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...
Rice (Oryza sativa) and wheat (Triticum aestivum) are the most important starch crops in world agriculture. While both germinate with an anatomically similar coleoptile, this tissue defines the early anoxia tolerance of rice and the anoxia intolerance of wheat seedlings. We combined protein and metabolite profiling analysis to compare the differences in response to anoxia between the rice and w...
Electromagnetic field (EMF) and its effect on crop plant growth their quality parameters is increasingly gaining the interest of researchers in agronomic science. However, exact mechanism EMF action cells still unclear. Among completely unexplored relationship between effects seed size. Thus, was analyzed winter wheat seeds categorized into two size groups, small big. The study focused germinat...
We studied the temporal and spatial pattern of lipid transfer protein (LTP) gene expression, as well as the localization of this protein, in maize. Using an LTP gene, we observed an accumulation of LTP mRNA in embryos and endosperms during seed maturation. LTP gene expression was also investigated in young seedlings. After germination, the leve1 of LTP mRNA in the coleoptile increased, with a m...
About 10% of plant genomes are devoted to cell wall biogenesis. Our goal is to establish methodologies that identify and classify cell wall phenotypes of mutants on a genome-wide scale. Toward this goal, we have used a model system, the elongating maize (Zea mays) coleoptile system, in which cell wall changes are well characterized, to develop a paradigm for classification of a comprehensive ra...
The glyoxalase system plays an important role in various physiological processes plants when they are subjected to different types of stress, whether physical, chemical or biological. Aspergillus flavus is aflatoxin-producing fungus that contaminates dry grains, leading a gradual deterioration the grains and significant reduction their nutritional value. objective present study was evaluate act...
