Summary: Heavy metals and metalloids are major soil pollutants that limit crop production worldwide. The exposure to these pollutants induces oxidative stress in plants and alters their biochemical and morphological characteristics. Plants have evolved complex physiological and cellular defense strategies to cope with heavy metal toxicity, such as sequestration and transportation of metals, activation of signaling pathways, and detoxification mechanisms. Understanding the toxicity, signaling pathways, and tolerance mechanisms of heavy metals will help in developing new crop varieties and improving phytoremediation.

Summary: Globally, the increasing effects of metal and metalloid toxicity are mainly attributed to anthropogenic causes, particularly soil contamination. Plants have evolved mechanisms such as hyperaccumulation, tolerance, exclusion, and chelation with organic molecules to overcome metal/metalloid stress, while omics research has enhanced understanding of plant genome and transcriptome plasticity in response to these stimuli.

Summary: Cadmium is a toxic pollutant that persists in soil and has negative effects on plant growth and metabolism. Plants have developed antioxidative defense responses and specific mechanisms to combat cadmium stress. Additionally, plant hormones play a crucial role in signal transduction pathways and overall growth and development of plants under toxic conditions.

Summary: Heavy metal pollution is a serious global environmental problem that affects plant insect resistance and pest occurrence. This study investigated the defense response of Fraxinus mandshurica seedlings to Hyphantria cunea larvae under Cd stress, focusing on chemical, physical, and elemental defense. The results showed that Cd-treated seedlings attracted H. cunea larvae but reduced their body weight and survival rate. The increase in attractant metabolites and the decrease in repellent metabolites in leaf volatiles were responsible for the high attractant activity to H. cunea larvae under Cd treatment. The study also identified a reduction in physical defense, chemical defense, and their combination in Cd-treated seedlings through TOPSIS analysis.

Summary: This study found that adding calcium and magnesium can increase the activity of toxic metals, leading to increased toxicity to plants, but also enhancing the alleviation effects on toxic metals. The research suggests that metal activity at the outer plasma membrane surface of root cells is a better predictor for plant response to toxicity.

Summary: The study showed that exogenous PGRs can alleviate the combined stress of uranium and cadmium on sunflowers by stimulating photosynthesis, reducing levels of active oxygen and lipid peroxidation, and enhancing antioxidant defense systems. Additionally, PGRs can increase the uptake of uranium and cadmium by sunflowers, improving their remediation efficiency for uranium and cadmium contamination in the soil.

Summary: Plant adaptive strategies have been shaped through interactions with various environmental factors, including metals/metalloids. The complexation of phenolics with metal(loid)s is an area of intense study in different scientific fields. This review summarizes the interactions between phenolics and metal(loid)s using the metallomic approach. It proposes the concept of metallophenolomics as a ligand-oriented subgroup of metallomics, which provides new prospects for multidisciplinary investigations of phenolic-metal(loid) interactions.

Summary: Recent research has demonstrated the promising utility of transition metal complexes with M-E bonds stabilized by multidentate ligands, where E represents a main group metal or metalloid element. Main group metal and metalloid ligands provide unique electronic and steric environments to transition metals, leading to remarkable catalytic activity and product selectivity. This perspective highlights the potential of these compounds as a new class of supporting ligands for transition metal catalysts in synthetic chemistry.

Summary: The presence of cadmium in soil can negatively impact plant and microbial activities, affecting plant growth and leading to agricultural constraints. However, microbial inoculants can help plants tolerate cadmium stress and enhance productivity. Microorganisms in the rhizosphere interact with plants through signaling mechanisms, aiding in plant growth and improving nutrient uptake.

Summary: The study found that the cadmium hyperaccumulator Sedum alfredii can inhibit the infestation of the black bean aphid by accumulating a large amount of cadmium. This protective effect may be related to the high concentration of cadmium in the plant's phloem.

Summary: Metal pollution has a significant impact on sustainable agriculture and food safety. This research focused on soybeans and examined the plant's defense mechanisms in response to various concentrations of cadmium, including extreme levels. The results showed that inhibited growth and activation of superoxide dismutase isoforms were dose-dependent. However, contrary to expectations, hydrogen peroxide levels, proline accumulation, and lipid peroxidation were suppressed as the metal doses increased. Furthermore, a non-linear response in cadmium accumulation was observed at 200 mg/l, along with peculiar responses of chitinase family members. This study emphasizes the importance of considering the dose of metal stress when studying plant defense responses.

Summary: In Norway spruce, the germination capacity and subsequent embryo development of somatic embryos are strongly influenced by the desiccation phase after maturation. Desiccation at 100% relative humidity significantly increases the germination capacity of embryos, while reducing the humidity has a negative effect on embryo development. The biosynthesis of polyamines and the activity of cell wall-modifying enzymes are regulated by water availability during desiccation. Some physiological characteristics can be used as markers of inappropriate humidity during somatic embryo desiccation.

Summary: This study aims to contribute to the understanding of the protective role of β-D-glucan under biotic stresses. The results show that the content of β-D-glucan and the expression of related genes are influenced in oat leaves infected with the fungal pathogen B. graminis. However, the changes in gene expression did not have a significant impact on the content of β-D-glucan. Some isoforms of β-1,3-glucanase were significantly accumulated in the infected leaves.

Summary: We investigated the contribution of two Arabidopsis dehydrin genes, DH1 and DH3, to cadmium stress tolerance in plants. Transgenic tobacco plants overexpressing DH1 and DH3 were compared with non-transgenic control plants under long-term and short-term cadmium stress. Our results showed that DH3 played a role in modulating cadmium uptake and detoxification, leading to increased cadmium absorption and retention in roots. DH3 overexpression also resulted in higher levels of non-enzymatic antioxidants and suppression of certain cadmium-responsive miRNAs. In contrast, DH1 did not significantly contribute to cadmium tolerance.

Summary: Although growth stimulation was observed in some plants at low doses of arsenic, few studies have examined this phenomenon in detail. This study investigated the effects of different concentrations of arsenic on the growth and physiological parameters of two maize cultivars. The results showed that one cultivar, MvNK 333, had a higher tolerance to arsenic and exhibited increased shoot elongation, biomass, and water content at specific doses of arsenic. The overall findings suggest that the stimulatory effect of low doses of arsenic may represent an adaptation mechanism related to water content regulation.
