Summary: This study examined the accumulation of rhenium in plants and proposed a method for recovering it from plant tissue, using infrared spectroscopy and scanning electron microscopy for evaluation. It was found that rhenium is mainly stored in plant vacuoles in the form of water-soluble potassium perrhenate, and the proposed aqueous extraction procedure demonstrated almost complete rhenium recovery.

Summary: This study aims to screen Noccaea caerulescens lines with high cadmium phytoextraction efficiency and investigate differences in cadmium species and distribution in the leaves. The results showed that there are wide variations in biomass production and cadmium accumulation capacity among different lines, and cadmium-thiol complexes play a crucial role in cadmium detoxification.

Summary: This study investigated the use of hyperaccumulating plants to remediate TME contaminated sites and found that TME accumulation is not directly correlated with soil TME concentrations or bioavailability, suggesting a more plant-driven accumulation pattern. Habitat environment also influences a population's phytoextraction efficiency.

Summary: The study found that some native plants in the typical gold mining area on the Qinghai-Tibet Plateau have strong accumulation ability for As, Cd, Pb, and Zn, showing high tolerance to these elements. Among them, Geranium pylzowianum is a promising candidate for treating As, Potentilla saundersiana is suitable for handling Cd and Pb, and Elymus nutans is better for stabilizing multiple PTEs.

Summary: This study evaluates the geology and flora of ultramafic areas on the islands of Rhodes and Cyprus and provides new analytical information about plant species and soils. The study confirms the presence of nickel hyperaccumulating species on Cyprus but not on Rhodes. The concentrations of other elements in the collected plant species are within the ranges observed in ultramafic plants worldwide. The conservation of endemic plant species in ultramafic areas is of great importance.

Summary: Kenaf is a potential crop for the remediation of heavy metal-contaminated soil due to its ability to uptake and transfer heavy metals such as cadmium (Cd). This study investigated the differences in Cd uptake, translocation, and accumulation among different kenaf cultivars. The results showed that the phloem had the highest Cd accumulation and transfer capability. Certain kenaf cultivars were able to uptake approximately 35 to 65 g of Cd per hectare of soil. Fuhong 952, Fuhong 992, and Fuhong R1 were identified as Cd accumulators for the phytoremediation of Cd-contaminated soil based on their agronomic traits and Cd bioaccumulation capacity.

Summary: Some plant species can tolerate and accumulate high levels of metals or metalloids in their tissues as a defense mechanism. These plants also synthesize specialized metabolites that act as organic defenses. The variation in the composition and concentration of these metabolites, known as chemodiversity, has received little attention in the elemental defense hypothesis.

Summary: The phytoextraction strategy of harvesting dead leaves allows for continuous phytoremediation and cost-saving in disposing of hazardous plant residues. This study suggests that the accumulation of cadmium (Cd) in leaves is closely associated with leaf senescence, and further research should focus on regulating leaf senescence to enhance Cd accumulation and phytoextraction efficiency.

Summary: This paper investigates the accumulation and distribution of Cu and Pb in Helichrysum splendidum to evaluate its potential for phytoremediation of Cu- and Pb-contaminated soils. The study found that the plant can accumulate high concentrations of Cu and Pb, with Cu being primarily accumulated in the roots and Pb being translocated to the shoots. The tolerance mechanism of the plant was attributed to chelation and free radical scavenging through the production of phenolic compounds.

Summary: This study investigated the feasibility of using Alyssum murale for phytoremediation of Ni-contaminated soils with different characteristics. It was found that the most efficient combination of treatments would take 246 years to reach the target Ni concentration, while an optimized plant-soil system could achieve the same reduction in 9 years, although challenges remain for field application.

Summary: The research suggests that many plant species growing on metalliferous soils can accumulate and tolerate high levels of nickel, a trait that has evolved independently multiple times in different plant families. Analysis reveals the presence of genes encoding functions related to nickel hyperaccumulation in these species, including biosynthesis of specialized metabolites and cell wall organization. Additionally, high expression of IREG/Ferroportin transporters is recurrently associated with nickel hyperaccumulation in plants.

Summary: A new class of ecocatalyst, Eco-Pd, was prepared using a new process derived from biosorption technology with roots from aquatic and wetland plants, materials rich in lignin, and wastes rich in tannins. The presence of higher-oxidation-state palladium species, K2PdCl6, was observed in the formed Eco-Pd. This new generation of catalysts, with advantages such as no copper, ligands, additives, lower Pd loading, use of green solvents, and biosourced Pd and base, showed remarkable practical utility in Sonogashira reaction and can be easily recycled and reused through biosorption.

Summary: The Cunoniaceae in New Caledonia have 91 endemic species that hyperaccumulate multiple metals, making them an ideal model system for studying the hyperaccumulation phenomenon. XRF scanning revealed differences in Mn and Ni accumulation in different species, with Pancheria reticulata showing Mn concentration in hypodermal cells and P. xaragurensis mainly accumulating Ni in and around the epidermis. This suggests different ecophysiological adaptations in these species.

Summary: An innovative methodology using successive biosorption experiments was implemented to remove arsenic from aqueous solution. Fe(II) biosorption was conducted using a variety of biomaterials, and Pistia stratiotes was chosen as the most effective for As(V) removal. After oxidizing the biosorbent into Fe(III), a 92% removal efficiency and a maximum biosorption capacity of 5.1 mg.g(-1) were achieved. The adsorption mechanisms for iron and arsenic were studied using theoretical models, and the Langmuir isotherms and pseudo-second-order kinetics models showed excellent linearity and robustness. These promising results have been applied to a pilot project for As(V) removal from the Russec river in the Orbiel Valley, France.

Summary: The assembly of island plant communities is influenced by immigration, speciation, and extinction. This study focused on the origin of the New Caledonian Grevillea, a largely Australian genus. The analysis of plastid genes and a low-copy nuclear gene revealed that the New Caledonian Grevillea are allotetraploids resulting from hybridization events between two or three distinct parents. The study also highlighted the ecological and morphological differences between the two groups of New Caledonian Grevillea.
