiguous systematic relationship if judged mereely by the present data It seems that the use of RAPD marker is limited to elucidstion of the phylogenetic relationship among the species of Laminaria.  相似文献   

Microsatellite Variation in the Oyster Crassostreaplicatula Along the Coast of China     

YU Hong  LI Qi YU Ruihai 《中国海洋大学学报(英文版)》2008,7(4)

Genetic diversity and differentiation of the oyster Crassostreaplicatula populations from China's coast were studied basedon seven microsatellite loci.All loci showed high polymorphism for all five C.plicatula populations,with an average number of alleleper locus of 19.3-27.9 and an average expected heterozygosity of 0.889-0.952.Significant departures from Hardy-Weinberg equilib-rium and deficits of heterozygotes were observed over most populations at each locus,which were fully explained by null alleles.Microsatellite analysis revealed significant subdivision in the C.plicatula populations.According to the neighbor-joining tree con-structed on the basis of the D,A distance,the five populations fell into three regional groups,showing a relatively homogeneous geneticstructure in geographically close populations.Assignation tests correctly assigned high percentages of individuals to their originalpopulations and groups,and also confirmed the existence of genetic differentiation among C.plicatula populations.The results ob-tained in this study will facilitate the formulation of appropriate fisheries management programs,stock identification and conservationof biodiversity for the species.  相似文献
