Orientia tsutsugamushi is the etiological agent of scrub typhus, an acute, mite-borne, febrile illness that occurs in the Asia-Pacific region. Historically, strain characterization used serological analysis and revealed dramatic antigenic diversity. Eyeing a recommendation of potential vaccine candidates for broad protection, we review geographic diversity and serological and DNA prevalences. D...

background endophytic fungi, which have been reported in numerous plant species, are important components of the forest community and contribute significantly to the diversity of natural ecosystems. objectives the current study aimed to evaluate and characterize, at the molecular level, the diversity and antimicrobial activities of endophytic fungi from medicinal plants in saudi arabia. materia...

Plants and insects comprise the most species-rich lineages of multicellular eukaryotes. Most insects are herbivores, and generally have specific adaptations for feeding on a very limited group of evolutionarily or biochemically related host plants in their natural habitats. Coevolutionary interactions (reciprocal natural selection) between plants and insects are hypothesized to be the crucible ...

grapes are among the world most planted horticultural crops. since the last century, attempts have been made to improve the quality of grapes in the world. meanwhile, the necessity of having knowledge about the history of progenies families led to the link between genealogy and breeding. considering some previous mislabeling, in order to find out the accuracy of the controlled crosses as well a...

background and objectives: molecular epidemiology tools are widely used in determining epidemiology of tuberculosis. spoligotyping is a molecular epidemiology method that is used for characterization and typing of mycobacterium tuberculosis complex strains. the method is based on polymorphism of the chromosomal dr locus consisting of identical 36-bp drs alternating with 35-41 unique spacers. th...

The genetic variability of the Brazilian physic nut (Jatropha curcas) germplasm bank (117 accessions) was assessed using a combination of phenotypic and molecular data. The joint dissimilarity matrix showed moderate correlation with the original matrices of phenotypic and molecular data. However, the correlation between the phenotypic dissimilarity matrix and the genotypic dissimilarity matrix ...

The molecular marker (SSR) has been used to investigate the markers associated with the agronomic traits including days to 50% flowering, tube ring time, days to maturity, plant height, the number of main stems per plant, the number of tubers per plant, dry matter content, main stem diameter, a single tuber weight, average single tuber weight, and the total yield in potato genotypes. Ten primer...

In this study, Dunaliella has been isolated in Jun. 2014 from Hoz-e Soltan and Aran-va-Bidgol salt Lakes (Iran). The isolates have been identified morphologically with the aid of simple light and invert microscope after isolation and purification on their specific medium (Moh202). By using molecular techniques such as polymerase chain reaction (PCR) and amplification of 18S rDNA gene primers, f...

Chamomile (Matricaria chamomilla), an important medicinal plant belonging to the Asteraceae family, has a wide distribution in Iran and other parts of the world. The medicinal and pharmacological effects of chamomile are mainly associated with its essential oil content and it is widely used in food, cosmetics and pharmaceutical industries. Despite its wide geographical distribution in Iran, lit...
