Development of Schistosoma mansoni in the intermediate host Biomphalaria glabrata is influenced by a number of parasite and snail genes. Understanding the genetics involved in this complex host/ parasite relationship may lead to an often discussed approach of introducing resistant B. glabrata into the field as a means of biological control for the parasite. For the snail, juvenile susceptibilit...
Powdery mildew, caused by Blumeria graminis f. sp. tritici, is one of the most important wheat diseases in the world. In this study, a single dominant powdery mildew resistance gene MlIW172 was identified in the IW172 wild emmer accession and mapped to the distal region of chromosome arm 7AL (bin7AL-16-0.86-0.90) via molecular marker analysis. MlIW172 was closely linked with the RFLP probe Xpsr...
Scientific information on the A genome species of Gossypium is limited due to their decline as crop species and low levels of marker polymorphism. As the A subgenome of the allotetraploid species of Gossypium is contributed by A genome progenitors, studies on the A genome will help us understand the evolution of polyploids. We compared DNA marker order along the chromosomes of A, D and At genom...
In this study, Substitution at codon Ser315 of katG gene, a reliable marker for isoniazid (INH) resistance was analyzed and compared by three molecular methods such as DNA sequencing, polymerase chain reaction restriction fragment length polymorphism (PCR-RFLP) and PCR-single strand conformation polymorphism (PCR-SSCP) in 105 phenotypically resistant isolates obtained from various parts of Ind...
A 593 bp EcoRI-Bgll fragment encompassing bp 1012 to 1604 of the human insulin receptor cDNA (1). Polymorphism: EcoRI detects a two allele polymorphism with bands at 10.3 and 13.5 kb (Fig. 1. Lanes 1—4 shows three homozygotes and one heterozygote). Segregation: Segregation of alleles in tumors with 19p+ marker chromosomes (2) (Fig. 1). Lane 5 shows tumor DNA with duplicated 19p+ marker chromoso...
The primary screwworm fly Cochliomyia hominivorax (Coquerel) (Diptera: Calliphoridae) is one of the most important insect pests of livestock in neotropical regions, whereas Cochliomyia macellaria (Fabricius) (Diptera: Calliphoridae), the secondary screwworm, is of medical and sanitary importance because of its role in the dissemination of pathogens. These two species share morphological similar...
In previous studies we reported the identification of several AFLP, RAPD and RFLP molecular markers linked to apospory in Paspalum notatum. The objective of this work was to sequence these markers, obtain their flanking regions by chromosome walking and perform an in silico mapping analysis in rice and maize. The methylation status of two apospory-related sequences was also assessed using methy...
Protein and DNA polymorphismswere surveyed among seven accessions of wild fenugreek (Trigonellafoenum-graecum L.) to estimate their genetic diversity and relationships. Samples were obtained from diverse ecogeographical areas in Saudi Arabia and Yemen. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) analysis of seed storage protein showed genetic variations among fenugreek ...
