Abstract In nutrient-limited high-elevation ecosystems, plants rely on arbuscular mycorrhizal (AM) fungi to provide mineral phosphorus (P) in the form of phosphate (PO43-). AM gather these nutrients through associations with cycling bacteria (PCBs) that can mineralize PO43- from organic matter or solubilize mineral-bound P. The influence climate and other soil factors PCB interactions how communities affect fungal growth P levels remains unclear. We collected montane meadows over a 1000 meter elevation gradient three mountains created dataset shotgun metagenomes, marker genes, edaphic measurements. Soils at highest elevations had almost 50-fold lower 60% more hyphae than low-elevation soils. concentration pH influenced abundances taxonomically functionally diverse P-cycling exoenzyme including phosphatases, phospholipid turnover enzymes, genes for solubilization Actinobacteria, Acidobacteria, Proteobacteria were dominant PCBs, each correlated different functional guilds (rhizophilic, edaphophilic, ancestral). Our results argue an elevation-based trade-off microbial strategies. P-richer soils low elevations, microbiome is dominated by rhizophilic fungi, actinobacteria mineralizing phospholipids, less complex between PCBs fungi. P-scarser, weathered mountaintop favored ancestral mineral-associated fungal-PCB network. With continued warming, structure function ecosystems might shift resemble those elevations. This could disrupt long-established interactions, reducing prevalence groups, consequences both metabolic pathways produce total available plant communities.

Biostimulant application can be considered an effective, practical, and sustainable nutritional crop supplementation may lessen the environmental problems related to excessive fertilization. Biostimulants provide beneficial properties plants by increasing plant metabolism, which promotes yield improves quality of crops; protecting against stresses such as water shortage, soil salinization, exposure sub-optimal growth temperatures; promoting via higher nutrient uptake. Other important benefits include enzymatic microbial activities, changing architecture roots, solubility mobility micronutrients, enhancing fertility soil, predominantly nurturing development complementary microbes. are classified microbial, arbuscular mycorrhizae fungi (AMF), plant-growth-promoting rhizobacteria (PGPR), non-pathogenic fungi, protozoa, nematodes, or non-microbial, seaweed extract, phosphite, humic acid, other inorganic salts, chitin chitosan derivatives, protein hydrolysates free amino acids, complex organic materials.

Arbuscular Mycorrhizal (AM) symbiosis is integral to sustainable agriculture and enhances plant resilience abiotic biotic stressors. Through their symbiotic association with roots, AM improves nutrient water uptake, activates antioxidant defenses, facilitates hormonal regulation, contributing improved health productivity. Plants release strigolactones, which trigger spore germination hyphal branching, a process regulated by genes, such as D27 , CCD7 CCD8 MAX1 . recognition plants mediated receptor-like kinases (RLKs) LysM domains, leading the formation of arbuscules that optimize exchange. Hormonal regulation plays pivotal role in this symbiosis; cytokinins enhance colonization, auxins support arbuscule formation, brassinosteroids regulate root growth. Other hormones, salicylic acid, gibberellins, ethylene, jasmonic abscisic also influence colonization stress responses, further bolstering resilience. In addition health, soil improving microbial diversity, structure, cycling, carbon sequestration. This supports pH pathogen suppression, offering alternative chemical fertilizers fertility. To maximize ’s potential agriculture, future research should focus on refining inoculation strategies, enhancing compatibility different crops, assessing long-term ecological economic benefits. Optimizing applications critical for agricultural resilience, food security, farming practices.

Arbuscular mycorrhizal (AM) symbiosis is the oldest and most widespread mutualistic association on Earth involves plants soil fungi belonging to Glomeromycotina. A complex molecular, cellular, genetic developmental program enables partner recognition, fungal accommodation in plant tissues, activation of symbiotic functions such as transfer phosphorus exchange for carbohydrates lipids. AM fungi, ancient obligate biotrophs, have evolved strategies circumvent defense responses guarantee an intimate long-lasting mutualism. They are among those root-associated microorganisms able boost plants’ ability cope with biotic stresses leading mycorrhiza-induced resistance (MIR), which can be effective across diverse hosts against different attackers.

Summary Arbuscular mycorrhizal (AM) symbiosis is a mutualistic interaction between fungi and most land plants that underpinned by bidirectional exchange of nutrients. AM development tightly regulated process encompasses molecular communication for reciprocal recognition, fungal accommodation in root tissues activation symbiotic function. As such, complex network transcriptional regulation signaling underlies the cellular metabolic reprogramming host cells upon colonization. In addition to transcription factors, small RNAs (sRNAs) are emerging as important regulators embedded gene orchestrates development. controlling cell‐autonomous processes, plant sRNAs also function mobile signals capable moving different organs even or organisms interact with plants. produce sRNAs; however, their remains largely unknown. Here, we discuss contribution considering role colonized cells. We describe characteristics fungal‐derived evidence transfer functional two partners mutually modulate expression control symbiosis.

Filamentous plant pathogens pose a severe threat to food security. Current estimates suggest up 23% yield losses pre- and post-harvest diseases these are projected increase due climate change (Singh et al. 2023; Chaloner 2021; Stukenbrock Gurr Fisher 2012; Steinberg 2020). Understanding how filamentous emerge, spread adapt their hosts new environmental niches is crucial address devastating impact on global agriculture. Over the past two decades, genomics has emerged as central technology advance our understanding of population dynamics coevolution pathogens. The first genome pathogen, blast fungus Magnaporthe oryzae, was sequenced 20 years ago. Since then, pathogen not only provided deep genomic makeup populations, but fundamental for gene discovery, disease diagnostics, accelerated molecular biology. In merely we have witnessed several revolutions in field, including reference genomes many pathogens, scale thousands individuals, long-read chromosome conformation sequencing highly continuous assemblies recent intersections structural Here, commemorate 20th anniversary by presenting important technological advances (Fig. 1) lessons learned from decades genomics, with focus cereal diseases.
