A detailed RFLP map was constructed of the distal end of the short arm of chromosome 1D of Aegilops tauschii, the diploid D-genome donor species of hexaploid wheat. Ae. tauschii was used to overcome some of the limitations commonly associated with molecular studies of wheat such as low levels of DNA polymorphism. Detection of multiple loci by most RFLP probes suggests that gene duplication even...
Construction of high-resolution genetic maps is important for genetic and genomic research, as well as for molecular breeding. Single nucleotide polymorphisms (SNPs) are the predominant class of genetic variation and can be used as molecular markers. Aegilops tauschii, the D-genome donor of common wheat, is considered a valuable genetic resource for wheat improvement. Our previous study implied...
The current limitations in genome sequencing technology require the construction of physical maps for high-quality draft sequences of large plant genomes, such as that of Aegilops tauschii, the wheat D-genome progenitor. To construct a physical map of the Ae. tauschii genome, we fingerprinted 461,706 bacterial artificial chromosome clones, assembled contigs, designed a 10K Ae. tauschii Infinium...
Sequence tagged site (STS) markers have been developed recently to identify resistance genes in wheat. A number of wild relatives have been used to transfer resistance genes into wheat cultivars. Accessions of wild species of Triticeae: Aegilops longissima (4), Ae. speltoides (6), Ae. tauschii (8), Ae. umbellulata (3), Ae. ventricosa (3), Triticum spelta (2), T. timopheevi (3), T. boeoticum (4)...
The elimination of DNA sequences following allopolyploidization is a well-known phenomenon. Yet, nothing is known about the biological significance, the mechanism, or the precise developmental timing of this event. In this study, we have observed reproducible elimination of an Aegilops tauschii allele in the genome of the second generation (S2) of a newly synthesized allohexaploid derived from ...
hedging is a multi-purpose rhetorical strategy which is usually used in scientific arguments to secure ratification of claims, reduce the risk of negation, avoid conflict, manage disagreement and leave room for the audience to assess presented information. hedges are frequently used in research articles to mitigate the findings of research endeavors. the present research aims to investigate the...
در این پژوهش به منظور شناسایی زیرواحدهای سبک گلوتنین (lmw-gs) از ژنوم d، 110 نمونه از گونه های گیاهی گندم نان،aegilops crassa ، ae. cylindrica و ae. tauschii. ارزیابی شد. در مجموع با توجه به نتایج آنالیز ژل های sds-page چهار آلل شناسایی شد. آلل a با فراوانی 45 درصد دارای بیشترین فراوانی و پس از آن آلل های b، c و d به ترتیب دارای فراوانی های 1/38 ، 8/11 و 1/9 درصد بودند. در گونة ae. crassa، آلل ...
this exploratory study aimed to investigate a possible relationship between learners’ beliefs about language learning and one of their personality traits; that is,locus of control (loc). both variables, beliefs and locus of control, are assumed to influence the language learning process. the internal control index (ici) and the beliefs about language learning inventory (balli) were administered...
this research was conducted to examine the effect of a concurrent training on rest level of leptin of plasma and some hormonal factors in non-athlete subjects. the research population included non-athlete men who didn’t participate in any organized sport activities. 30 men were chosen voluntarily among the above-mentioned population and were divided into 2 groups: experimental (15 subjects) an...
Towards the end of World War II, McFadden & Sears (1946) published a lengthy and classic paper on the origin of hexaploid or bread wheat. In the appendix to this paper they acknowledged that Kihara (1944) had also independently identified Aegilops tauschii (syn. Ae. squarrosa, Tritcum tauschii) as the D-genome donor of bread wheat. Since then, there have been many studies on the taxonomy, biolo...
