Aegilops tauschii, the wild relative of wheat, has stronger seed dormancy, a major component of preharvest sprouting resistance (PHSR), than bread wheat. A diploid Ae. tauschii accession (AUS18836) and a tetraploid (Triticum turgidum L. ssp. durum var. Altar84) wheat were used to construct a synthetic wheat (Syn37). The genetic architecture of PHS was(More)
Radiation use efficiency (RUE) of a crop is a function of several interacting physiological phenomena, each of which can be tackled independently from the point of view of genetic improvement. Although wheat breeding has not raised RUE substantially, theoretical calculations suggest room for improvement. Selection for higher rates of leaf photosynthesis at(More)
ABSTRACT Resistance to Barley yellow dwarf virus (BYDV) is not found in wheat but is available in a Thinopyrum intermedium translocation (Ti) carried on chromosome 7DL of bread wheat recombinant lines. We used one of those lines (TC14/2*Spear) to introgress the Ti into bread wheat cultivars and to determine the influence of wheat backgrounds, with and(More)
To improve the accuracy and precision of the assay of aluminum in brain tissue, we modified for application to brain samples from rats and humans the wet-digestion method of Trapp et al. (Biol Psychiatry 1978; 13:709-18), established the contribution of contamination, and examined the effect of precipitation of nonoxidizable fatty residues on the analysis.(More)
Deposition of aluminum in the body is responsible for the development of dialysis-related diseases in patients with renal dysfunction and may play a role in the development of certain neurodegenerative disorders. Although citric acid is known to be a strong enhancer of gastrointestinal absorption of aluminum, its effect on aluminum distribution and(More)
The binding of aluminium in rat serum was studied. Rats were loaded intraperitoneally with different doses of aluminium(III)chloride 4 times during one week, before being killed by cardiac puncture. One ml of serum was applied to a Sephacryl S-200 SF column and 70 fractions were collected. In the collected fractions, the distribution of aluminium was(More)
Aluminum (Al) has been observed to cause neurofilament protein accumulation in both experimental animals and cultured cells. Impairment of axonal transport is thought to be a mechanism of toxicity. Inhibition of the degradation of neurofilament proteins, however, resulting in accumulation of these proteins may be an alternative mechanism for Al toxicity. In(More)
The effects of citric acid and dinitrophenol on the mucosal uptake of aluminum (Al) and its appearance in the portal and systemic blood were investigated to establish the energy dependence of these processes. Therefore, the rat small intestine was perfused in situ with media containing 20 mmol Al/liter, with or without 5 mmol citric acid/liter, and with or(More)
