A total of 204 isolates of Phytophthora infestans from Northern Ireland, almost all from commercial potato crops, were collected over 5 years (1998–2002). Phenotypic diversity was assessed using mating type and metalaxyl resistance; genotypic diversity was assessed using two allozyme loci (glucose-6-phosphate isomerase, Gpi, and peptidase, Pep ), mitochondrial DNA haplotype and the multilocus R...

Bali cattle is one of Indonesia's original livestock genetic resources. The 12S rRNA can be used as a marker diversity, and until now, there has been no report on cattle. study was aimed to analyze the gene mtDNA determine haplotype diversity phylogenetics in populations eastern region Indonesia. A total 95 blood samples consisted three different which were cattle, Ongole crossbred (PO) Madura ...

G6PD deficiency mutational profile and haplotype diversity using 6 RFLPs (FokI/PvuII/BspHI/PstI/BclI/NlaIII) and a (CTT)(n) microsatellite, were investigated in 70 G6PD-deficient Portuguese individuals. All but one G6PD A-(376G/202A) variants (44/45) have a single haplotype (+/+/-/+/-/+/195). G6PD Betica(376G/968C) alleles (n=10) have a single RFLP haplotype (+/-/-/+/-/+) and 4 different (CTT)(...

Genetic diversity of sea turtles (hawksbill turtle) was studied using sequencing of mitochondrial DNA (mtDNA, D-loop region). Thirty dead embryos were collected from the Kish and Qeshm Islands in the Persian Gulf. Analysis of sequence variation over 890 bp of the mtDNA control region revealed five haplotypes among 30 individuals. This is the first time that Iranian haplotypes have been recorded...

Echinococcus granulosus is the causative agent of cystic echinococcosis with medical and veterinary importance in China. Our main objective was to discuss the genotypes and genetic diversity of E. granulosus present in domestic animals and humans in western China. A total of 45 hydatid cyst samples were collected from sheep, humans, and a yak and subjected to an analysis of the sequences of mit...

To obtain a full understanding of the genetic diversity of the cytochrome oxidase III gene (COX-III) and its association with high altitude adaptation in Tibetan chickens, we sequenced COX-III in 12 chicken populations (155 Tibetan chickens and 145 other domestic chickens). We identified a total of 11 single nucleotide polymorphisms (SNPs) and 12 haplotypes (Ha1-Ha12). Low genetic diversity (ha...

Lontra provocax is an endemic species from Patagonia that has been categorized as "endangered" by the International Union for Conservation of Nature. In this study, noninvasive molecular methods were used to investigate the genetic diversity and haplotype distribution of L. provocax in Argentinean Patagonia. We analyzed 150 scat samples collected from 1995 to 2006 and obtained 13 sequences of c...

leaf blotch disease of barley, caused by rhynchosporium secalis is a major disease of barley in iran. its worldwide occurrence and economic importance in barley production has motivated studies on the population genetic structure of this pathogen. random amplified polymorphic dna (rapd) method was utilized to investigate the genetic diversity of populations of r. secalis isolated from barley le...

Mitochondria1 DNA (mtDNA) control region sequences were analyzed to evaluate the population genetic structure of Persian sturgeon (Acipenser persicus) in Caspian Sea. A total of 45 specimens were collected from the different locations of the Caspian Sea. MtDNA control region was amplified using PCR. Direct sequencing was performed according standard method. The results showed that 12 haplotypes...
