The capability to generate densely sampled single nucleotide polymorphism (SNP) data is essential in diverse subdisciplines of biology, including crop breeding, pathology, forensics, forestry, ecology, evolution and conservation. However, the wet-laboratory expertise bioinformatics training required conduct genome-scale variant discovery remain limiting factors for investigators with limited re...

The aim of genetically comparing different populations of the same species of natural enemies is to identify the strain that is most adapted to the environment where it will be released. In the present study, Inter-Simple Sequence Repeat-Polymerase Chain Reaction (ISSR-PCR) was utilized to estimate the population genetic structure of Gonatocerus ashmeadi (Girault) (Hymenoptera: Mymaridae), the ...

Improvement of high yielding, disease resistant silkworm strains became imminent to increase production of silk, which is a major revenue earner for sericulturists. Since environment interacts with phenotype, conventional breeding did not result in commendable yield improvement in synthetic strains of silkworm, Bombyx mori. Identification of DNA markers associated with different economically im...

The genus Salicornia (Amaranthaceae) was established by Linnaeus. Commonly known as ‘glassworts’, the species of are articulated succulent herbs with cortical palisade, opposite decussate scale-leaves, thyrsoid cymes, flowers packed in cauline depressions and diaspore composed l-seeded utricle. Therefore, due to importance plant species, we performed a combination morphological molecular data a...

Analysis of the extent and distribution of genetic diversity in crop plants is essential for optimizing sampling and breeding strategies. Several methods were identified for the existence of diversity in maize for the aim of perfect selection based on great diversity among maize genotypes. In this study, Inter-simple sequence repeat (ISSR) markers were used to assess genetic diversity in a sele...

The genetic diversity and population structure of Salvia lachnostachys Benth were assessed. Inter Simple Sequence Repeat (ISSR) molecular markers were used to investigate the restricted distribution of S. lachnostachys in Parana State, Brazil. Leaves of 73 individuals representing three populations were collected. DNA was extracted and submitted to PCR-ISSR amplification with nine tested primer...

انجیر به عنوان یک محصول مهم، در چند دهه اخیر به دلیل بروز تنش­های زنده و غیر زنده دچار فرسایش ژنتیکی شده است. هدف از این تحقیق تعیین تنوع ژنتیکی گونه­های خودروی سرده Ficus در ایران با استفاده از نشانگر ISSR می­باشد. جهت انجام این تحقیق، تعداد 23 نمونه جمعیتی متعلق به  گونه­های این جنس از سراسر کشور جمع آوری و DNA ژنومی آنها از برگ استخراج گردید. از میان 18 آغازگر ISSR مورد آزمایش، شش جفت آغازگر...

The genetic structure of five Fennoscandian populations of the threatened wood-decay fungus Fomitopsis rosea (Basidiomycota) was investigated using codominant PCR-RFLP, allele specific amplification (ASA) markers, inter simple sequence repeat (ISSR) markers and mating studies. Sequence analyses of a subset of single spore isolates revealed sequence variation in four target sequences; internal t...

Cambui (Myrciaria tenella O. Berg) is a native species from Brazil, which belongs to the family Myrtaceae. Molecular characterization is one of the most used tools for the study of the biotechnological potential of species because the diversity level between individuals can be inferred. Analysis of genetic diversity is fundamental to the direction of the strategies necessary to form and maintai...

Necrophagous fly is the most common insect evidence collected during a death investigation. We analyzed the DNA polymorphism among the five forensically important fly species, namely, Lucilia sericata, Aldrichina grahami, Chrysomya megacephala, Parasarcophaga crassipalpis and Musca domestica using inter simple sequence repeat (ISSR) method. Nine ISSR primers selected from 18 primers could ampli...
