The amino acid sequences of phytochrome from Avena sativa, Oryza sativa, Curcurbita pepo, Pisum sativum and Arabidopsis thaliana have been analyzed with a variety of computer programs, with a view to identifying areas of the protein which contribute to the properties of this photoreceptor. A region at the C-terminus has been shown to be amphiphilic, and by analogy with surface-seeking peptides,...

Using horizontal and vertical axis clinostats and sand-grown oat seedlings (Avena sativa), it was found that horizontal clinostat rotation at 2 rpm increased respiration and inorganic and organic phosphorus content of seedlings. Increased coleoptile geotropism and root growth are attributed to rotational nullification of the directional component of the gravitational stimulus. These growth modi...

Objective(s): Nowadays, nanoparticles bio production, considering their performance in medicine and biological science, is increasing. Green synthesis of metal nanoparticles using organisms has emerged as a nontoxic and ecofriendly method for synthesis of metal nanoparticles The objectives of this study were the production of silver nanoparticles using Avena sativa L. ...

Short straw is a desired trait in oat germplasm (Avena sativa L.). Marker-assisted selection, a key tool for achieving this objective, is limited by the presence and number of available markers. Here, we have attempted to develop markers sufficiently linked to a gene specifying short straw so that marker-assisted selection could be applied. Bulked-segregant analysis was used to identify anonymo...

Two trials were conducted to evaluate the effect of different cereals in piglet diets on the jejunal mucosa and the ileal and cecal microbiota during the first postweaning days. In Trial 1, 48 newly weaned pigs (7.95 kg BW; 26 d of age) were individually housed and distributed among 3 experimental diets containing white rice (Oryza sativa), naked oats (Avena sativa), or barley (Hordeum vulgare)...

Chiasma counting has been regarded as the most straightforward method of scoring the total number of crossing-over events in the genome. In organisms in which genetic analysis is difficult or impossible to perform, it is a good estimator of the level of genetic recombination. In this paper we evaluated the chiasma frequency and distribution at diakinesis of twelve Brazilian oat varieties (Avena...

The role of extracellular fl-1,3-glucanases and chitinases was investigated in oat leaves after infection with different rust fungi . The oat leaves (Avena sativa L .) were inoculated with the compatible rust Puccinia coronata f. sp . avenae and the two nonpathogens Puccinia recondita f. sp . tritici and Puccinia graminis f. sp. tritici . No alterations in enzyme activities were found in the co...

In a randomized, placebo-controlled double-blind study, neurophysiological methods were used to determine the effects of Neurexan on patients’ psychophysiological con dition. The administration of Neurexan was found to help them to cope better with acute stress situations. The homeopathic combination medication Neurexan consists of the components passionflower (Passiflora incarnata), oats (Aven...
