Three fractions of rye-grass (Lolium perenne) pollen extract have been isolated by preparative isoelectric focusing (i.e.f.) and characterized in terms of physicochemical and immunochemical properties. The purified components were designated 'R7' and 'R14' on the basis of their positions in relation to other rye-grass pollen extract components on SDS/polyacrylamide-gel electrophoresis and their...
We report on a whole-genome draft sequence of rye (Secale cereale L.). Rye is a diploid Triticeae species closely related to wheat and barley, and an important crop for food and feed in Central and Eastern Europe. Through whole-genome shotgun sequencing of the 7.9-Gbp genome of the winter rye inbred line Lo7 we obtained a de novo assembly represented by 1.29 million scaffolds covering a total l...
DNA extraction from plant tissues often causes most problems. For example, unsuccessful removal secondary metabolites during extraction, such as phenolic compounds in aromatic and medicinal plants, cause to some mistakes in result of molecular experiments by using of the extracted DNA. Achillea wilhelmsii is a medicinal plant belong to Asteraceae family and native to Iran, there is little infor...
We attempted to develop a PCR-based marker that detects various segments of rye chromosome incorporated into wheat. We designed three sets of PCR primers based on the nucleotide sequence data of a rye repetitive sequence previously reported. One of the primer sets amplified a clear ca. 1.4 kb fragment in a rye cultivar but not in any form of wheat, diploid, tetraploid or hexaploid. We used this...
genetic typing methods of t. gondii strains have been extensively perfected in recent years. from a technical point of view, many tools usable for genetic studied on single-copy loci have been used: rflp, pcr-rflp, sequencing, rapd-pcr and isoenzyme analysis. we described the cloning and sequence analysis of the gene which encodes the major surface antigen (sag1 or p30) of t. gondii. sag1 is th...
Abstract Food fraud is becoming a prominent topic in the food industry. Thus, valid methods for detecting potential adulterations are necessary to identify instances of cereal products, significant component human diet. In this work, primer–probe systems real-time PCR and droplet digital (ddPCR) detection these species: bread wheat (together with spelt), durum wheat, rye barley ddPCR were estab...
Centromeres typically contain tandem repeat sequences, but centromere function does not necessarily depend on these sequences. We identified functional centromeres with significant quantitative changes in the centromeric retrotransposons of wheat (CRW) contents in wheat aneuploids (Triticum aestivum) and the offspring of wheat wide hybrids. The CRW signals were strongly reduced or essentially l...
background chronic hepatitis b virus (hbv) infection is a multifactorial disease that can result in serious clinical complications. host genetic background especially the genes that encode immunologic factors like inf-γ and its receptor (ifn-γ r) are critical in the pathogenesis of infection. materials and methods genomic dna from peripheral blood samples of 200 chronically hbv infected patient...
سقط جنین گوسفندان از دیر باز یکی از بزرگترین مشکلات صنعت گوسفند داری نه تنها درکشور ما بلکه در اغلب کشورهای پرورش دهنده گوسفند بشمار می رود وهمه ساله باعث تحمیل خسارات سنگین اقتصادی بردامداران منطقه می گردد. کمپیلوباکتریوزکه در گذشته به ویبریوز معروف بوده، بعدازبروسلوز و لپتوسپیروز مهمترین عامل سقط جنین گوسفندان می باشد. زیرگونه های کمپیلوباکتر و بویژه کمپیلوباکترژژونای و فتوس بیشترین سقط جنین ...
this study investigated the genetic diversity of morchella species using randomly amplified polymorphic dna markers. morchella species are an important group of edible mushrooms belonging to the family helveliaceae with medicinal and economical significance. in this study we have developed an efficient method of genomic dna isolation which was amplified by eight rapd primers to test the polymor...
