Gravitropism of oat (Avena sativa L.) and wheat (Triticum aestivum L.) coleoptiles was investigated in relation to the displacement angle or to the initially set stimulation angle (SA). We measured curvature rates at the early phase of curvature, before it was affected by the drop in SA resulting from the curvature response itself. The plot of the rates against the sines of initial SAs revealed...
Two compost formulations based on oat straw (Avena sativa) and brachiaria (Brachiaria sp.) were tested for the cultivation of three Agaricus bisporus strains (ABI-07/06, ABI-05/03, and PB-1). The experimental design was a 2 × 3 factorial scheme (composts × strains) with 6 treatments and 8 repetitions (boxes containing 12 kg of compost). The chemical characterization of the compost (humidity, or...
Feedbacks between plants and soil biota are increasingly identified as key determinants of species abundance patterns within plant communities. However, our understanding of how plant-soil feedbacks (PSFs) may contribute to invasions is limited by our understanding of how feedbacks may shift in the light of other ecological processes. Here we assess how the strength of PSFs may shift as soil mi...
This paper concerns a new class of antiauxins, substances in themselves devoid of activity in the Avena coleoptile section growth test but capable of antagonizing the growth promoting effects of both native and synthetic auxins. These compounds, to which antiauxin activity has not previously been ascribed, are the diortho substituted phenoxyacetic acids. To establish rigorously that a growth in...
Nutritional changes of common oat (Avena sativa L.) and naked oat (Avena nuda L.) during germination
The phytochrome holoprotein of plants requires a covalently bound linear tetrapyrrole (bilin) prosthetic group for its photoreceptor function. Here we show that synthetic phytochrome apoprotein prepared by transcription and translation of an Avena phytochrome cDNA construct combines in vitro with phycocyanobilin, an analog of the natural chromophore, to produce a photoactive holoprotein. These ...
Recognizing a need in cultivated hexaploid oat (Avena sativa L.) for a reliable set of reference SNPs, we have developed a 6K BeadChip design containing 257 Infinium I and 5,486 Infinium II Page 1 of 32 The Plant Genome Accepted paper, posted 06/19/2014. doi:10.3835/plantgenome2014.03.0010
Fructan was precipitated from a water and ethanol extract of oat (Avena sativa L.) and barley (Hordeum vulgare L.). The degree of polymerization and response on a differential refractometer, based on peak area and height, was compared to fructan collected from a lead-based HPLC column and to commercially available inulin. Statistically significant differences are discussed.
