گلابی از جنس pyrus، عضوی از زیرخانواده pomoideae و خانواده rosaceae است که بعد از سیب و انگور مهمترین میوه منطقه معتدله به شمار می آید. ایران با نزدیکی به مراکز تنوع گلابی و نیز دارا بودن بیش از ده گونه از جنس pyrus به عنوان یکی از مهم ترین منابع ژنتیکی گلابی در دنیا شناخته شده است. از طرف دیگر، کشور ایران با سطح کشتی معادل 17000 هکتار و با عملکرد 114706 کیلو گرم در هکتار یکی از مراکز تولید گلا...

Salinity is an important limiting factor in the production of more plants, including rice. Due to the limited amount of cultivated area, identification of tolerant genotypes to environmental stresses and especially salinity is very important. The aim of this study was to investigate the genetic diversity among 114 recombinant lines derived from the intersection of local Tarom × Khazar cultivars...

five subspecies of the persian jird, meriones persicus, were reported from iran. these subspecies were described based on morphological characters and coat colors of few specimens. the question of the validity of these subspecies and their geographic distribution is raised. in this study, we combined genetic markers (cox1, cytb and irbp genes), morphometric (external and skull measurments), mor...

Understanding genetic structure and status of genetic variation of Fasciola hepatica isolates from different hosts, has important implications on epidemiology and effective control of fasciolosis. Random amplified polymorphic DNA (RAPD-PCR) was used to study the genetic variation of F. hepatica in sheep and cattle. DNA was extracted from adult helminthes removed from livers of each infected ani...

in general, both common illnesses and rare diseases can develop in people and their relatives in families. therefore, taking family history is an effective screening tool to detect such diseases and patients should be aware of its importance in families’ health with updating information in regular visiting. for more information on identifying the genetic pattern of diseases, in this article, we...

The aim of the present study was the genetic analysis of the Dniester population of sterlet Acipenser ruthenus and comparison of it to five other sterlet populations, in order to develop a population recovery plan. The genetic analysis of six sterlet populations from Eurasian rivers (Dniester, Dnieper, Danube, Volga, Kama and Ob) was carried out using microsatellite DNA markers. The genetic var...

many agriculturally important traits are complex, affected by many genes and the environment. quantitative trait loci (qtl) mapping is a key tool for studying the genetic structure of complex traits in plants. in the present study qtls associated with yield and agronomical traits such as leaf number, leaf length, leaf width, plant height, stem and head diameter were identified by using 70 recom...
