Stripe rust (yellow rust), caused by Puccinia striiformis f. sp. tritici is one of the most damaging diseases of wheat in Pakistan. Lack of durable resistance in local wheat varieties is the main reason for stripe rust epidemic which could limit yields. The use of genetically resistant wheat varieties is the most economic way of controlling the disease. Evaluation of 135 advance wheat lines for...

A study was conducted to investigate the relationship between the presence of localized bacterial infection and lameness in broiler fowl (Gallus gallus domesticus). Isolation of bacteria from the proximal femur, proximal tibia, and tibiotarsus from broilers with lameness revealed a probable association between lameness and the presence of Staphlylococcus aureus. Other potential pathogens, inclu...

The present study investigated and identified genetic diversity between native White chicken lines two commercial Broiler (Rose) Layer (Isa Brown) breeds using RAPD markers a sequencing technique. All primers applied produced 151 scorable bands with percentage polymorphic loci of 54.93 % within populations, as per the results marker. maximum amplified fragment by primer OPC-11 was 22 fewest OPA...

The usefulness of random amplified polymorphic DNA (RAPD) was examined as a potential tool to differentiate cryptic mosquito species. It proved to be a quick, effective means of finding genetic markers to separate two laboratory populations of morphologically indistinguishable African malaria vectors, Anopheles gambiae and An. arabiensis. In an initial screening of fifty-seven RAPD primers, 377...

Over the last two decades, DNA fingerprinting have been increasingly used to characterize germplasm of different organisms including crop plants, which was otherwise difficult with morphological and or isozyme markers because of paucity of genetic information at phenotypic level. In the present study, two hybrid samples of sorghum (Sorghum bicolor L.) received from Federal Seed Certification an...

Background: Sainfoin (Onobrychis viciifolia) is a forage crop that yields high in arid and calcareous soils cultivated large areas. There aren’t many genetic diversity studies on the varieties of cultured sainfoin. This study was conducted to determine degree relationship between 23 landraces one registered variety. Methods: To take samples from populations, seeds were sown field 2014. Samples ...

The genotypes of 63 strains (11 reference strains and 52 strains from hospitalized patients) of the haploid yeast Candida glabrata were determined from 33 putative gene enzymatic loci. This enabled the characterization of 26 different multilocus genotypes. Genetic differentiation was found between distant hospitals (located in Montpellier and Paris, France) but not for other parameters (anatomi...

ABSTRACT Visible and nonvisible quiescent infections of immature and mature fruit are an integral component of the disease cycle of brown rot of sweet cherry in California. Detection of these infections is critical for developing efficient and efficacious fungicide management programs. The previously published DNA amplification primers mfs3 and NS5 for the identification of Monilinia fructicola...

one of the most important and elusive diseases of grapevine is esca disease. esca is a complex disease that comprises a combination of symptoms caused by various fungi including growth retardation, decrease in productivity and decline of the plant and usually affecting adult plants (8 to 10 years and older). the purpose of this research was to study the genetic variations of fungal agents assoc...

A differential pattern in the RAPD profile of Eucalyptus F1 natural hybrids FRI-4 (E. terticornis x E. camaldulensis), FRI-5 (E. camaldulensis X E. tereticornis) and controlled reciprocal crosses FRI-14 (E. torelliana X E. citriodora) along with their parental combinations was assessed through Polymerase Chain Reaction using commercially available primers. After electrophoresis of PCR product t...
