the dry bubble disease, caused by lecanicillium fungicola, is an important fungal disease of white button mushroom in iranian mushroom production farms. twenty-three isolates of the pathogen collected in iran and identified as l. fungicola var. fungicola, were compared for genetic polymorphism, diversity in growth rate and virulence. ten universal rice primers (urp) were used to evaluate the ge...

AIM To compare the genomic variability and the multiple colonization of Helicobacter pylori (H. pylori) in patients with chronic gastritis from two Colombian populations with contrast in the risk of developing gastric cancer (GC): Túquerres-Nariño (High risk) and Tumaco-Nariño (Low risk). METHODS Four hundred and nine patients from both genders with dyspeptic symptoms were studied. Seventy-tw...

genotypes can be easily identified (Huang et al., 1997; Hittalmani et al., 2000). A PCR-based Pi-ta gene marker Incorporation of resistance genes into existing rice (Oryza sativa is useful in marker-assisted selection breeding since it L.) cultivars is a powerful strategy and is commonly applied in breeding rice resistance to blast disease [caused by Pyricularia grisea Sacc. is the part of resi...

Estimation of genetic diversity is an important factor in germplasm conservation and characterization. In rice breeding programs, genetic diversity information on specific regions of genome can be very useful for the application of marker assisted selection (MAS) and for gene mapping. A total of 152 rice lines were considered for breeding programs using microsatellites (SSR) technique. The tota...

The Persian sturgeon, Acipenser persicus (Borodin, 1897), is an economically important species, which mainly inhabits the Caspian Sea. However, little is known about its population genetic structure. In this study, variation in nucleotide sequences of the mitochondrial DNA (mtDNA) control region of wild stock Persian sturgeon was determined to assess the genetic diversity among different natura...

We focus on the development of microsatellite loci isolated from two scleractinian coral species (Montastraea cavernosa and Porites astreoides). To analyze the genetic structure of scleractinian coral populations, it is essential to identify a genetic marker that can evaluate individual or population-level differences (Shearer and Coffroth 2004). Optimal PCR conditions are essential when develo...
