Sequence diversity of 39 dispersed gene loci was analyzed in 48 diverse individuals representative of the genus Pisum. The different genes show large variation in diversity parameters, suggesting widely differing levels of selection and a high overall diversity level for the species. The data set yields a genetic diversity tree whose deep branches, involving wild samples, are preserved in a tre...
Haloxylon salicornicum (Moq.) Bunge ex Boiss is a shrub that grows in large parts of the central regions of Iran. Due to the high adaptability of this species to the severe environmental conditions and its importance in the stabilization of sand dunes, Dust control and medicinal functions recognition of its genetic diversity and the selection of superior genotypes is very important. A set of ...
The large number and high diversity of genetic resource collections usually affect the accuracy of assessment and exploitation of the potential of these resources. The core collection provides the solution for the challenges of genetic resources manegement. This study aimed to develop the core collection of native barley germplasm of Iran. The germplasm collection of barley germplasm (Hordeum v...
Background and aim: Staphylococcus aureus can colonizes variety of body sites such as skin, coetaneous membrane and especially anterior nares. The coagulase gene (coa) typing is a technique in which the organism is typed based on the polymorphic region of the coa gene. The aim of the present study was to determine the coa based typing of S. aureus isolates from health care workers in two teach...
تنش دمای پایین یکی از مهم ترین عوامل محیطی است که عملکرد گیاهان را محدود می نماید. شبکه وسیعی از ژن های مختلف در تنظیم تحمل گیاه به این تنش نقش ایفا می نمایند. در این تحقیق، نخست 921 عدد از ژن های مذکور از تحقیقات و مقالات معتبر علمی استخراج گردید و سپس به منظور شناسایی ژن های مشابه با آنها در ژنوم کامل دو گیاه سیب (malus domestica)و انگور (vitis vinifera)، توالی آمینو اسیدی این ژن ها در گیاه م...
The evolutionary and adaptive potential of populations or species facing an emerging infectious disease depends on their genetic diversity in genes, such as the major histocompatibility complex (MHC). In birds, MHC class I deals predominantly with intracellular infections (e.g., viruses) and MHC class II with extracellular infections (e.g., bacteria). Therefore, patterns of MHC I and II diversi...
Abstract Backgraound: Entamoeba histolytica antigenic markers such as Serine-Rich E. histolytica protein (SREHP) have recently been used for vaccine preparation, genetic diversity studies of Entamoeba histolytica isolates and for differentiation between E. histolytica and E. dispar species. This study was carried out with the aim of expression of a recombinant Serine Rich E. histolytica prot...
Crop populations in smallholder farming systems are shaped by the interaction of biological, ecological, and social processes, occurring on different spatiotemporal scales. Understanding these dynamics is fundamental for the conservation of crop genetic resources. In this study, we investigated the processes involved in sorghum and pearl millet diversity dynamics on Mount Kenya. Surveys were co...
the lactic acid bacteria (lab) are an industrially important group of probiotic organisms that play an important role in human health by inhibiting harmful and pathogen bacteria growth, boosting immune function, and increasing resistance to infection. this study aimed to isolate, identify, and biologically characterize probiotic lab strains from iranian traditional dairy products. a total of 2...
How neuronal diversity emerges from complex patterns of gene expression remains poorly understood. Here we present an approach to understand electrophysiological diversity through gene expression by integrating pooled- and single-cell transcriptomics with intracellular electrophysiology. Using neuroinformatics methods, we compiled a brain-wide dataset of 34 neuron types with paired gene express...
