بررسی تنوع ژنتیکی ژنوتیپ‏های بومی پیاز ایرانی در مقایسه با انواع خارجی چکیده: برنامه های اصلاحی گیاهان بر اساس تنوع و انتخاب صفات برتر کمی و کیفی صورت می گیرد. لذا، ارزیابی تنوع ژنتیکی، اولین مرحله در برنامه های اصلاحی است. در این راستا، استفاده از روش های جدید مطالعه‏ی تنوع ژنتیکی ضروری به نظر می رسد. در این بررسی تعیین تنوع ژنتیکی سیزده ژنوتیپ پیاز ایرانی در مقایسه با دو ژنوتیپ خارجی با است...

A novel Dasypyrum species, Dasypyrum breviaristatum, serves as a valuable source of useful genes for wheat improvement. The development and characterization of new wheat-D. breviaristatum introgression lines is important to determine the novel gene(s) on specific chromosome(s). We first used multi-color fluorescence in situ hybridization (FISH) to identify the individual D. breviaristatum V(b) ...

Most species of the genus Lophopyrum Löve (Agropyron Geartn.) grow in saline environments and are more tolerant of saline stress than the species of the related genus Triticum L. A 56-chromosome amphiploid from the cross Triticum aestivum cv. Chinese Spring x Lophopyrum elongatum exceeded Chinese Spring in salt tolerance, measured as plant dry-matter production and seed yield in solution cultur...

Introduction & Objective: Undoubtedly reproduction as a means of human survival and recurrent spontaneous abortion being the most prevalent complication of pregnancy with a three percent outbreak and an influential problem on human life have always been the subject of interest among researchers. Different factors are involved in recurrent spontaneous abortion among which immunological disord...

the main purpose of this study was to investigate any relationship between high school efl teachers metaphorical understandings of their role in class and their self-efficacy beliefs. teachers metaphors were elicited through two different prompts: one picturing what they believed a language teacher should be like in class, and the other demonstrating what they are actually like in class; such...

Objective Objective: Toxoplasma gondii is one of the major causes of abortion in pregnant women. Most cases of abortion occur in the acute phase of infection and early pregnancy. In this study, the seroprevalence of anti-Toxoplasma gondii IgM and IgG antibodies was investigated in women with first spontaneous abortion. Also to determine the acute and chronic infections, all IgM and IgG positive...

To transfer multiple desirable alien genes into common wheat, we previously reported a new trigeneric hybrid synthesized by crossing a wheat - Thinopyrum intermedium partial amphiploid with wheat - Psathyrostachys huashanica amphiploid. Here, the meiotic behavior, chromosome constitution, and stripe rust resistance of F5 derivatives from the wheat - Th. intermedium - P. huashanica trigeneric hy...

We briefly review the properties of the N = 2 U(N) gauge model with/without matters. On the vacua, N = 2 supersymmetry and the gauge symmetry are spontaneously broken to N = 1 and a product gauge group, respectively. The masses of the supermultiplets appearing on the N = 1 vacua are given. We also discuss the relation to the matrix model.
