Light-grown 7-day-old wheat seedlings (Triticum aestivum, var. Maris Dove) showed an increase of 200% in plastids per cell between 1.7 and 4.5 centimeters from the leaf base. This increase was the result of divisions of young chloroplasts at various stages of development, and was well separated in distance, and therefore in time from the region of cell division in the basal meristem.

Abstract: Increased crop density and use of herbicides are two important components of integrated weed management program in wheat but no much information is available on combined effects of these two treatments. A field experiment was conducted to determine the interaction effect of increasing seed rates and weed management treatments on monocot and dicot weeds, grain and straw yield and uptak...

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...
