anthracnose caused by colletotrichum gloeosporioides s. l. is one of the most important diseases of citrus in northern iran. to study the genetic structure of c. gloeosporioides s. l. from citrusspp., infected samples were collected from three citrus cultivating regions of northern iran, during the summer of 2009. fifty one monoconidial isolates were used as the objective of rep- and box-pcr fi...

background: trichomonas vaginalis is protozoan parasite responsible for trichomoniasis and is more common in high-risk behavior group such as prostitute individuals. interest in trichomoni­asis is due to increase one's susceptibility to viruses such as herpes, human papillomavirus and hiv. the aim of this study was to find genotypic differences between the isolates. methods: forty isolates from...

background: fasciola hepatica and f. gigantica are the causative agents of fasciolosis in domestic animals and humans. based on the morphometric criteria, differential diagnosis between them is problematic. in addition, intermediate forms of fasciola have been found in iran, which makes the differentiation more difficult. the aim of the present study was to provide molecular evidence for the ex...

background: the present study was formulated in order to determine pol­ymorphism of dihydropteroate synthetase gene (dhps) of plasmodium vivax (p . vivax ) in hormozgan province, southern iran and mutations at codons 382, 383, 512, 553, and 585 associated with resistance of p. vivax to sulfadoxine. method : one-hundred eighteen isolates of p. vivax were prepared within 2007-2008 to determine di...

Chickpea (Cicer arietinum L.) is one of the most important legume crops in Iran. Wilt disease caused by Fusarium oxysporum f. sp. ciceri, is the most important soil-borne disease of chickpea in the world. This disease caused high losses in different regions during recent years. Simple sequence repeat (SSR) were used to estimate genetic diversity in 114 of F. oxysporum isolates from six counties...

Many researchers consider the use of different probes for hybridization assays as suitable for studying the genetic diversity of nitrogen fixing bacteria. In this study for asessing genetic diversity among Bradyrhizobium japonicum isolates, two different probes (sucA and topA) chosen from the chromosomal genome of Bradyrhizobium strain USDA 110 were designed, evaluated by DNAMAN software and im...

many researchers consider the use of different probes for hybridization assays as suitable for studying the genetic diversity of nitrogen fixing bacteria. in this study for asessing genetic diversity among bradyrhizobium japonicum isolates, two different probes (suca and topa) chosen from the chromosomal genome of bradyrhizobium strain usda 110 were designed, evaluated by dnaman software and im...

The main purpose of this study was to investigate the genetic diversity and population structure of Liza klunzingeri in two regions of the Persian Gulf. In this study, the amplified fragment length polymorphism (AFLP) was employed to analyze population genetic diversity between two populations (Ziyarat & Hendijan). Seven primer combinations (E-AAG/M-CTA, E-ACT/ M-CAA, E-ACT/ M-CTA, E-AAG/M-CTG,...
