Summary: This study revealed the interaction between two proteins, Cfd1 and Nbp35, in L. donovani, forming a stable complex involved in the cellular process of Fe-S cluster biogenesis and transfer. The upregulation of Cfd1 and Nbp35 proteins in drug-resistant parasites leads to increased Fe-S protein levels, promoting parasite survival under drug pressure.

Summary: Fe-S clusters are important cofactors for metalloproteins involved in various cellular processes. Eukaryotes have acquired Fe-S protein biogenesis systems from bacteria through endosymbiosis, with these systems localized in mitochondria and plastids. Bacteria also possess components similar to eukaryotic CIA factors involved in Fe-S protein biogenesis.

Summary: Fe-S clusters are ancient and important for life processes. The biogenesis of Fe-S clusters involves iron acquisition, sulfur mobilization, and cluster formation. Two Arabidopsis DnaJ proteins, DJA6 and DJA5, play a crucial role in facilitating iron incorporation into Fe-S clusters during chloroplast Fe-S cluster biogenesis. Loss of these proteins leads to defects in chloroplast Fe-S protein accumulation and photosynthesis dysfunction. Evolutionary analysis shows that DJA6 and DJA5 are highly conserved in photosynthetic organisms and have a strong evolutionary relationship with SUFE1, SUFC, and SUFD.

Summary: Fe-S clusters are essential for the survival of eukaryotes, with independent biosynthesis pathways occurring in different compartments of the cell. Little is known about cytosolic Fe-S cluster biosynthesis in apicomplexan parasites, but it has been found that NBP35 in Toxoplasma gondii localizes to the outer mitochondrial membrane and is critical for parasite proliferation.

Summary: Sulfur is an essential macronutrient for plant growth and metabolism, and it plays diverse roles in their life cycles. It is connected to the homeostasis of essential micronutrients, such as iron, copper, zinc, and manganese. Sulfur is involved in the uptake, transportation, and distribution of these micronutrients, and it interacts with them in functional ways.

Summary: This study discovered a previously unknown hydrogenase in the cytosol of T. vaginalis, which can use cytochrome b5 as an electron acceptor. Trichomonads with overexpressed cytosolic hydrogenase showed decreased hydrogen excretion and increased excretion of methylated alcohols, suggesting that the cytosolic hydrogenase uses hydrogen gas as a source of reducing power for cytoplasmic reactions.

Summary: A novel nsLTP lineage is identified in green algae, which carries unique sequences and molecular features distinguishable from those in land plants. Further investigation on the Chlamydomonas nsLTPs shows their late zygotic stage expression patterns and verified canonical nsLTP properties such as fatty acids binding and proteinase resistance activities. This study not only reveals the existence of nsLTPs in green algae but also contributes to facilitating future studies on this enigmatic protein family.

Summary: 'Bacterial-type' ferredoxins have a cluster that enables electron transfer and biological processes. Peptide maquettes based on the cluster-forming motif have been used as ferredoxin models. This study explores the integration of a [4Fe4S]-peptide maquette into a H-2-powered electron transport chain and demonstrates its reconstitution under aerobic conditions. The integration of these artificial metalloproteins into a semi-synthetic electron transport chain is also demonstrated.

Summary: Iron-sulfur (Fe-S) clusters are versatile cofactors in biology, with the biogenesis of Fe-S proteins in the cytosol assisted by the cytosolic Fe-S protein assembly machinery, which includes proteins such as human ORAOV1 and YAE1. Structural and cluster binding studies showed that ORAOV1 and the YAE1-ORAOV1 complex can bind a [4Fe-4S](2+) cluster, suggesting their potential role in Fe-S cluster insertion into ABCE1.

Summary: A newly discovered plant mitovirus activates metabolic processes in quinoa to help them withstand drought, providing a new perspective for breeding crop plants. The study found changes in mitochondrial protein expression in infected plants, with up-regulation of functional modules involved in stress response and redox homeostasis, suggesting a potential mechanism for the observed higher tolerance to drought in infected plants. Further in-depth functional studies are needed to establish a causative link.

Summary: This review discusses the impact of microplastics (MP) on rhizosphere ecology, specifically focusing on the effects of MP on soil physical-chemical properties, plant physiology, and soil biodiversity. The long-term effects of MP on the interactions among soil organisms and plants are still not well studied, highlighting the need for further research on rhizosphere-MP interactions at a functional level.

Summary: Methanogenic archaea play a crucial role in the carbon cycle but are sensitive to reactive sulfite. Researchers have discovered a sulfite detoxification system in some methanogens, known as coenzyme F-420-dependent sulfite reductase (Group I Fsr), which combines an F420H2-oxidase with a sulfite reductase. The structural analysis of Fsr from marine methanogens revealed a unique fusion of a primitive sulfite reductase that converts a poison into an essential component of life.

Summary: Systematic studies have shown that the Hsp90 chaperone system and Fe/S protein biogenesis or iron regulation are interconnected. DJA5 and DJA6 are two chloroplast-localized proteins that act as iron donors in plastidial Fe/S protein biogenesis. In this study, the impact of Hsp90 chaperone, yeast DJA5-DJA6 homologs, cytosolic Ydj1, and mitochondrial Mdj1 on cellular iron-related processes was investigated using Saccharomyces cerevisiae. Depletion of these crucial proteins resulted in severe phenotypes, but did not have a critical in vivo impact on Fe/S protein biogenesis or iron regulation. Unlike plant DJA5-DJA6 iron chaperones, Ydj1 and Mdj1 did not bind iron in vivo, suggesting that zinc is used for their function under normal physiological conditions.

Summary: Coffee, being one of the most traded commodities globally, exhibits a strong interaction with arbuscular mycorrhizal (AM) fungi. This study explored the mycorrhizal phenotype of two important coffee cultivars under phosphorus limitation and found that fungal colonization significantly increased biomass, photosynthetic efficiency, and plant nutrition. This interaction also led to reorganization of major metabolic pathways.

Summary: This study aimed to investigate the physiological and biochemical responses of Populus nigra plants under drought and recovery, grown in soil with impaired nutrient bioavailability obtained by adding calcium oxide (CaO) to the substrate. Although the CaO treatment did not affect plant growth, treated poplars displayed an impaired inorganic ions profile in tissues under well-watered conditions. During water stress relief, the CaO-treated poplars exhibited a faster stomatal opening and a higher capacity to restore xylem hydraulic conductivity compared to not-treated plants, probably due to the higher osmolyte accumulation during drought. Our results suggest that CaO treatment promotes a faster and more efficient plant recovery after drought due to a modulation of ions homeostasis.

Summary: In anaerobic aromatic compound degrading microbes, class II benzoyl-coenzyme A (CoA) reductases (BCRs) reduce benzoyl-CoA to cyclohexa-1,5-diene-1-carboxyl-CoA (1,5-dienoyl-CoA) through a tungsten-bis-metallopterin (MPT) cofactor. This study provides experimental evidence for the Birch-like reduction mechanism via W(V)/radical intermediates and reveals the unique tetrahydro state of MPT cofactors essential for the reversibility of enzymatic Birch reduction.
