Abstract Background and aims Plant-beneficial microbes may attenuate climate change-induced stresses on plants such as drought. We investigated the potential of beneficial microbial consortia (BMc) plant growth rhizosphere bacterial/archaeal community under Methods Seeds Zea mays B73 were inoculated with six plant-beneficial bacterial isolates either alone or combined in two three-member (BMc1, BMc2) before sowing loamy sandy substrates greenhouse. A known effective consortium (BMc3) was included positive control. Drought treatment established BMc treatments by omitting watering last five weeks period. The maize single determined. Colony-forming units (CFUs) inoculants evaluated selective plating, effects native assessed using 16S rRNA gene amplicon sequencing basal root tip grown loam. Results In both water conditions, CFUs inoculations higher at roots than tips. Under well-watered seed inoculation a isolate had no effect substrates. resulted shoot (but not root) compared to non-inoculated controls conditions zone most important driver for beta-diversity, followed while showed effect. Conclusion Our study suggests that has drought stress during growth.

In the European Union and worldwide there are a burgeoning markets for plant growth promoting microorganisms (PGPM) other biological agents as soil improvers, bio-fertilizers, bio-stimulants, control or bio-pesticides. Microbial have major share in this development. The use of such products is often advertised with promise contributing to sustainable agricultural practices by increasing crop yield offering an alternative substitute decrease dependency agriculture on hazardeous agrochemicals. contrast registered microbial protection products, PGPM that marketed EU improvers biostimulants, not strictly required proven minimum efficacy levels under field conditions. Manufacturers only ensure these do pose unacceptable risks human, animal health, safety environment. Uniform guidelines comparable EPPO - standards (European Mediterranean Plant Protection Organisation) test trials available. This paper attempts fill gap. It proposes trial design implementation, well recommendations type scope data collection evaluation. Selected research papers from literature were evaluated analyze, whether what extent requirements already met. majority had clear experimental followed proper Frequent deficiencies low number tested environments species, insufficient site agronomic management description missing humidity temperature. Using suggested assumed increase expressive power products.

Abstract Modulating the soil microbiome by applying microbial inoculants has gained increasing attention as eco-friendly option to improve disease suppressiveness. Currently, studies unraveling interplay of inoculants, root-associated microbiome, and plant response are lacking for apple trees. Here, we provide insights into ability Bacillus velezensis FZB42 or Pseudomonas sp. RU47 colonize microhabitats modulate their microbiome. We applied two strains plants grown in soils from same site either affected replant (ARD) not (grass), screened establishment selective plating, measured phytoalexins roots 3, 16, 28 days post inoculation (dpi). Sequencing 16S rRNA gene ITS fragments amplified DNA extracted dpi different microhabitat samples revealed significant effects on fungal β-diversity root-affected rhizoplane. Interestingly, only ARD soil, most abundant bacterial amplicon sequence variants (ASVs) changed significantly relative abundance. Relative abundances ASVs affiliated with Enterobacteriaceae were higher rhizoplane reduced both inoculants. Bacterial communities root endosphere but presence was indicated. Interestingly previously unobserved, responded increased phytoalexin content roots, more pronounced grass than soil. Altogether, our results indicate that rhizosphere competent, modulated perceived plants, which could make them interesting candidates an mitigation strategy ARD. Key points • Rhizosphere competent (mainly fungi) Inoculants abundance stronger

Societal Impact Statement Grape production relies signifcantly on agrochemicals, such as fertilizers and pesticides, to sustain vine health yield. However, excessive or improper use of these inputs leads detrimental environmental effects, including soil degradation, water contamination, biodiversity decline. To address this, research must explore sustainable alternatives. Enhancing the symbiotic interactions between grapevine rootstocks beneficial microorganisms offers a viable pathway. By fostering natural relationships, producers scientists can develop environmentally viticulture practices that strengthen resilience without compromising productivity. This approach also supports broader transition regenerative, ecologically balanced agricultural systems. Summary The productivity vineyards are influenced by complex surrounding microbiome. Emerging has highlighted pivotal role microbe‐rootstock alliances in modulating nutrient acquisition, water‐use efficiency, pathogen resistance. leveraging potential microorganisms, viticulturists optimize vineyard management enhance overall productivity, stability, sustainability. Through strategic selection with enhanced mycorrhizal associations targeted introduction plant growth‐promoting rhizobacteria, growers support adapting challenging conditions. Aditionally, manipulating rhizosphere microbiome, through techniques biofertilization reverse microdialysis, foster development robust, disease‐suppressive communities safeguard vines against biotic abiotic stressors. Integrating microbiome‐centric approaches into comprehensive strategies, potentially future rootstock genetic improvement programs, holds promise for improving grape yield, quality, long‐term viticultural

Introduction Understanding how pasture-crop rotation design influences long-term soil health and microbial dynamics is crucial for sustainable agroecosystems. Pasture-crop rotations may alleviate degradation, but their effects or legacy on rhizosphere microbiomes, including potential recruitment of plant-beneficial microorganisms, link to crop yield need be better understood. This study examines land use intensity grazed pasture influence prokaryotic diversity, composition, functionality, productivity. Methods A gradient intensities ranging from continuous cropping (CCG), short (SR) long (LR) rotations, permanent improved (PIP), natural grassland (NGL) were sampled in a field experiment established 1995 the Uruguayan Pampa. Moreover, two stages rotation, one year after sown with sorghum (SRS, LRS) years soybean (SRG, LRG), studied assess persistence pasture-derived legacies. Soil physicochemical biological properties measured evaluate along Bulk soil, soybean, communities analyzed across using 16S rRNA gene amplicon sequencing functional assays bacterial isolates. Results showed partial retention assessed through selected properties, i.e. organic C, total N, extractable protein content higher LRG compared CCG, while an intermediate response was observed SRG. LR preserved legacy, maintaining bulk community composition similar PIP distinct SR converged CCG diverged PIP. Soybean diversity strongly shaped by type inoculation Bradyrhizobium elkanii , overriding intensification legacy. Key taxa ( Streptomyces, Solibacillus, Sphingomonas ) linked functionality. Linking data rhizobacterial isolates that Pseudomonas Bacillus Microbacterium all exhibiting multiple activities vitro enriched rotations. Discussion highlights design, particularly duration plant services health, contributing towards development resilient
