“…However, due to the poor separation efficiency of classical SEC columns, this chromatographic technique has been considered unable to provide speciation data and used solely for the estimation of the molecular weight of the species present [15]. The recent introduction of SEC materials, having the solvent stability and mechanical strength which allow their use in Ultra-High-Performance Liquid Chromatography (UPLC) mode, provided significant improvements in separation efficiency and 3-fourfold shortening of the analysis time [16,17]. In a given study, the species were separated within 15 min producing sharp peaks (2 peaks for B, Ba, Pb, and Sr; 1 peak for the rest of compounds).…”

Metal ions contribute to the wine browning (as reaction catalysts), turbidity (in complexes), and astringency (due to interaction with tannins). Being aware that bioavailability and metabolism of metal ions in the human body are strictly related with their concentration and the form they occur it is important to monitor not only the total content of metals but also their speciation. Thus, we can obtain more information about their potential toxicity to human health. Present research shows the application of fast size exclusion chromatography (Fast-SEC) coupled to ICP-MS for the evaluation of the distribution of elements in different sized complexes in Polish wine. The study was focused on the selected ten elements (Al, B, Ba, Cu, Fe, Mn, Ni, Pb, Sr, Zn). Additional information of this work was the evaluation of the metal complex stability over time. Based on the obtained results, it can be seen that metal complexes present in the studied wine samples are stable even 10 months after the wine bottle opening. Graphical abstract

“…Peak widths and peak shapes are repeatable ~ 3% RSD. Moreover, in HILIC gradient elution is commonly used which results in shifting ionization conditions in ICP-MS potentially affecting the dataset acquired (species more or less readily ionized) [16].…”

“…The speciation of As, Ag, Cu, Pb and Zn in four natural plants growing in a mining area in Peru has been studied. 128 Analysis were performed on the water extractable fraction (25 mmol L −1 NH 4 Ac) by using SEC and HILIC separation modes combined with ICP-MS and ES-Orbitrap-MS detection. Information of metal accumulation and translocation from root to aerial parts was achieved by acid digestion followed by ICP-MS measurements.…”

“…Phytosiderophores were also detected in exudates of grapevine (Marastoni et al 2020) and in the metal hyper-tolerant species Nicotiana thyrsiflora and Puya sp. (Kińska et al 2022). It appears from these observations that the mechanisms for Fe uptake are not as strictly separated by phylogenetic borders as previously suggested.…”

In concert with oxygen, soil alkalinity strongly restricts the availability of iron, an essential nutrient with a multitude of functions in living organisms. In addition to its role in mitochondrial energy metabolism and as a cofactor for enzymes, in plants iron also plays key roles in photosynthesis and is required for chlorophyll biosynthesis. The ability to thrive in calcareous soils, referred to as calcicole behaviour, is the readout of an amalgam of traits of which efficient foraging of iron is a decisive factor. Recently, the well-established concept of two distinct iron uptake strategies, phylogenetically separating grasses from other land plants, was expanded by the discovery of auxiliary mechanisms that extend the range of edaphic conditions to which a species can adapt. Secretion of a tailor-made cocktail of iron-mobilising metabolites into the rhizosphere, the composition of which is responsive to a suite of edaphic and internal cues, allows survival in calcareous soils through a competitive iron acquisition strategy, which includes intricate interactions with the consortium of associated microorganisms in, on, and around the roots. This versatile, reciprocal plant-microbiome interplay affects iron mobilisation directly, but also collaterally by impacting growth, fitness, and health of the host. Here, we review the mechanisms and the multifaceted regulation of iron acquisition in plants, taking into consideration the specific constraints associated with the uptake of iron from alkaline soils. Knowledge on how plants extract iron from such soils sets the stage for a better understanding of essential ecological processes and for combatting iron malnutrition in humans.
