Objective: The aim of this study was to estimate genetic variability and phonetic relationships of 50 isolates of P. sojae from Iran. Methods: During 2005–2007, 142 isolates of Phytophthora sojae were collected from soil samples and diseased soybean plants from Lorestan, Mazandaran, Golestan and Ardabil provinces. Races of the isolates were determined. DNA of P. sojae...

The obligatory human pathogen, Mycobacterium tuberculosis, is the most important etiological factor of tuberculosis. Unfortunately, there is little information about genetic diversity of this pathogen. The main aim of this research was the estimation of genetic diversity of M. tuberculosis on the basis of various categories of DNA markers. The genome of 32 strains were scanned by DNA markers su...

Huntington's disease (HD) is a progressive, adult-onset neurodegenerative disease caused by a polyglutamine (polyQ) expansion in the N-terminal region of the protein huntingtin (HTT). There are no cures or disease-modifying therapies for HD. HTT has a highly conserved Akt phosphorylation site at serine 421, and prior work in HD models found that phosphorylation at S421 (S421-P) diminishes the t...

chamomile is a medicinal plant with high economic value. in this research, 20 chamomile ecotypes collected from different regions of iran were evaluated for genetic and chemical diversity. dna was extracted by ctab and polymerase chain reaction was performed using 13 rapd markers. essential oils extraction was performed by water distillation using clevenger system. components of the essential o...

Eggplant (Solanum melongena), a vegetable that is cultivated worldwide, is of considerable importance to agriculture in China. We analyzed the diversity of this plant using inter-simple sequence repeat (ISSR) and RAPD procedures to subdivide 143 Chinese-cultivated eggplants based on coefficient of parentage, genetic diversity index (GDI) and canonical discriminant analysis. ISSR markers were mo...

Mapping rust, anthracnose and angular leaf spot resistance genes in common bean using RAPD markers Molecular markers were used to study the organization of rust, anthracnose and angular leaf spot resistance genes in common bean (Phaseolus vulgaris) Ouro Negro cultivar. A segregant population of 154 recombinant inbred lines (RIL ́s) from the crossing between Ouro Negro and Rudá cultivars was inoc...

An F(1) mapping population of the septoria tritici blotch pathogen of wheat, Mycosphaerella graminicola, was generated by crossing the two Dutch field isolates IPO323 and IPO94269. AFLP and RAPD marker data sets were combined to produce a high-density genetic linkage map. The final map contained 223 AFLP and 57 RAPD markers, plus the biological traits mating type and avirulence, in 23 linkage g...
