take-all disease of wheat (gaeumannomyces graminis var. tritici) (ggt) is one of the most destructive root diseases in the world. it has not been introduced resistant genotype against this disease. in this study, 416 genotype of bread wheat, received from different location of iran and other countries, were evaluated to take-all (t-41 isolate) in greenhouse conditions. root dry weight, shoot dr...

In these investigations, the yield stability of 14 winter bread wheat genotypes were analyzed. The experimental part trial was performed at three locations (Kragujevac, Kruševac and Sombor) during 2013/2014. AMMI analysis variance for grain showed that all sources variation (genotype, environment, their interaction) had a significant effect on expression this complex trait. total experiment, la...

To investigate the role of Peroxidase and its physiological significance under Karnal Bunt (KB) were determined in resistant (HD-29) and susceptible genotype (WH-542) of wheat during different developmental stages. The enzymes were expressed constitutively in both the susceptible and resistant genotype. In gel assay and differential expression analysis of POD was significantly higher (p >0.05) ...

ABSTRACT Strains of Pseudomonas fluorescens producing the antibiotic 2,4-diacetylphloroglucinol (2,4-DAPG) are biocontrol agents which play a key role in the suppressiveness of some soils against soilborne pathogens. We evaluated the effect of the host plant genotype on rhizosphere colonization by both indigenous and introduced 2,4-DAPG-producing P. fluorescens. First, population densities of i...

Water deficit and increasing salinization reduce productivity of wheat, the leading crop for human diet. While the complete genome sequence of this crop has not been deciphered, a BAC library screening allowed the isolation of TdERF1, the first ethylene response factor gene from durum wheat. This gene is putatively involved in mediating salt stress tolerance and its characterization provides cl...

Background: Avian infectious bronchitis (IB), with avianinfectious bronchitis virus (IBV) as the causing agent, is a ubiquitous endemicdisease of the chicken with devastating effects on its industry. A viralmembrane surface protein called S  notonly induces neutralizing antibodies but also plays an important role in virusbinding and entry to host cells. Technically, S1 protein gene sequencing a...

The breeding material comprising 17 Iraqi wheat cultivars belongs to three different types, i.e., a) salinity-tolerant (Dajla, Furat, 1H, 2H, 2N, 3H, 3N, and 7H), b) drought-tolerant (Sham-6 Orok), c) local (Iraq, Iba99, Iba95, Abu Ghraib-3, Adnanin, Tamoze, Alrashid) underwent qualitative characteristics genomic analysis studies in 2021-2022, at the Biotechnology Research Center, Al-Nahrain Un...

Six commercial U.K. cultivars of winter wheat selected to represent different abilities to partition nitrogen into grain protein were grown in replicated field trials at five different sites over three seasons. The proportion of LMW glutenin subunits decreased and the proportion of gliadins increased during grain development and in response to N application. Differences were observed between th...
