Due to genetic erosion over evolution events, the genetic diversity of domesticated safflower species for drought tolerance is limited. Wild species has been considered as useful genetic resources for improvement of abiotic stress tolerance. In this study, a cultivated species (C. tinctorius) was crossed by two wild species (C. palaestinus and C. oxyacanthus) and the genotypes were purified unt...
The genus Bartonella includes numerous species with varied host associations, including several that infect humans. Development of a molecular diagnostic method capable of detecting the diverse repertoire of Bartonella species while maintaining genus specificity has been a challenge. We developed a novel real-time PCR assay targeting a 301-bp region of the ssrA gene of Bartonella and demonstrat...
Microsatellite DNA markers isolated from wild species khinjuk (Pistacia khinjuk Stocks.) were used to evaluate the genetic diversity available in Iranian pistachio cultivars. Out of the 27 SSR primers tested initially, 25 could amplify the DNA in different pistachio cultivars, of which 19 primer pairs produced clear bands. Based on the amplification profiles of the genotypes by the remaining pr...
The wild-relative gene pools of wheat are a rich source of genetic variation for wheat improvement.Karyotypes of eight genotypes of Triticum monococcum subsp. aegilopoides and eight genotypes of Aegilops cylindrica,which grown wild next to each other in different regions in the west of Iran were studied. Root tips were treated in α-bromonaphthalene solution, fixed in chromic acid-formaldehyde f...
rapd markers were employed to assess the genetic diversity of 34 iranian wild edible asparagus (a. officinalis) genotypes as well as cv. mary washington and a. persicus. in total, 80 rapd primers were employed for pcr reactions, among which, 18 revealed reasonable polymorphism. the 18 primers produced 175 bands, of which, 160 were polymorphic (91.4% polymorphism). cluster analysis of the genoty...
Extended Abstract Introduction and Objective: Wild relatives of wheat are one of the most important genetic resources for use in wheat breeding programs. Therefore, identifying wheat wild relatives and Awareness of the diversity in them, also protecting these species is undeniably effective in expanding the richness of the gene pool and the genetic base of new cultivars and can be a good tool ...

چکیده: کنه های خانواده tenuipalpidae گیاهخوار و دارای انتشار جهانی هستند. این گروه از کنه ها به انواع درختان میوه، گیاهان و درختچه های زینتی و درختان جنگلی حمله نموده و علاوه بر تغذیه از شیره گیاهی و تخریب کلروفیل برگ در انتقال بیماریهای ویروسی به گیاهان نقش دارند. لذا شناسایی و مطالعه آنها حائز اهمیت است. در این پژوهش که طی سالهای 90-1389 انجام شد ضمن بررسی فونستیک کنه های تارتن دروغین استان ...
background: the intracellular protozoan parasites of the genus haemoproteus occur in different avian hosts all over the world. various genus of blood sucking insects’ families such as hippoboscidae and ceratopogonidae could transmit haemoproteus in avian hosts. there are very limited number of studies on wild infected birds with blood parasites in iran, so the aim of this study was to determine...
در این پژوهش تاکسونومی و تنوع گونه ای زنبورهای پارازیتویید گروه pimpliformes (hymenoptera: ichneumonidae) در شمال مرکزی ایران (استان های البرز، قزوین، گیلان و مازندران) طی سال های 1389-1390 مورد بررسی قرار گرفت. نمونه ها با استفاده از تله مالیز و تور حشره گیری جمع آوری شدند. در هر استان چهار محل با اختلاف ارتفاع حدود 500 متر و با شرایط زیستگاهی متفاوت انتخاب و در هر محل دو تله مالیز با فاصله 50...
