macrophomina phaseolina is a soilborne pathogen with a worldwide distribution and a host range of over 500 plant species. to study the genetic diversity and host specialization of this fungus in iran, plants with signs and symptoms of charcoal rot were collected from 12 provinces during years 2006 to 2008. following isolation and purification, 52 isolates from 24 host plants were identified thr...

The genetic diversity of 20 Iranian populations of Bunium persicum has been evaluated with random amplified polymorphic DNA (RAPD) and amplified fragment length polymorphism (AFLP) markers. Fresh leaves of seedlings from each population were used for genomic DNA extraction. Analysis of banding patterns of 15 RAPD primers and 17 AFLP primer combinations, revealed 192 (86%) and 228 (75%) polymorp...

Paecilomyces variotii is one of the most important causal agents of dieback disease in pistachio (Pistacia vera) gardens. The disease affects different parts of the tree, such as branch and trunk. Assessment of genetic structure in different populations of this species will lead to more useful management of pistachio dieback disease. In this study, genetic variation within samples of P. varioti...

different species of streptomyces are common in most types of soil. some certain species are plant pathogenic especially on potato. this study was conducted to evaluate genetic diversity among some local streptomyces spp. strains isolated from soil and infected tubers in potato farms in northwest of iran. repetitive dna elements (box, eric and rep) as genetic markers were used for diversity stu...

conclusions this is the first research in comparing two genetic marker systems in p. variotti. we were prompted to explore polymorphisms utility in p. variotti with a look at using germplasm screening mapping of genome and strain improvement programs. results both systems discriminated 20 isolates of p. variotii successfully but were different in the amount of detectable polymorphism. using clu...

Abstract Determination of genetic diversity level is important in clarifying genetic relationships, characterizing germplasm and the registration of new cultivars. In this study, genetic variation among 56 accessions (G1~G56) of Citrus including several undefined local or native genotypes and some known varieties in Jiroft, Kerman province, Iran was investigated using SSR markers. In total, 12 ...
