in order to study the genetic diversity among some male pistachio genotypes,16 male pistachio genotypes and 8 female pistachio cultivars were selected from iranian pistachio research institute (ipri). 12 rapd primers were used which totally produced 65 bands that among them 48 bands were polymorphic and 17 bands were monomorphic. cluster analysis based on similarity matrix and jaccard similarit...

study of genetic relationships is a prerequisite for plant breeding activities as well as for conservation of genetic resources. since the hybrid canola have more yield than inbred lines, determine the genetic diversity of this have particular importance. in the present study, genetic diversity among 36 genotype of brassica sp. were determined using inter simple sequence repeat (issr) markers. ...

a novel acrylic acid-functionalized fe3o4 magnetic nanoparticle with a core-shell structure was developed for utilization as a heterogeneous organosuperacid in chemical transformations. the structural, surface, and magnetic characteristics of the nanosized catalyst were investigated by various techniques such as transmission electron microscopy (tem), thermogravimetric analysis (tga), and ft-ir...

Species diversity protection will ensure the protection of natural processes and ecological values. Appropriate information on the condition and location of endanger species will facilitate the management and conservation of forest areas. The present study was conducted in Arasbaran forests for the purpose of evaluating two sampling methods including circular sampling (1000 m2 area) and the nea...

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...

The recent increased integration of evolutionary theory into conservation programs has greatly improved our ability to protect endangered species. A common application of such theory links population dynamics and indices of genetic diversity, usually estimated from neutrally evolving markers. However, some studies have suggested that highly polymorphic adaptive genes, such as the immune genes o...

biodiversity/biological diversity Species, genetic, and ecosystem diversity in an area, sometimes including associated abiotic components such as landscape features, drainage systems, and climate. diversity indices Measures that describe the different components of biodiversity, such as species richness (alpha diversity), beta and gamma diversity, endemicity, and higher taxon richness. ecosyste...

Grapevine (Vitis vinifera L.) is a clonally propagated major fruit crop. In grapevine, identification of genotypes with amplographical features is often based on mature plant characteristics that may be affected by environmental conditions. This approach lacks objectivity and reliability. Recently, molecular markers have proved to be supplementary techniques to analyze genetic diversity and exa...
