Chemical mutagenesis in Triticum aestivum

Mutation Research, 1964
Abstract Treatment of common wheat with ethyl methanesulfonate had effects strikingly different from those characteristically obtained in irradiation experiments. Of 558 M1 plants, 175 had recognizable mutant sectors, almost all of which were necrotic or chlorophyll-defective stripes in leaves.

Pollen callus culture in Triticum aestivum

Theoretical and Applied Genetics, 1982
Pollen shed between 4-8 d from anthers of Triticum aestivum cultured in liquid medium gave rise to calluses. Tillers were harvested at the mid-to late-unicellular pollen stages and chilled for 8 d at 4-5 °C before the anthers were dissected out. Pollen cultures gave about 6 times as many calluses on a per anther basis as anthers cultured on solid ...

Allelopathy in wheat (Triticum aestivum)

Annals of Applied Biology, 2001
SummaryWheat (Triticum aestivum) allelopathy has potential for the management of weeds, pests and diseases. Both wheat residue allelopathy and wheat seedling allelopathy can be exploited for managing weeds, including resistant biotypes. Wheat varieties differ in allelopathic potential against weeds, indicating that selection of allelopathic varieties ...

The influence of salicylic acid (S??) on heat- and salt resistance of winter wheat (Triticum aestivum) plantlets has been studied. Treatment of bleached-out plantlets raised their surviving the after damage-heating and the influence of salt (NaCl) stress.

Leaf wax of Triticum aestivum

Phytochemistry, 1973
Abstract Leaf waxes from spring wheat varieties Selkirk and Manitou contain hydrocarbons (6%, 10%), long chain esters (14%, 13%), free acids (5%, 8%), free alcohols (19%, 21%), β-diketone (16%, 20%), hydroxy β-diketones (8%, 10%), unidentified gum (29%, 16.5%) and minor amounts of diol diesters, glycerides and aldehydes.

Genetics of yellow berry in wheat (Triticum aestivum)

Theoretical and Applied Genetics, 1986
The inheritance of yellow berry, a grain disorder in durum and bread wheats, was studied in six intervarietal crosses in bread wheat. The trait was found to be controlled by either two or three dominant genes. Monosomic analysis using 'Chinese Spring' monosomic series showed the presence of two major dominant genes on chromosomes 1A and 7A, and four ...

Using a method of induced fluorescence of chlorophyll the influence of virus infection on the slate of wheat photosynthetic apparatus has been researched, in particular, on the photosystem 2. The connection between induced chlorophyll fluorescence parameters and the concentration of virus in the cell is described.

Identification and verification of microRNA in wheat (Triticum aestivum)

Journal of Plant Research, 2008
MicroRNAs (miRNAs) are small, endogenous RNAs that regulate gene expression in both plants and animals. A large number of miRNAs has been identified from various animals and model plant species such as Arabidopsis thaliana and rice (Oryza sativa); however, characteristics of wheat (Triticum aestivum) miRNAs are poorly understood.
