سد سازبن ، دریکی ازسرشاخه های حوزه کرخه دراستان ایلام ،شرق سرآبله ودرحدود 3 کیلومتر بعدازتلاقی دو رودخانه سیمره و چرداول در داخل تنگ سازبن احداث خواهد شد. جهت تعیین ارزش پوشش گیاهی واقع درمخزن، ابتدا بابازدید ازمنطقه پوشش گیاهی براساس روش های متداول دردنیا با نمونه برداری سیستماتیک -تصادفی شناسایی ،سپس با توجه به قوانین نرخ گذاری درکشور ارزش جنگل ها ومراتع برآورد و درنهایت مشخص شد باتشکیل دریا...
in order to investigating theeffects of crop rotation and applying of herbicides on weed distribution in irrigated wheat fields of kermanshah province, this study was performed during 2011-2012. multivariate analysis (rda) revealed the significant relationship between composition and species frequency and exerted management techniques. the first and second features of rda indicated 57%, 74.9...
Gene duplication is a major evolutionary driving force for establishing new gene functions. However, very little is known about the involvement of the structural divergence of recent duplicated genes in local adaptation. We evaluated the nucleotide variation of recent duplicated pair copies of the hsp17 locus for small heat shock proteins, namely, the older copy hsp17a and the younger copy hsp1...
Wild barley [Hordeum vulgare ssp. spontaneum (C. Koch) Thell.] is a part of the primary gene pool with valuable sources of beneficial genes for barley improvement. This study attempted to develop a core subset of 269 accessions representing 16 countries from the Plant Gene Resources of Canada (PGRC) collection of 3,782 accessions, and to characterize them using barley simple sequence repeat (SS...
Using Roche/454 technology, we sequenced the chloroplast genomes of 12 Triticeae species, including bread wheat, barley and rye, as well as the diploid progenitors and relatives of bread wheat Triticum urartu, Aegilops speltoides and Ae. tauschii. Two wild tetraploid taxa, Ae. cylindrica and Ae. geniculata, were also included. Additionally, we incorporated wild Einkorn wheat Triticum boeoticum ...
The National Bioresource Project-WHEAT (NBRPWHEAT), launched by the Japanese government in 2002, aims to maintain and distribute seed stocks and DNA clones of “Wheat”. The second-term NBRPWHEAT started in 2007. Additionally to its primary roles in handling seed stocks and DNA clones, the second-term NBRP-WHEAT features the collection and characterization of DNA markers, which will make the seed...
Genetically well-characterized mapping populations are a key tool for rapid and precise localization of quantitative trait loci (QTL) and subsequent identification of the underlying genes. In this study, a set of 73 introgression lines (S42ILs) originating from a cross between the spring barley cultivar Scarlett (Hordeum vulgare ssp. vulgare) and the wild barley accession ISR42-8 (H. v. ssp. sp...
