Abstract:: ... Siderophores are natural metal chelating agents that strongly control the biogeochemical metal cycles such as Fe in the environment. This article describes a new methodology to detect and quantify at the micromolar concentration the spatial distribution at millimeter scale of siderophores within the root’s system. The “universal” CAS assay originally designed for bacterial siderophores detection a ...

Abstract:: ... A convenient and stable method for expressing crop seed growth is important both in experimental and simulation studies. The conventional approach has been to measure the seed growth rate (SGR) of individual seeds and multiply this by the number of seeds per unit ground area. An alternative to measurements of SGR has emerged from the observation that during seed growth, harvest index (HI) increase ...

Abstract:: ... The fate and availability of soil P in the central Great Plains may become less predictable with less tillage and more intensive crop rotations that produce more crop residue and litter than conventional-till (CT) wheat (Triticum aestivum L.)-fallow (W-F). We need to evaluate these new systems relative to new P distribution patterns that may be occurring. We determined P changes in a Weld silt loa ...

Abstract:: ... The combined long-term effects of tillage method, crop rotation, and N fertilizer rates on grain yield have not been studied in rainfed systems under Mediterranean climates. As part of a long-term experiment started in 1986, a field study was conducted between 1994 and 1998 to determine the effects of tillage (TILL), crop rotation (ROT), and N fertilization on wheat (Triticum aestivum L.) growth a ...

Abstract:: ... The magnitude of the response of stomatal conductance to a change in the concentration of carbon dioxide external to the leaf from 350 to 700 cm3 m-3 was found to be extremely variable from day to day in the field in Glycine max, Hordeum vulgare and Triticum aestivum. It was found that the leaf-to-air water vapour pressure difference (LAVPD) during the midday measurements of the stomatal response ...

Abstract:: ... The importance of the two chiral centers at C-3 and C-7 in the molecular structure of jasmonic acid in plant responses was investigated. We separated methyl jasmonate (MeJA) into (3R)- and (3S)-isomers with a fixed stereochemistry at C-3, but epimerization at C-7 is possible. The four isomers of the nonepimerizable analog 7-methyl MeJA were synthesized. These six esters and their corresponding aci ...

Abstract:: ... Thioredoxins (TRXs) and glutaredoxins (GRXs) are ubiquitous small redox proteins belonging to the thioredoxin (TRX) superfamily. They regulate several cellular functions via mediating a dithiolldisulphide exchange in target proteins. Thioredoxins have been classified into several subgroups based on their structural homologs. In an attempt to identify thioredoxin proteins which have not been charac ...

Abstract:: ... Mediterranean cropping systems in rainfed conditions are generally based on rotations with a very high frequency of winter wheat and, therefore, they are at risk of declining trends for yield and soil health in the long-term. In order to quantify this risk, a long-term experiment was set-up in 1971 in central Italy, which is still running at present (2016). This experiment is based on 13 rotations ...

However, it is difficult to disentangle the effects of intensive monoculture (e.g. pesticide use, mechanical ploughing and reduced protective cover), let alone evaluate how far the reduction of crop diversity affects biodiversity. It remains unclear to which extent the consequent decrease in food resources ...
