Molecular diversity and metal accumulation of different Thlaspi praecox populations from Slovenia

Nuclear ribosomal sequences and Cd, Zn, Pb and Fe accumulation of different populations of hyperaccumulating species Thlaspi praecox Wulfen (Noccaea) were studied to reveal their relationships to other representatives of the genus and especially to the well known hyperaccumulator T. caerulescens; comparisons of their accumulating properties were also made.

A cellular study of teosinte Zea mays subsp. parviglumis (Poaceae) caryopsis development showing several processes conserved in maize

Teosinte is the wild progenitor of modern maize. The study showed that many cellular features that were previously attributed to domestication are already developed in teosinte. The only and most important difference between maize and teosinte is the distribution of endoreduplication, where cell number remains constant but nuclear DNA is replicated. Additional knowledge of this process could substantially improve our most important crop.

Complexation of cadmium in seeds and vegetative tissues of the cadmium hyperaccumulator Thlaspi praecox as studied by X-ray absorption spectroscopy

High amounts of Cd were measured in seeds without drastically affecting seed viability. In intact seeds and isolated embryos, almost two thirds of the Cd ligands were thiol groups (Cd­S­C­) while in roots and shoots up to 80% of the Cd ligands were oxygen ligands that are provided by the cell walls and by organic acids stored in vacuoles.

Flavonoid, tannin and hypericin concentrations in the leaves of St. John-s wort (Hypericum perforatum L.) are affected by UV-B radiation levels

St. John’s wort, grown under different levels of UV­B radiation, was analysed for its concentrations of flavonoids, tannins and hypericin. A high level of UV­B radiation increased leaf concentrations of flavonoids and of tannins. The concentration of hypericin in leaves exposed to enhanced UV­B radiation was lower than that of leaves exposed to reduced UV­B radiation.

Fungal community structure under goat willows (Salix caprea L.) growing at metal polluted site

Communities of endophytic fungi on the roots of goat willows (Salix caprea) growing in soil with different degrees of heavy metal pollution, were analysed using molecular tools. Additionally, leaf accumulated metals and photosynthetic pigments were analysed for evaluation of the fitness of goat willows growing at the polluted site.
