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. In rhizosphere, AM known their nutrient acquisition improving stress tolerance.

Abstract Background Plant microbiomes play crucial roles in nutrient cycling and plant growth, are shaped by a complex interplay between plants, microbes, the environment. The role of bacteria as mediators 400-million-year-old partnership majority land plants and, arbuscular mycorrhizal (AM) fungi is still poorly understood. Here, we test whether AM hyphae-associated influence success symbiosis. Results Using partitioned microcosms containing field soil, discovered that hyphae roots selectively assemble their own microbiome from surrounding soil. In two independent experiments, identified several bacterial genera, including Devosia , consistently enriched on hyphae. Subsequently, isolated 144 pure isolates mycorrhiza-rich sample extraradical sp. ZB163 root hyphal colonizer. We show this AM-associated bacterium synergistically acts with mycorrhiza to strongly promote nitrogen uptake, mycorrhization. Conclusions Our results highlight do not function isolation plant-mycorrhiza symbiont can recruit beneficial support
