The interactions between sugar maple (Acer saccharum, Marshall) and its microbial communities are important for tree fitness, growth, establishment. Despite recent progress in our understanding of the rhizosphere phyllosphere maple, many outstanding knowledge gaps remain. This review delves into relationships microbes, as climate change alters plant species distributions. It highlights multifaceted roles key such arbuscular mycorrhizal (AM) fungi pathogens, affecting distribution establishment novel habitats. Furthermore, this examines how different compartments contribute to fitness. Finally, it explores dispersal altered under changing environmental conditions can affect maple's ability migrate beyond current range, emphasizing scenarios associated with shifts.

Arbuscular mycorrhizal fungi (AMF) are obligate mutualists that can enhance nutrition and growth of their plant hosts while providing protection against pathogens. AMF produce spores hyphal networks carry thousands nuclei in a continuous cytoplasm, with no evidence sexual reproduction. This review examines the impact genomic technologies on our view genetics evolution. We highlight how genetics, nuclear dynamics, epigenetics these prominent symbionts follow trends preserved distant multinucleate fungal relatives. also propose new avenues research to improve understanding biology intricate genetic interactions hosts.

Arbuscular mycorrhizal fungi (AMF) have accompanied the majority of land plants since their evolution in Devonian period with a symbiotic alliance centered on nutrient exchanges. The exploration AMF genomes is providing clues to explain major questions about biology, evolution, and ecology. dynamics nuclei across fungal life cycle, abundance transposable elements, epigenome landscape are emerging as sources intraspecific variability, which can be especially important organisms no or rare sexual reproduction such AMF. These features been hypothesized support adaptability wide host range environmental changes. New insights plant-fungus communication iconic function phosphate transport were also recently obtained that overall contribute better understanding this ancient fascinating symbiosis.

Summary It is well understood that agricultural management influences arbuscular mycorrhizal (AM) fungi, but there controversy about whether farmers should manage for AM symbiosis. We assessed fungal communities colonizing wheat roots three consecutive years in a long‐term (> 14 yr) tillage and fertilization experiment. Relationships among mycorrhizas, crop performance, soil ecosystem functions were quantified. Tillage, fertilizers continuous monoculture all reduced richness shifted community composition toward dominance of few ruderal taxa. Rhizophagus Dominikia depressed by and/or fertilization, their abundances as correlated positively with aggregate stability nutrient cycling across or no‐tilled samples. In the field, yield was unrelated to abundance negatively richness. complementary glasshouse study, biomass enhanced inoculum from unfertilized, no‐till plots while neutral growth observed inoculated soils fertilized conventionally tilled plots. This study demonstrates contrasting impacts low‐input conventional practices on symbiosis highlights importance considering both when managing mycorrhizas more sustainable agroecosystems.

Summary Arbuscular mycorrhizal fungi (AMF) are ubiquitous plant root symbionts, which can house two endobacteria: Ca. Moeniiplasma glomeromycotorum ( Ca Mg) and . Glomeribacter gigasporarum Gg). However, little is known about their distribution population structure in natural AMF populations whether harbour other endobacteria. We isolated from environments conducted detailed analyses of endobacterial communities associated with surface‐sterilised spores. Consistent the previous reports, we found that Mg were extremely abundant (80%) Gg rare (2%) both environments. Unexpectedly, discovered an additional previously unknown level bacterial diversity within spores, extended beyond endosymbionts, bacteria belonging to 10 phyla detected across our spore data set. Detailed analysis revealed that: not limited Gigasporaceae family AMF, as thought; was driven by host genotype; a significant inverse correlation existed between all Based on these data, generate novel testable hypotheses regarding function biology proposing they might act conditional mutualists AMF.

Introduction The hyphosphere of arbuscular mycorrhizal (AM) fungi is teeming with microbial life. Yet, the influence nutrient availability or forms on microbiomes still poorly understood. Methods Here, we examined how community (prokaryotic, fungal, protistan) was affected by presence AM fungus Rhizophagus irregularis in rhizosphere and root-free zone, different nitrogen (N) phosphorus (P) supplements into compartment influenced communities. Results greatly communities both prokaryotic being most. Protists were only group microbes whose richness diversity significantly reduced fungus. Our results showed that type nutrients encounter localized patches modulate structure In contrast did not observe any effects (non-mycorrhizal) fungal composition. Compared to non-mycorrhizal control, zone (i.e., hyphosphere) enriched Alphaproteobacteria , some micropredatory copiotroph bacterial taxa (e.g., Xanthomonadaceae Bacteroidota ), characterized yet cultured Acidobacteriota subgroup GP17, especially when phytate added. Ammonia-oxidizing Nitrosomonas nitrite-oxidizing Nitrospira suppressed compartment, upon addition inorganic N. Co-occurrence network analyses revealed complex interconnected more keystone species present, amended phytate. Conclusion study form an important driver eukaryotic assembly hyphosphere, despite assumed a stable specific hyphoplane microbiome. Predictable responses will open possibility using them as co-inoculants fungi, e.g., improve crop performance.

ABSTRACT Temporal variation in community composition is central to our understanding of the assembly and functioning microbial communities, yet controls over temporal dynamics for microbiomes long-lived plants, such as trees, remain unclear. tree could arise primarily from seasonal (i.e., intra-annual) fluctuations or longer-term changes across years host plants age. To test these alternatives, we experimentally isolated plant microbiome using a common garden clonally propagated used amplicon sequencing characterize bacterial/archaeal fungal communities leaf endosphere, root rhizosphere two Populus spp. four seasons consecutive years. Microbial differed among (which accounted up 21% composition) was correlated with dissimilarity climatic conditions. However, also positively time, reflecting compositional shifts trees aged. Together, findings demonstrate that patterns both changes, which interact generate unique each year. In addition shedding light on important microbiomes, results suggest future studies should account background when testing drivers spatial responses environmental change. IMPORTANCE Microbiomes are integral health but have limited factors control how time. Especially little known about relative annual non-woody plants.
