Environmental pollution by heavy metals affects both urban and non-urban areas of Europe and the world. The use of bioindicator plants for the detection of these pollutants is a common practice. An important property of potential bioindicators is their easy availability and wide distribution range, which means that they can be practically used over a wide area. Therefore, common and widely distributed weeds: Trifolium pratense L., Rumex acetosa L., Amaranthus retroflexus L., Plantago lanceolata L., ornamental species Alcea rosea L., and Lolium multiflorum L. var. Ponto were selected as a potential bioindicators of heavy metals (Cd, Pb, Cu, Zn). Plants were exposed in the same soil conditions in three sample sites in the Poznań city. It was found that all species had heavy metal accumulation potential, especially A. rosea, P. lanceolata and L. multiflorum for Zn (BCF = 6.62; 5.17; 4.70) and A. rosea, P. lanceolata for Cd (BCF = 8.51; 6.94). Translocation of Cu and Zn was the most effective in T. pratense (TFCu = 2.55; TFZn = 2.67) and in A. retroflexus (TFCu = 1.50; TFZn = 2.23). Cd translocation was the most efficient in T. pratense (TFCd = 1.97), but PB was the most effective translocated in A. retroflexus (TFPb = 3.09).. Based on physiological response to stress, it was detected an increasing level of hydrogen peroxide (H2O2) in roots and leaves of all samples, with the highest in all organs of A. rosea. Enzymatic activity levels of CAT, APOX, and also the marker of polyunsaturated fatty acid peroxidation MDA, were higher after 6 weeks of exposure in comparison to control samples and varied in time of exposure and between species and exposure. After the experiment, in almost all samples we detected a reduction of chlorophyll content and relative water content, but in efficiency of photosynthesis parameters: net photosynthesis rate, intercellular CO2 concentration and stomatal conductance, we noted increased values, which proved the relatively good condition of the plants. The examined weeds are good bioindicators of heavy metal contamination, and their combined use makes it possible to comprehensively detection of environmental threats.

Rare earth elements were extensively employed for many years to improve plant growth in farming. However, their effect on plant’s behavior relies on their concentration and the plant species. The impact of low doses of lanthanum (La; 1–10 µM) on plant growth, mineral uptake, and the production of secondary metabolites was assessed in two Brassicaceae species (Cakile maritime and Brassica juncea) after 14 days of La exposure. The La accumulation potential was also evaluated. Results showed that both species were able to maintain good dry biomass production under La. C. maritima plants accumulated more La than B. juncea, and a higher accumulation was noticed in the roots (in both plant species). Accordingly to La accumulation in plant tissues, nutrient absorption was affected in C. maritima shoots and roots, whereas no severe effect on nutrient contents was noticed in B. juncea. Phenolic compounds increased in the aerial and underground parts of both species; thus, the accretion was more notorious in shoots of the highest La concentrations. The studied Brassicaceae species showed an ability to survive in a La-contaminated medium. However, according to tolerance index values, C. maritima was found to be more tolerant of La than B. juncea.

“…Limbarda crithmoïdes, well known as Golden samphire, is a succulent perennial coastal plant commonly found in the Mediterranean basin in salt water marsh areas (Zurayk and Baalbaki, 1996). It displays a fascinating capacity to tolerate high sodium concentrations in its aerial parts (Flowers and Colmer, 2008;Vicente and Boscaiu, 2020) allowing it to have salt, water, and metallic stress tolerance (Al Hassan et al, 2016;El-Sherbeny et al, 2021;Dridi et al, 2022a;2022b). L. crithmoïdes has long been collected for its medicinal properties and therapeutic uses.…”

The present work describes an efficient micropropagation and callus induction protocol of Limbarda crithmoïdes L. (Asteraceae), a halophyte species with medicinal and horticultural interests. The objective was to identify the culture media that support the best organogenesis and callogenic expressions of four types of aerial explants; nodal and internodal segments and leaf portions, by varying the mineral composition of twenty culture media by adding increasing concentrations of Na+ (from 0-100 mM) and K+ (from 0-50 mM). After two months of culture, parameters relating to the various expressions of organogenesis and callogenesis were measured. Results showed that the K+ and Na+ interactions affect the explants development. The combination of high concentrations of Na+ (50, 100 mM) and K+ (50 mM) ions allowed the most important regeneration of the axillary shoots (70.6-100%), root neoformation (82.6-96.1%) and callus induction (76.3-100%). Rooted plantlets with well-developed axillary shoots have been successfully acclimatized with a 93% of survival rate. The selected media would allow a large-scale multiplication of this medicinal species, without adding exogenous phytohormones, and could be used for the micropropagation of other threatened halophyte species or for the production of callus; rich in secondary metabolites.
