A PCR-based method was developed to distinguish between durum/common wheat and common wheat by leveraging slight differences of DNA sequence in Starch Synthase II (SS II) coded on wheat A, B and D genomes. A primer pair, SS II ex7-U/L, was designed to hybridize with a conserved DNA sequence region found in SS II-A, B and D genes. Another primer pair, SS II-D 1769U/1889L, was constructed to reco...

Drought is a major abiotic stress that is threatening the production and the survival of many crops such as cereals. The response of three Aegilops crassa accessions (C1, C2 and C3) that inhabit areas with different rates of rainfall and durum wheat to controlled drought (with soil moisture of 50% field capacity) was tested in terms of changes in: relative water content, chlorophyll content, ch...

Characterization of germplasm by DNA-markers provides a tool for precise germplasm identification and a quantitative assessment of genetic diversity. The genetic structure of the durum wheat germplasm grown in the Mediterranean basin varies largely from traditional landraces and cultivars characterized by a high versatility, to the modern varieties characterized by high yield potential, wide ad...

Pyrenophoratritici-repentis is the causal agent of tan spot. According to their ability to produce necrosis and/or chlorosis on a set of four differential bread wheats, the isolates of this fungus are currently grouped into eight races. When durum wheat genotypes were added to the differential set, a new virulence type was identified in Algeria. The isolates showing this virulence pattern are u...

Tunisia is considered as a diversification centre of durum wheat (Triticum durum Desf.) and barely (Hordeum vulgare). It is characterised by large genetic diversity; however, several genotypes are in the process of disappearance. The safeguard and rehabilitatation of this genetic inheritance requires genetic characterisation, evaluation and in-situ and ex-situ conservation. In this context, a l...

of North America. A total of about 1.5 million ha of durum is planted annually in the USA, with about 80% The accumulation of Cd in edible crops is undesirable because of concentrated in northern North Dakota. In some locapotential risks to human health. Agronomic efforts to lower Cd in foods will be more effective if we understand the extent and causes of spatial tions, durum wheat grain may e...

Understanding the genetic bases of economically important traits is fundamentally important in enhancing genetic gains in durum wheat. In this study, a durum panel of 208 lines (comprised of elite materials and exotics from the International Maize and Wheat Improvement Center gene bank) were subjected to genome wide association study (GWAS) using 6,211 DArTseq single nucleotide polymorphisms (S...

in the present study, we have reported the biological synthesis of silver nanoparticles (agnps) using aqueous leaf extract prepared by hot percolation treatment of wheat varities (pbw343, triticum durum and aegilops tauschii )for the reduction of silver ions to silver nanoparticles. bioreduction of ag+ to ag0 was observed when aqueous extract augmented with silver nitrate (agno3) was incubated ...

      In order to study the effects of post-anthesis heat stress and nitrogen levels on grain yield and yield components of wheat genotypes, two separate field experiments were conducted in delayed and optimum sowing dates under Ahvaz conditions (2006-2007). The Ahvaz site located in south west of Iran (32°20' N, 40°20' E) with subtropical climate condition. The experiment site had a moderate w...

Wild emmer wheat, Triticum dicoccoides, is the progenitor of modern tetraploid and hexaploid cultivated wheats. Our objective was to map domestication-related quantitative trait loci (QTL) in T. dicoccoides. The studied traits include brittle rachis, heading date, plant height, grain size, yield, and yield components. Our mapping population was derived from a cross between T. dicoccoides and Tr...
