Tentative identification of phytochelatins, their derivatives, and Cd-phytochelatin complexes in Ocimum basilicum L. roots by Paper Spray Mass Spectrometry.

An unprecedented and direct PS-MS (paper spray ionization mass spectrometry) method was proposed for the detection of native peptides, that is, glutathiones (GSHs), homoglutathiones (hGSHs), and phytochelatins (PCs), in basil (Ocimum basilicum L.) roots before and after cadmium exposure. The roots were submitted to cold maceration followed by sonication with formic acid as the extractor solvent for sample preparation.

Ionomic responses of hydroponic-grown basil (Ocimum basilicum L.) to cadmium long-time exposure.

The ionomic response of basil leaves, stems, and roots to Cd2+ was evaluated in seedlings grown in a hydroponic system for 15 days. Ions were quantified by the inductively coupled plasma-mass spectrometry (ICP-MS). Cd accumulated mainly in roots, while Be, Li, Ca, Mg, and Sr in leaves, and K and Mn in stems.

Interactions between As and Se upon long exposure time and effects on nutrients translocation in golden flaxseed seedlings.

Se is a beneficial nutrient for some plant species, while As is considered a toxic element, even at low concentrations. This study investigated the interaction between As and Se on golden flaxseed (Linum usitatissimum L.) seedlings to better understand the extent of Se in the mitigation of As uptake and translocation.
