Summary Elevated nicotianamine synthesis in roots of A rabidopsis halleri has been established as a zinc (Zn) hyperaccumulation factor. The main objective this study was to elucidate the mechanism nicotianamine‐dependent root‐to‐shoot translocation metals. Metal tolerance and accumulation wild‐type ( WT ) Ah NAS 2 ‐ RNA interference i) plants were analysed. Xylem exudates subjected speciation analysis metabolite profiling. Suppression root had no effect on Zn cadmium (Cd) but rendered nickel...
Summary Siderophores are organic chelators produced by microorganisms to fulfil their iron requirements. Siderophore‐promoted dissolution of iron‐bearing minerals has been clearly documented for some siderophores, but few studies have addressed metabolizing siderophore‐producing bacteria. We investigated acquisition from clays fluorescent P seudomonads, bacteria that ubiquitous in the environment. focused on interactions between smectite and seudomonas aeruginosa , a bacterium producing two...
This study characterizes sunflower response to the levels of Cd encountered in moderately Cd-polluted soils. Two cultivars differing their ability sequestrate roots were exposed low concentrations (0.5 nM or 100 nM) hydroponics and sampled after 18 days (258 degree-days) when ten leaves fully expanded. Plant growth, uptake partitioning among organs monitored along with ionomic (ICP-MS) metabolic (1H-NMR) composition xylem sap. Sunflower tolerance differed between two cultivars. The cultivar...
Environmental Context.In some agricultural areas, soils are contaminated by trace elements. This contamination of cultivated may constitute a serious problem for human health through the accumulation metals in edible parts crops. In order to assess risk associated with metal soil, we need develop simple tools like Diffusive Gradients Thin Films (DGT) predicting crop accumulation. The present study focuses on an site fallout from industrial dust and reveals that DGT could be predictive tool...
Aerated compost teas (ACTs) are rich in soluble humic substances (SHS) that have high affinity for metals, notably Cu. Using a batch experiment, we measured the extent to which two ACTs altered Cu dynamics vineyard topsoils one day and 21 days after their addition. Soils were extracted with 0.01 M KCl, total concentration, free ion fraction size distribution of ligands extraction solution assess impact ACT on mobility Diffusive gradient thin film (DGT) measurements carried out effect...
Post-anthesis phosphorus (P) uptake and the remobilization of previously acquired P are principal sources grain nutrition in wheat. However, how reaches grains its partitioning at whole plant level remain poorly understood. Here, temporal dynamics newly durum wheat organs allocation to were examined using pulse-chase 32P-labeling experiments 5 14 days after anthesis. Durum plants grown hydroponically under high low supplies. Each labeling experiment lasted for 24 h. Plants harvested 24, 48,...
