为了明确河南省烟草疫霉群体的遗传多样性与遗传结构,利用RAPD分子标记对河南省的34个烟草疫霉菌株进行分析。结果表明,6条RAPD引物共扩增出30个条带,多态性条带比率为90%;Nei’s基因多样性指数为0.271 0,Shannon信息指数为0.402 8;菌株间的遗传相似系数在0.59~1.00,相似系数0.80水平下UPGMA聚类可将34个菌株划分为6个类群,类群Ⅰ包括26个菌株,为优势类群...
We used the random amplified polymorphic DNA-polymerase chain reaction (RAPD-PCR) technique to discriminate the major emerging poultry pathogen, Mycoplasma gallisepticum (MG), in broiler and chukar pa...
Asparagus (Asparagus officinalis L.) plants are dioecious. All-male cultivars are desired because of their higher yields. To increase the proportion of male individuals planted in the field and expedi...
Genetic variation of striped stem borer Chilo suppressalis populations in Guilan and Mazandaran provinces in Iran was studied in 2010 by means of RAPD markers. Collected 45 samples from 19 locations...
Quince (Cydonia oblonga Mill.) is a minor fruit crop, which is primarily used for marmalade, jam, sauce and as rootstocks for pears. Different cultivated and local quince genotypes are grown in almost...
n this study, 30, 15 and 1 strains of Pasteurella multocida and 9, 8 and 6 strains of Mannheimia haemolytica from cattle, sheep and goats isolated in Elazig province located in the East ...
Entomopathogenic and mycoparasitic fungi were characterised by RAPD technique, with special attention to evaluate the genetic stability of strains that are used as active ingredients in commercial bio...
Fifty-one grapevine cultivars registered in the Czech Republic were a subject of RAPD analysis. Nine grapevine varieties which were supposed to be genetically distant, were analysed by means of 120 Op...
Nine identification RAPD markers (Moravcová et al. 2003) were used to distinguish 24 clones and grapevine cultivars. No polymorphism was detected among all the tested clones of Chardonnay, Pinot gris ...
ABSTRACT GENETIC VARIABILITY IN HYDRASTIS CANADENSIS L. USING RAPD ANALYSIS FEBRUARY 2009 KERRY J. KELLEY, B.A. MOUNT HOLYOKE COLLEGE M.A. UNIVERSITY OF MASSACHUSETTS AMHERST Directed by: Professor Ly...
斜带石斑鱼(Epinephelus coioides)为中国南方重要的海水增养殖经济鱼类,但过度捕捞和人工养殖的快速扩张,导致了其自然资源衰退和遗传多样性降低。文章采用随机扩增多态DNA(RAPD)和线粒体细胞色素b(Cyt b)基因序列分析方法,对惠州、深圳和湛江3个斜带石斑鱼养殖群体进行了遗传多样性状况和遗传差异的研究。结果表明:1)相比较于线粒体Cyt b基因序列分析,RAPD技术在研究斜带...
This study was performed to characterize 35 L. monocytogenes isolates from animals, foods, environmental samples collected between 1997 and 2007 with no apparent epidemiological relations, and five re...
The 18 samples representing 18 populations of Strobilanthes cusia (Nees) O. Ktze in Fujian Province of China were analyzed with RAPD markers. Eleven primers were used, a total of 106 bands were scored...
In order to develop specific genetic markers and determine the genetic diversity of Bangladeshi native cattle (Pabna, Red Chittagong) and exotic breeds (Sahiwal), randomly amplified polymorphic DNA (R...
采用随机扩增多态DNA(random amplified polymorphic DNA,RAPD)技术检测广西沿海及其邻近海区拟穴青蟹(Scylla paramamosain)6个地理群体的遗传变异和遗传结构,8条10 bp寡核苷酸随机引物扩增99个个体,分析其中的44个位点,31个位点表现出多态性,在种水平的多态位点百分率为70.45%。POPGENE分析结果显示,6个群体的多态位点百分率为2...
