Summary: This study demonstrates that Dc(RCd100) exhibits resistance compared to Dc1M(wt) in individual metal exposures, with different levels of sensitivity to various divalent metals. The Combination Index method is highlighted as an effective way to predict binary metal interactions in wild-type and Cd-resistant strains of D.chlorelloides, showing potential for bioremediation of metal-contaminated effluents.

Summary: This study aimed to identify and verify key genes in regulating Cd-induced hormesis in Arabidopsis thaliana. The results showed that hormesis occurred at certain concentrations of Cd, and the antioxidant defense system and photosynthesis system played roles in hormesis. The key gene ABF1 in the metabolic pathway of abscisic acid was identified and found to be essential for Cd-induced hormesis.

Summary: This study demonstrates the use of Cd2+ as a reactivity probe for compost extracts of fulvic acids, humic acids, and dissolved organic matter. The HA extract showed the highest reactivity among the extracts. Furthermore, the reactivity variation was the largest for HA, followed by FA and DOM extracts. A parameter, equivalent mass of fertiliser (m(EF)), was used to calculate the compost quality and compared with uncomposted organic fertiliser. The significance of this parameter was verified through a correlation analysis between binding extent and the effect of compost application on lettuce crop growth.

Summary: This paper investigates the physicochemical properties of pure Cd(OH)(2) and Cd(OH)(2)-CdO composite materials in depth. The cadmium sulfate octahydrate (3CdSO(4).8H(2)O) is used as a precursor for the first time in this work and never been used in previous works involving cadmium-based materials. Additionally, we present the first synthesis of Cd(OH)(2)-CdO by pneumatic spray pyrolysis deposition technique. The molarity has a clear impact on the formation of pure Cd(OH)(2) or Cd(OH)(2)-CdO phase mixture, and the films show high transparency and low resistivity.

Summary: Adsorption of Cd(II) on serpentine was investigated under typical environment conditions, involving common environmental anions and cations. The adsorption was negligibly affected by anion type, but was specifically modulated by cations. Mono- and divalent cations enhanced the adsorption by weakening electrostatic double layer repulsion, while trivalent cations suppressed the adsorption due to competitive adsorption. Fe3+ and Al3+ prevented Cd(II) adsorption by binding surface active sites, forming more stable inner-sphere complexes. This study provides insights into the influence of interfacial ion specificity on Cd(II) adsorption in terrestrial and aquatic environments.

Summary: P1B-type ATPases are important Cd2+/Cu2+ pumps in Aspergillus species, and their deletion increases sensitivity to Zn2+, Fe2+, or oxidative stress-induced by menadione sodium bisulfite and Fe3+. Heterologous expression of A. fumigatus PcaA enhances tolerance to Cd(2+) or Zn2+ stress in S. cerevisiae, while CrpA protects against oxidative stress and Fe2+ susceptibility indirectly. These P1B-type ATPases play a crucial role in protecting fungal cells from various stresses and may be potential drug targets.

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 role of LPR1 in Cd stress and found that the overexpression of LPR1 resulted in reduced primary root lengths, fresh weights, lengths of the non-root hair zone, and chlorophyll contents. It also triggered ROS bursts and reduced the entry of available iron into the cell, which induced the expression of IRT1 and exacerbated the Cd influx into plants. These findings highlight the pathway of LPR1-mediated plant response to Cd toxicity stress through the regulation of ROS and Fe homeostasis.

Summary: More than three billion people worldwide suffer from health issues caused by a lack of zinc and iron, leading to malnutrition. Biofortification is a potential solution to this problem, but understanding the molecular mechanisms involved is challenging. This review discusses the role of membrane transporters in the uptake, transport, storage, and redistribution of zinc and iron in plants, particularly in seed biofortification. The information provided will help plant breeders and molecular biologists understand the importance and implications of membrane transporters for seed biofortification.

Summary: Zinc deficiency has negative effects on the growth, biomass, and yield of sorghum. It also alters the expression of ZIP family transporter genes in both shoot and root tissues. The study found that certain SbZIP genes were highly induced by deficient zinc, and that these genes are closely related to the ZmZIP family of maize. The conservation of functional residues in the SbZIP family transporters suggests their importance in zinc uptake and transport. This research provides insights for improving zinc-use efficiency in sorghum.

Summary: Drought is a dangerous abiotic stress that negatively affects the growth, development, and yield of major cereals like finger millet. This study conducted physiological and molecular analyses to examine the responses of ten finger millet genotypes to drought. The results showed that drought significantly reduced the physiological traits of the genotypes, but the tolerant genotype (IC 87469) exhibited higher chlorophyll pigment contents, antioxidant enzyme activities, and proline accumulation compared to the susceptible genotype (IC 49940). The study also identified and analyzed four classical drought-responsive genes from the finger millet genome sequence. These findings provide valuable insights for future biotechnological approaches to improve drought tolerance in finger millet.

Summary: This study analyzed the changes in phenotypic, seed yield, biochemical, and molecular aspects of seven millets under different levels of zinc supply. The results showed that the phenotypic traits of all seven millets responded better to zinc concentrations of 0.50 to 2 μM compared to zinc deficiency (0.05 μM). Under zinc deficiency conditions, the millets had lower zinc contents in both the leaf and root tissues, increased antioxidant enzyme activity in the leaves, and increased root-related traits. The molecular studies indicated that higher expression levels of root-specific genes correlated with root phenotypic traits.

Summary: Deficiencies of phosphorus and zinc have a significant impact on finger millet, affecting plant biomass, root hair modification, nutrient uptake, and molecular responses. While phosphorus deficiency has a greater effect on biomass reduction compared to zinc deficiency, the combined deficiency of both phosphorus and zinc leads to an increase in root hair length and density. Phosphorus deficiency promotes zinc uptake, and zinc deficiency promotes phosphorus uptake. This study provides valuable insights for better management of phosphorus and zinc deficiency in finger millet.
