Micro-PIXE analysis of biological tissue in frozen hydrated state
Primož Vavpetič, Primož Pelicon
Doktorska disertacija
Oznake: micro-PIXE;frozen hydrated specimen;focused ion beam;ion source;ion accelerator;biology;elemental analysis;elemental mapping;
Since mechanical damage, morphological changes and chemical oxidation during drying of biological samples still represent a major obstacle to keep the sample situation as in-vivo, technology of frozen hydrated tissue is expanding to research with nuclear microprobes. Slices of biological tissue afte ...

On the distribution and evaluation of Na, Mg and Cl in leaves of selected halophytes
Paula Pongrac, Katarina Vogel-Mikuš, Marjana Regvar, Mitja Kaligarič, Primož Vavpetič, Mitja Kelemen, Nataša Grlj, Primož Pelicon
Izvirni znanstveni članek
Oznake: light elements;micro-PIXE;salinity;salt tolerance;
Diverse physiological, biochemical and morphological adaptations enable plantsto survive in extreme saline environments where osmotic and ionic stresses limit growth and development. Halophytes are salt-tolerant plants that can withstand extraordinarily high levels of Na and Cl in their leaves. The ...

Arabidopsis halleri shows hyperbioindicator behaviour for Pb and leaf Pb accumulation spatially separated from Zn
Stephan Höreth, Paula Pongrac, Marta Debeljak, Katarina Vogel-Mikuš, Matic Pečovnik, Primož Vavpetič, Primož Pelicon, Iztok Arčon
Izvirni znanstveni članek
Oznake: Arabidopsis thaliana;elementalimaging;food webs;metal contamination;metal distribution;metal speciation;metallo-phyte;
Lead (Pb) ranks among the most problematic environmental pollutants. Background contamination of soils is nearly ubiquitous, yet plant Pb accumulation is barely understood. In a survey covering 165 European populations of the metallophyte Arabidopsis halleri, several field samples had indicated Pb h ...

Exploring the potential of cold plasma treatment followed by zinc-priming for biofortification of buckwheat sprouts
Pia Starič, Lucija Remic, Katarina Vogel-Mikuš, Ita Junkar, Primož Vavpetič, Mitja Kelemen, Paula Pongrac
Izvirni znanstveni članek
Oznake: Fagopyrum esculentum;common buckwheat;non-thermal plasma;zinc distribution;grain tissues;
Increasing the concentration of an element in edible produce (i.e., biofortification) can mitigate the element deficiency in humans. Sprouts are small but popular part of healthy diets providing vitamins and essential elements throughout the year. Element composition of sprouts can easily be amended ...

Temporal and spatial patterns of zinc and iron accumulation during barley (Hordeum vulgare L.) grain development
Amelie Detterbeck, Paula Pongrac, Daniel Persson, Katarina Vogel-Mikuš, Mitja Kelemen, Primož Vavpetič, Primož Pelicon, Iztok Arčon, Søren Husted, Jan Kofod Schjoerring, Stephan Clemens
Izvirni znanstveni članek
Oznake: barley (Hordeum vulgare L.);biofortification;grain development;grain loading;LA-ICP-MS;μ-PIXE;
Breeding and engineering of biofortified crops will benefit from a better understanding of bottlenecks controlling micronutrient loading within the seeds. However, few studies have addressed the changes in micronutrient concentrations, localization, and speciation occurring over time. Therefore, w ...

Tissue-specific calcium and magnesium allocation to explain differences in bulk concentration in leaves of one-year-old seedlings of two olive (Olea europaea L.) cultivars
Paula Pongrac, Mitja Kelemen, Katarina Vogel-Mikuš, Primož Vavpetič, Primož Pelicon, Paula Žurga, Nikolina Vidović, Marija Polić Pasković, Smiljana Goreta Ban, Igor Lukič, Igor Pasković

Olive tree (Olea europaea L.) leaves have recently been recognised as a valuable source in cosmetic and pharmaceutical industry as well as in preparation of health-supporting beverages. Little is known about the element composition of olive leaves and almost nothing about tissue-specific allocation ...
