Abstract Slow-growing bacteria play a crucial role in soil ecosystems, yet our understanding of their persistence complex environments remains limited. Do these organisms lack essential metabolic genes, or do they possess specific genes that enable survival under challenging conditions? Our study begins to fill this knowledge gap by analyzing the genomes four slow-growing isolated from tropical savanna soil, providing insights into capacities and adaptation mechanisms. findings revealed represent novel species, including new strains Bosea, Nocardioides, Cupriavidus, Enterobacter roggenkampii. Most encoded key pathways related central metabolism, particularly sugar amino acid suggesting slow growth may be an adaptive strategy. The also exhibited potential contributions vital biogeochemical processes, carbon, nitrogen, sulfur cycling, as well plant promotion. We identified 164 defense across 32 families at least one antimicrobial resistance (AMR) gene each strain, with strain CER55 showing highest number predicted AMR genes. Additionally, twelve biosynthetic clusters were three strains. combination mechanisms, resistance, secondary metabolite production indicates evolved multiple strategies thrive competitive microbial communities.

ABSTRACT Plants depend heavily on efficient nutrient uptake and utilization for optimal growth development. However, plants are constantly subjected to a diverse array of biotic stresses, such as pathogen infections, insect pests, herbivory, well abiotic stress like drought, salinity, extreme temperatures, imbalances. These stresses significantly impact the plant's ability take up use it efficiency. Understanding how maintain efficiency under conditions is crucial improving crop resilience sustainability. This review explores recent advancements in elucidating mechanisms underlying conditions. Our aim offer comprehensive perspective that can guide breeding stress‐tolerant nutrition‐efficient varieties, ultimately contributing advancement sustainable agriculture.

The principle of the "growth-defense trade-off" governs how plants adjust their growth and defensive strategies in response to external factors, impacting interactions among plants, herbivorous insects, natural enemies. Mineral nutrients are crucial modulating plant development through bottom-up effects. Emerging evidence has revealed complex regulatory networks that link mineral defense responses, influencing delicate balance between against herbivores. This review aims summarize recent advances elucidate impact nutrient availability on responses. Particularly, we focus status shapes resistance herbivores, delving into molecular mechanisms underlying this physiological process. Moreover, interplay various herbivore mechanisms, including physical protection, hormone signaling, metabolite production, volatile organic compound emissions deter herbivores or attract enemies, discussed. comprehensive sets stage for future investigations intricate crosstalk signaling which serves as a central mechanism guide sustainable pest management approaches, thereby promoting balanced agroecosystem health enhancing ecosystem productivity resilience.

Pathogens have to cope with oxidative, iron- and carbon(glucose)-limitation stresses in the human body. To understand how combined iron–carbon limitation alters oxidative stress responses, Aspergillus fumigatus was cultured glucose–peptone or peptone containing media supplemented not deferiprone as an iron chelator. Changes transcriptome these cultures were recorded after H2O2 treatment. Responses highly dependent on availability of glucose iron. Out 16 responsive antioxidative enzyme genes, only cat2 catalase–peroxidase gene upregulated more than two culturing conditions. The transcriptional responses observed metabolism also varied substantially cultures. Only extracellular siderophore production appeared important regardless conditions protection, while enhanced synthesis Fe-S cluster proteins seemed be crucial for treated iron-limited fast growing (glucose rich) Although pathogens host cells live together same place, their (e.g., occurrence stress) can different. Therefore, inhibition a universally biochemical process, like assembly, may selectively inhibit pathogen growth vivo represent potential target antifungal therapy.

ABSTRACT Previously, we identified BAR11, an uncharacterized protein from the biocontrol actinomycete Saccharothrix yanglingensis Hhs.015, as elicitor of plant immunity. BAR11 pretreatment significantly suppressed Valsa mali infection in apple ( Malus domestica ); however, its molecular function remained unclear, did mechanisms governing response apples to treatment. Here, demonstrate that functions a ferritin, defined by conserved four‐helical bundle structure, and enhances oxidative stress tolerance actinomycetes. Confocal microscopy revealed was secreted delivered into cells, where it sequestered labile ferrous iron (Fe 2+ ) inhibited uptake. Notably, treatment deficiency induced nearly identical transcriptional reprogramming homoeostasis‐related genes roots similar resistance phenotypes, suggesting triggers low iron‐mimicry state, which potentiates Transcriptomic analysis further supported disrupted expression while activating defence‐related ones. Moreover, WRKY family transcription factor MdWRKY40 responded robustly low‐iron treatments positively modulated BAR11‐induced against V. . Our findings reveal paradigm wherein ferritins act cross‐kingdom immune elicitors disrupting homoeostasis apple, providing mechanistic foundation for iron‐targeted strategies.

Invasive aspergillosis (IA) is a deadly fungal lung infection. Antifungal resistance and treatment side effects are major concerns. Iron chelators vital for IA management, but systemic use can cause effects. We developed nanoparticles (NPs) to selectively deliver the iron chelator deferasirox (DFX) treatment.
