Abstract Root-associated microbes can alleviate plant abiotic stresses, thus potentially supporting adaptation to a changing climate or novel environments during range expansion. While change is extending species fundamental niches northward, the distribution and colonization of mutualists (e.g., arbuscular mycorrhizal fungi) pathogens may constrain growth regeneration. Yet, degree which biotic factors impact performance associated microbial communities at edge their remains unclear. Here, we use root microscopy, coupled with amplicon sequencing, study bacterial, fungal, root-associated from sugar maple seedlings distributed across two temperate-to-boreal elevational gradients in southern Québec, Canada. Our findings demonstrate that soil pH, Ca, distance trees are key drivers communities, overshadowing influence elevation. Interestingly, changes fungal community composition mediate an indirect effect pH on seedling growth, pattern consistent both sites. Overall, our highlight complex role shaping tree-microbe interactions, turn correlated growth. These have important ramifications for tree expansion response shifting climatic niches.

Abstract The soil microbiome is highly diverse and comprises up to one quarter of Earth’s diversity. Yet, how such a functionally complex influences ecosystem functioning remains unclear. Here we manipulated the in experimental grassland ecosystems observed that diversity microbial network complexity positively influenced multiple functions related nutrient cycling (e.g. multifunctionality). Grassland microcosms with poorly developed networks reduced richness had lowest multifunctionality due fewer taxa present support same function (redundancy) lower different (reduced functional uniqueness). Moreover, explained pointing significance communities. These findings indicate importance interactions within among fungal bacterial communities for enhancing performance demonstrate extinction ecological associations belowground can impair functioning.

Arbuscular mycorrhizal (AM) fungi gain access to nutrient patches outside the rhizosphere by producing an extensive network of fine hyphae. Here, we focused on establishing mechanism which AM fungal hyphae reach discrete organic with a cohort functional bacteria transported in biofilm their surface. We investigated mechanisms and impact translocation phosphate solubilising (PSB) along bespoke microcosms. An vitro culture experiment was also conducted determine direct hyphal exudates upon growth PSB. The extraradical can transport PSB phosphorus (P) enhance P mineralisation both under soil conditions.

Summary The plant endosphere is colonized by complex microbial communities and microorganisms, which colonize the interior at least part of their lifetime are termed endophytes. Their functions range from mutualism to pathogenicity. All organs tissues generally bacterial endophytes diversity composition depend on plant, organ its physiological conditions, growth stage as well environment. Plant‐associated in particular endophytes, have lately received high attention, because increasing awareness importance host‐associated microbiota for functioning performance host. Some endophyte known mostly lab assays, genome prediction few metagenome analyses; however, we limited understanding planta activities, particularly considering micro‐environments dynamics conditions. In our review, present recent findings environments, conditions colonization. Furthermore, discuss functions, interaction between plants methodological limitations research. We also provide an outlook needs future research improve role colonizing traits ecosystem functioning.

Candida albicans is a major fungal pathogen of humans. It exists as commensal in the oral cavity, gut or genital tract most individuals, constrained by local microbiota, epithelial barriers and immune defences. Their perturbation can lead to outgrowth development mucosal infections such oropharyngeal vulvovaginal candidiasis, patients with compromised immunity are susceptible life-threatening systemic infections. The importance interplay between fungus, host microbiota driving transition from C. commensalism pathogenicity widely appreciated. However, complexity these interactions, significant impact fungal, variability upon disease severity outcome, less well understood. Therefore, we summarise features fungus that promote infection, how genetic variation clinical isolates influences pathogenicity.

Abstract The gut microbiome consists of a multi-kingdom microbial community. Whilst the role bacteria as causal contributors governing host physiological development is well established, fungi remains to be determined. Here, we use germ-free mice colonized with defined species bacteria, fungi, or both differentiate on assembly, immune development, susceptibility colitis, and airway inflammation. Fungal colonization promotes major shifts in bacterial ecology, has an independent effect innate adaptive young mice. While exclusive fungal insufficient elicit overt dextran sulfate sodium-induced co-colonization increase colonic Ovalbumin-induced inflammation reveals that bacterial, but not necessary decrease inflammation, yet selectively macrophage infiltration airway. Together, our findings demonstrate for ecology functionality, therefore prompt inclusion therapeutic approaches aimed at modulating early life microbiomes.

Weed management is an arduous undertaking in crop production. Integrated weed management, inclusive of the application bioherbicides, emerging control strategy toward sustainable agriculture. In general, bioherbicides are derived either from plants containing phytotoxic allelochemicals or certain disease-carrying microbes that can suppress populations. While have exhibited great promise deterring seed germination and growth, only a few vitro studies been conducted on physiological responses they evoke weeds.
