Summary: The spatial distribution of Zn and Cd in leaves of Arabidopsis halleri was determined using LA-ICP-MS. Referencing to internal standard elements was used to compensate for experimental issues. C-13 was found to be the most suitable element for referencing, stabilizing the distribution of Zn and Cd even in samples affected by experimental issues.

Summary: Pollution of the environment by heavy metals (HMs) is a global issue, affecting the health of all living organisms. Human activities, such as industrialization and urbanization, are the major causes of HM release into the environment. Traditional methods to reduce HMs in polluted environments are inefficient and expensive, while phytoremediation, using hyper-accumulator plants, is a highly efficient, cost-effective, and ecofriendly alternative.

Summary: This study investigated the influence of temperature on the rate and mechanisms of accumulation of cadmium (Cd) and zinc (Zn) on the surface of Aspergillus nigeroutlet boards. The results showed that the temperature dependence of the distribution of Cd and Zn in the plant was different, indicating different loading mechanisms in the xylem for Cd and Zn. Although Cd and Zn have partially similar transport pathways, the kinetics of absorption revealed that the temperature maximizing absorption rate was different between Cd and Zn. This study suggests the potential for efficient Cd phytoextraction using A. halleri ssp gemmifera in Cd and Zn co-existing environments.

Summary: Cadmium (Cd) is a major health concern worldwide due to its negative effects on soils, rendering them unsuitable for food and feed production. Phytoremediation has the potential to remediate Cd-polluted soils, but further understanding of the underlying processes is needed. This study comprehensively analyzed the response of A. thaliana and A. halleri to Cd stress, identifying co-expressed gene modules specifically associated with Cd presence. The results revealed that the Cd-associated genes in A. halleri are finely regulated and linked to a general response to chemical and other stimuli, while in A. thaliana, the upregulated genes are related to a general response to stimuli, and the downregulated genes are associated with root growth and development. Key genes associated with Cd were identified and may serve as targets for future research.

Summary: This study used weighted gene co-expression network analysis (WGCNA) to predict organ-specific co-expression networks in the root and shoot of Arabidopsis halleri. The results revealed the most enriched pathway, photosynthesis and photosynthesis-antenna proteins, in both the root and shoot. Additionally, root-specific pathways such as glucosinolate biosynthesis, autophagy, and SNARE interactions in vesicular transport, as well as shoot-specific pathway circadian rhythm, were identified. Hub and bottleneck genes in each module were screened and their possible involvement in heavy metal stress was validated. The analysis of co-expression modules along with protein-protein interactions (PPIs) confirmed some genes as potential candidates for plant heavy metal stress and biomarkers. These findings provide new insights into the pivotal functions of A. halleri's hyperaccumulative trait, opening up new avenues for future research on this species.

Summary: miRNAs are key players in mineral homeostasis, with differential expression patterns in response to Zn excess in Arabidopsis thaliana and the Zn-hyperaccumulator species Arabidopsis halleri. These differences reflect distinct regulatory pathways in nutrient requirements, response to stresses, and plant growth and development.

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: This study found that simulated herbivory enhances root foraging and uptake of cadmium in the metal-hyperaccumulating plant Arabidopsis halleri, particularly in plants from non-metalliferous origin. Plants from a metalliferous origin did not show preference in root allocation but exhibited enhanced Cd sharing between ramets when exposed to herbivory.

Summary: This pilot study aimed to compare the effects of zinc and nickel on the fatty acid profiles, oxidative stress and desaturase activity in two different species of Arabidopsis plants, one being a zinc hyperaccumulator and the other being a metal excluder. The results showed that significant changes in fatty acid composition were observed in both species, but the changes were metal-dependent and species-specific. These metal-induced changes in fatty acid composition could affect the fluidity and stability of membranes in the plants, potentially contributing to their metal tolerance or acclimation.

Summary: The study demonstrated the accumulation of Cd by Arabidopsis halleri ssp. gemmifera, with an increase in biomass, Cd, and Zn concentration in the plant over 103 days of experimentation. Soil Cd concentration significantly decreased, and the material balance showed Cd uptake by the plant and decrement from the soil ranging from 63.3% to 83.7% in each growth stage. Analysis revealed stable water-eluted and exchangeable forms of Cd, with a decrease in the fraction extracted with 0.1 M HCl, indicating its non-bioavailability.

Summary: This study investigated the concentration of nine heavy metals in Oreochromis niloticus and Ipomoea aquatica in Agodi reservoir, Nigeria. The results showed that the metals accumulated more in O. niloticus than in I. aquatica. Most of the examined metals exceeded the safety limit, and O. niloticus had lower tolerance for heavy metals. Additionally, metal concentration and ecological risk quotient were higher in the wet season for O. niloticus.

Summary: Environmental pollution can negatively impact sperm quality in birds, but tree sparrows have rapidly evolved adaptive and compensatory changes in sperm morphology and motility to cope with pollution over the past 65 years. Through genomics and transcriptomics analysis, researchers identified the PIM1 gene, which is associated with the rapid evolution of sperm phenotype. The duplicated PIM1 gene family showed testis-specific expression and played a crucial role in facilitating the rapid evolution of sperm in polluted areas.

Summary: Mercury is a toxic metal that easily accumulates in organisms and spreads through the food chain. The concentration of mercury in Scomber colias has significantly decreased over the past few decades, possibly due to environmental regulations and measures to reduce mercury emissions. Additionally, historical collections of biological specimens are valuable sources of information for monitoring the effectiveness of legislative measures on the environment.

Summary: The study revealed that self-incompatibility (SI) plays a key role in determining fertilization success in olive trees. Varieties from different SI groups can pollinate each other, while varieties from the same SI group cannot. The results demonstrate that the diallelic SI (DSI) system is crucial in determining pollination success among olive varieties in orchards.
