Summary: Abiotic stress reduces crop production worldwide. To recommend suitable genotypes for cultivation under water deficit and heat stress conditions, understanding the genetic basis and plant responses to these stresses and their interactions with the environment is crucial. In this study, the MGIDI index was used to identify abiotic-stress-tolerant wheat genotypes, while the WAASB and WAASBY indices were used to recognize high-yielding and stable genotypes. Twenty wheat genotypes were evaluated for their abiotic stress tolerance under various test conditions, and certain genotypes showed slight reductions in measured traits compared to the control group. The genotypes G12 and G17 were found to be the most stable candidates based on different indices, indicating their potential for improving productivity and stabilizing grain yield under optimal, water deficit, and heat stress conditions.

Summary: Nitrogen and phosphorus are crucial plant nutrients that can affect plant growth and crop yield. Understanding the interactions between nitrogen and phosphorus is important for studying plant adaptation to nutrient deficiencies. Lupins are unique plants that can develop new organs under N and P deficiencies, such as symbiotic nodules and cluster roots, which help mobilize otherwise unavailable phosphorus in the soil. The signaling mechanisms of N and P include factors like phytohormones and miRNAs, and the combination of these mechanisms reveals interactive regulation pathways in nodules and cluster roots, aiding in nutrient recycling processes.

Summary: This study examines the effect of aromatic amino acids on the optical properties of surface-modified silver nanoparticles. It reveals the formation of an interfacial charge transfer complex between silver and the ligand, as well as partial oxidation of surface silver atoms.

Summary: This study investigated the transport and retention of AgNPs capped with PVP of different molecular weights in porous media. It was found that higher molecular weight PVP provided stronger steric effect and electrostatic repulsive forces among PVP-AgNPs, enhancing their mobility.

Summary: Plant responses to stresses caused by metal nanoparticles are affected by cyclitols, which are absorbed and transported within the plant. Cyclitols induce the accumulation of sucrose and 1-kestose in seedlings, while (Bio)Ag NPs increase the concentrations of these sugars. Additionally, cyclitols decrease the concentrations of fructose and glucose. Similar effects were observed in seedlings developed from primed grains.

Summary: We investigated the use of POXA1b laccase from Pleurotus ostreatus for the oxidation of anthracene into anthraquinone. Different pathways can occur depending on the redox mediator combined to laccase, leading to different isomers. Carbon nanotubes were shown to act as redox mediators for anthracene oxidation into 9,10-anthraquinone, which was corroborated by theoretical calculations. The efficient adsorption of anthraquinones at CNT electrodes allows for low limit-of-detection of anthracene using laccase in solution, CNT-supported laccase, or laccase immobilized at magnetic beads.

Summary: This study elucidated the transfer pathways of Cd from soil to cacao nibs in a high Cd accumulating cacao cultivar. The results showed that the transfer from branches to nibs was more direct than from leaves to nibs. It also suggested that the main contribution of Cd in nibs came from the phloem tissues of the branches rather than leaf remobilization.

Summary: This study presents the design and characterization of novel electrode materials composed of multi-walled carbon nanotubes coated with glyconanoparticles functionalized with anthraquinone sulfonate. The modified electrodes were analyzed using scanning electron microscopy and cyclic voltammetry. The electrochemical behavior exhibited a stable pH-dependent redox signal specific to anthraquinone sulfonate. Immobilizing bilirubin oxidase onto these three-dimensional electrodes resulted in the electroenzymatic reduction of O2 to water with an onset potential of 0.5 V/SCE. A catalytic cathodic current of 174 µA (0.88 mA cm-2) at 0.1 V/SCE demonstrated that glyconanoparticles modified with anthraquinone sulfonate facilitated the interaction and orientation of bilirubin oxidase through electrostatic interactions.

Summary: Inorganic contaminants released from mining activities can have a negative impact on the surrounding ecosystems. Sulfuric acid, produced after the oxidation of primary sulfide minerals in ores, plays a significant role in the release of metals. However, secondary metal sulfates can form and control the fate of metals. Thallium (Tl), for example, can be trapped by Tl-jarosite and dorallcharite, secondary minerals found in Tl-rich sulfide deposits and mining areas. The study of the long-term behavior of Tl in soils at the Jas Roux site in France has provided new insights into the biogeochemical cycle of this metal.

Summary: Excess and limited trace metals in soils and plants can hinder crop yields and pose risks to the environment and human health. The combination of X-ray absorption spectroscopy (XAS) with isotope analyses is an emerging approach that can improve understanding of metal speciation and dynamics in soil-plant systems. This approach shows promise in providing insights into metal availability in soils and metal uptake and translocation in plants, although further research and methodological advancements are needed.
