Recent declines in costs accelerated sequencing of many species with large genomes, including hexaploid wheat (Triticum aestivum L.). Although the draft sequence of bread wheat is known, it is still one of the major challenges to developlocus specific primers suitable to be used in marker assisted selection procedures, due to the high homology of the three genomes. In this study we describe an ...

ABSTRACT Fusarium head blight (FHB) caused by Fusarium graminearum is one of the most destructive diseases of durum (Triticum turgidum sp. durum) and common wheat (T. aestivum). Promising sources of FHB resistance have been identified among common (hexaploid) wheats, but the same is not true for durum (tetraploid) wheats. A previous study indicated that chromosome 7A from T. turgidum sp. dicocc...

Historical Although the wheat plant (Triticum) is nowhere found in the wild state, it has been cultivated for human food from the earliest times of which we have record. The origin is held to have been in south-west Asia, in Mesopotamia. When Abraham (about 2000 B.C.) was visited by three angels unawares, he commanded Sarah to ‘make ready quickly three measures of fine meal, knead it, and make ...

Fusarium head blight (FHB) is one of the most devastating diseases of wheat (Triticum aestivum L.), and the development of cultivars with FHB resistance is the most effective way to control the disease. Yumechikara is a Japanese hard red winter wheat cultivar that shows moderate resistance to FHB with superior bread-making quality. To identify quantitative trait loci (QTLs) for FHB resistance i...

Proper selection of endogenous reference genes and their real-time PCR assays is quite important in genetically modified organisms (GMOs) detection. To find a suitable endogenous reference gene and its real-time PCR assay for common wheat (Triticum aestivum L.) DNA content or copy number quantification, four previously reported wheat endogenous reference genes and their real-time PCR assays wer...

The influence of spherical nanoparticles (NPs) of nickel Ni° (70±0.3 nm in diameter) in the concentrations of 0.025, 0.05 and 0.1 M on the root part of 4-day-old seedlings of wheat Triticum vulgare wheat has been studied. After treating plants with nanoparticles, an increase was observed in the fluorescence of dichlorofluorescein and malondialdehyde (MDA), as well as strong haphazard DNA degrad...

110 Journal of Plant Registrations, Vol 2, No. 2, May 2008 ‘Alice’ (Reg. No. CV-1023, PI 644223) hard white winter wheat (Triticum aestivum L.) was developed by the South Dakota Agricultural Experiment Station and coreleased by the South Dakota and Nebraska Agricultural Experiment Stations in August 2006. In addition to researchers at South Dakota State University, researchers at the University...

Exposure of six wheat (Triticum aestivum L.) and one rye (Secale cereale L.) cultivar to 40% relative humidity for 24 hours induced the same degree of freezing tolerance in seedling epicotyls as did cold conditioning for 4 weeks at 2 degrees C.Frost hardiness varietal relationships were the same in desiccation-stressed and cold-hardened seedlings. Drought stress could, therefore, be used as a r...

Journal of Plant Registrations, Vol. 3, No. 1, January 2009 51 W heat streak mosaic virus (WSMV) is one of the most common, and devastating, diseases impacting wheat (Triticum aestivum L.) production in the western Great Plains of North America. Annual production losses of 5% have been estimated, although severe local WSMV infection can result in complete crop failure (French and Stenger, Regis...
