Summary: Engineered biochar loaded with MnOx from a Mn-hyperaccumulator species showed significantly enhanced Cd sorption capacity, with spectroscopic techniques and experiments elucidating the sorption mechanisms. Leaching of Mn was lower, Cd sorption was higher, and sorption was mainly through association with organic matter, carbonate, and MnOx. This sustainable and effective material proved to be an eco-friendly solution for remediating Cd-contaminated waters.

Summary: The study conducted the first growth experiment on Gossia species, revealing two new Mn hyperaccumulator plants. The dosing trial showed that G. fragrantissima accumulated Mn, Co, and Zn without signs of toxicity, and XFM analysis displayed the distribution patterns of these elements in plant cells.

Summary: The application of exogenous ABA had differential effects on heavy metal accumulation between Cd/Zn hyperaccumulator Sedum alfredii and non-hyperaccumulator Hylotelephium spectabile. The total biomass, chlorophyll content, and antioxidant capacity of the two species subjected to heavy metal stress were improved by exogenous ABA application. Exogenous ABA application significantly alleviated heavy metal-induced growth inhibition in co-contaminated soil, indicating its potential in phytoremediation of Cd-, Pb-, and Zn-co-contaminated soil.

Summary: This study evaluated the root and shoot response to nickel in hyperaccumulator and non-hyperaccumulator species. Hyperaccumulators did not show a decrease in root surfaces and biomass due to nickel exposure, while non-hyperaccumulators suffered from metal stress. The analysis of the root system helps clarify the plant response to nickel stress for bioremediation purposes.

Summary: Metalliferous soils with high content of metal compounds pose challenges to plant growth. The pseudometallophyte Noccaea caerulescens can grow on such substrates by implementing tolerance and accumulation of metal ions. In this study, the overexpression of two transporters, ZNT1 and NRAMP4, in plants affects metal accumulation, revealing mechanisms adopted by plants to survive in metalliferous soils.

Summary: This study investigated the role of intrinsic metals in hyperaccumulator biomass on the physico-chemical properties and performance of biochar in PDS activation. The results showed that different metals had different effects on the structure and performance of biochar, and played important roles in the degradation of imidacloprid.

Summary: This study investigated the changes in arsenic concentration, distribution, and speciation of the hyperaccumulator Pteris vittata at different growth stages, as well as the differences in metabolic profiling. The results showed that with aging, the redox potential increased in P. vittata, leading to the oxidation of arsenic and impacting its distribution. Furthermore, there was a positive correlation between arsenic concentration and flavonoid compounds.

Summary: Cadmium pollution is a major environmental issue, and this study investigated the detoxification mechanisms in a Cd-hyperaccumulating turnip landrace exposed to different Cd treatments. Enriched pathways such as flavonoid biosynthesis, sulfur metabolism, and glucosinolate biosynthesis were found to play important roles in Cd detoxification, while protein pathways like glutathione metabolism were also crucial. This research provides insights into the molecular mechanisms of Cd tolerance in turnips and highlights potential pathways for developing plants with reduced Cd accumulation for food or phytoremediation purposes.

Summary: Intercropping hyperaccumulators with crops is a promising method for remediating arsenic-contaminated soil. The response of intercropping hyperaccumulators with legume plants to different gradients of As-contaminated soil was studied. Results showed that soil As concentration significantly influenced the As uptake by plants. Intercropping Pteris vittata with Sesbania cannabina increased As accumulation, while intercropping with Cassia tora decreased it. The As concentrations in the seeds of both legume plants met the national food standards.

Summary: This study compared the accumulative properties of two ecotype hyperaccumulators of Bidens pilosa L. from different climate zones, revealing significant variations in Cd concentration and biomass between the ecotypes. The differences in Cd accumulation among ecotypes may be useful for identifying genes relevant to plant hyperaccumulation.

Summary: The study aimed to investigate zinc-cadmium tolerance in C. novae-hollandiae and compare it with C. cunninghamii. The results showed that C. novae-hollandiae accumulated high levels of zinc and cadmium in its shoots, with an increase in biomass. However, its tolerance for cadmium was limited. This study also suggested that C. novae-hollandiae may have different mechanisms for element uptake and tolerance compared to other well-studied zinc-cadmium hyperaccumulators.

Summary: Bidens pilosa L. is a widely distributed Cd-hyperaccumulator species with large biomass and fast growth rate. This study compared the Cd accumulation in two ecotypes (Hanzhong and Shenyang) collected from clean soils, and found that Hanzhong ecotype had higher Cd concentrations and biomass than Shenyang ecotype. The differences in Cd accumulation mechanisms between the two ecotypes could be important for future screening and constructing of ideal hyperaccumulators for phytoremediation purposes.

Summary: Narrowly endemic species are vulnerable to catastrophic events and less capable of adapting to environmental pressures. However, traits like preferential outcrossing and high fecundity can maintain genetic diversity and boost resilience. This study on the endangered Grevillea bedggoodiana found it to have preferential outcrossing and high genetic diversity, indicating reproductive health and genetic resilience.
