“…In turn, metal sequestration may take place in the vacuole, dictiosomal vesicles, or the endoplasmic reticulum [ 33 , 34 ]. From an organismic point of view, ions can be withdrawn into aging leaves and trichomes or drawn outside by secretary glands, which has been observed in Arabidopsis thaliana and A. halleri [ 35 ], Alyssum montanum [ 36 ], and Biscutella laevigata [ 37 ].…”

“…In phytoextraction, which constitutes the most popular method of phytoremediation relying on the total removal of contaminants from the environment, hyperaccumulating plants may work the best due to their ability (about 100–1000-fold higher than in other plants) regarding effective uptake and translocation of metallic elements [ 45 ]. Many studies have demonstrated the phytoextraction potential of metallophytes from various genera, such as Alyssum murale [ 46 ], Arabidopsis halleri [ 35 ], Biscutella laevigata [ 37 ], and Stackhousia tryonii among others [ 47 ]. Nowadays, phytoextraction achieves two goals at once.…”

Environmental changes are inevitable with time, but their intensification and diversification, occurring in the last several decades due to the combination of both natural and human-made causes, are really a matter of great apprehension. As a consequence, plants are exposed to a variety of abiotic stressors that contribute to their morpho-physiological, biochemical, and molecular alterations, which affects plant growth and development as well as the quality and productivity of crops. Thus, novel strategies are still being developed to meet the challenges of the modern world related to climate changes and natural ecosystem degradation. Innovative methods that have recently received special attention include eco-friendly, easily available, inexpensive, and, very often, plant-based methods. However, such approaches require better cognition and understanding of plant adaptations and acclimation mechanisms in response to adverse conditions. In this succinct review, we have highlighted defense mechanisms against external stimuli (mainly exposure to elevated levels of metal elements) which can be activated through permanent microevolutionary changes in metal-tolerant species or through exogenously applied priming agents that may ensure plant acclimation and thereby elevated stress resistance.

Background and aims Thallium (Tl) is extremely toxic to all lifeforms and an emerging pollutant. Plants in the Brassicaceae family, including edible crops, have an enhanced capacity for Tl accumulation, even from soils with low thallium concentration. The most extreme Tl hyperaccumulator is Biscutella laevigata, capable of attaining >32,000 μg Tl g-1 DW in its leaves. Methods Biscutella laevigata from a non-metallicolous accession (Feltre, Italy) and a metallicolous accession (Les Malines, France) were subjected to a dosing experiment in hydroponics (0, 5, 30 μM Tl), followed by synchrotron-based µXRF analysis to elucidate tissue and cellular-level Tl distribution. Key results Flow cytometric data on the two used accessions showed the Feltre accession has a genome size twice of that of the Les Malines accession (256 and 125 pg/2C respectively), suggesting they are phylogenetically distant populations. The Feltre accession does not accumulate Tl (125 μg Tl g-1 DW on average in leaves) at the 5 µM Tl dose level, whereas the Les Malines accession had a mean of 1750 μg Tl g-1 DW, with peaks of 24,130 μg Tl g-1 DW at the 30 µM Tl dose level. At 30 µM Tl the non-metallicolous accession did not grow, and at 5 µM Tl showed reduced biomasss compared to the metallicolous one. In Les Malines accession, the synchrotron-based µXRF analysis revealed that Tl is localised in the vacuoles of epidermal cells, especially underneath trichomes and in trichome basal cells. Thallium also occurs in solid crystalline deposits (3–5 µm in size, ~40 wt% Tl) that are mainly found in foliar margins and under trichome bases. Conclusions Biscutella laevigata is an attractive model for studying Tl hypertolerance and hyperaccumulation on account of the extreme expression of this trait, and its marked intraspecific variability.
