Synchrotron techniques have been used to investigate a range of processes in soils and plants. While these applications were initially addressing environmental issues related to pollution, recent years have seen increasing interest in using synchrotron approaches for agricultural research. This presentation will focus on new methodologies developed to address some major challenges related to...
Micronutrients copper (Cu) and iron (Fe) are essential for plant growth but can be toxic when over-accumulated in cells. Thus, plants tightly regulate their root uptake systems to prevent deficiency while avoiding toxicity. This includes balancing Cu/Fe accumulation via the Cu-Fe crosstalk and systemic shoot-to-root signaling through the phloem to report the shoots’ demand. However, only...
Seeds undergo a tightly regulated developmental program throughout their germination. Although mineral nutrients are crucial during all phases of a plant’s life cycle, little is known regarding their role in tissue differentiation. Herein, both synchrotron and benchtop-based X-ray fluorescence spectroscopy approaches revealed that manganese (Mn) and iron (Fe) exhibit particular ‘stripe-like’...
CARNAÚBA is an acronym for Coherent X-ray Nanoprobe Beamline, which is a nanofocused, multi-analytical and coherent X-ray imaging beamline of Sirius, the 4th generation synchrotron source of the Brazilian Synchrotron Light Laboratory. Its design is all-achromatic mirror-based optics, with a 4-bounce Si(111) crystal monochromator (4CM) that provides resolving power of E/E =10-4 in...
