Coupling phosphate-solubilizing bacteria (PSB) with P fertilizers, including polyphosphates (PolyP), was reported as eco-efficient approach to enhance use efficiency. Although PSB have been recently hydrolyze PolyP, the plant growth promoting mechanisms of PolyP-PSB co-application were not yet uncovered. This study aims evaluate effect a consortium (PSBCs) on growth, efficiency (PUE), and wheat yield parameters under PolyP (PolyB) application. Co-application PolyB-PSBCs significantly enhanced at 75 days after sowing (DAS) compared 30 DAS. A significant increase in shoot dry biomass (47%), inorganic content (222%), PUE (91%), root absorption (RPAE, 99%) noted unfertilized plants. Similarly, morphological traits DAS, while acid phosphatase activities (root rhizosphere), RPAE, increased The improved acquisition could be attributed lower investment production, induction activity roots rhizosphere soil co-application. Consequently, aboveground performance, which is reflected by nutrient contents (P 300%, K 65%), weight (54%), number (50%) spikes. Altogether, this provides relevant evidence that PolyP-PSBCs can an integrated environmentally preferred fertilization owing dual effects PSBCs PUE.

Abstract Background The microbiome plays a fundamental role in plant health and performance. Soil serves as reservoir of microbial diversity where plants attract microorganisms via root exudates. soil has an important impact on the composition rhizosphere microbiome, but greenhouse ornamental are commonly grown soilless substrates. While microbiomes have been extensively studied traditional agriculture to improve performance, health, sustainability, information about substrates is still limited. Thus, we conducted experiment explore peat-based substrate used container production Impatiens walleriana , popular plant. We investigated effects phenological stage fertilization level microbiome. Results under low rates were smaller produced more flowers than optimum high fertilization. top five bacterial phyla present Proteobacteria Actinobacteria, Bacteriodota, Verrucomicrobiota, Planctomycetota . found total 2,535 amplicon sequence variants (ASV) grouped into 299 genera. core was represented by only 1.8% (48) identified ASV. community influenced fertilizer levels. Phenological exhibited stronger influence Differential abundance analysis using DESeq2 ASVs significantly affected (enriched or depleted) levels at flowering. As observed for composition, effect function level. treatments did not affect alpha-diversity substrate. Conclusions In container-grown plants, main plant, agricultural inputs (fertilization) modulate structure differences across explained pH, organic carbon (TOC) fluoride, pH phosphate (PO 4 ).

Abstract Microbial communities in the plant rhizosphere—the soil region closely associated with roots— play critical roles shaping growth, defence, fitness, and ecosystem processes. Inoculation of plants specific rhizobacteria strains has shown promising potential for increasing crop yields. Rhizobacteria can also induce defences, resulting reduced insect growth reproduction, manipulate biochemistry to alter host-choice recruit natural enemies insects. We present a meta-analysis examining impact inoculation on fitness behaviour. Our findings indicate that generally reduces herbivore host choice behaviours. However, effect sizes varied significantly depending type (chewing versus sucking), host, rhizobacterial species. Bacillus spp. showed stronger effects than commonly studied Pseudomonas notably traits such as choice, leaf consumption, survival, reproduction chewing herbivores, while primarily impacting sucking herbivores by reducing reproduction. Single-strain inoculants tended perform better, especially suggesting strain incompatibility issues multi-strain inoculants. Furthermore, field trials less reduction compared experiments under controlled conditions, possibly due diversity environmental factors affecting inoculant persistence. Despite, very limited experimental data, studies observed attract parasitoid wasps predators plants. These results underscore need considering broader interactions when developing effective rhizobacteria-based pest management strategies. Understanding generalist rhizosphere aid synthetic microbial broad protective functions across various environments.
