Intensive management is a common practice in agricultural and forestry ecosystems to improve soil quality crop yield by influencing nutrient supply microbiota; however, the linkage between nutrients bacterial community functional capacities intensively managed economic forests has not been well studied. In this study, we investigated properties such as available potassium (AK), nitrogen (AN), phosphorus (AP), ammonium (NH 4+ ), nitrate (NO 3- organic matter (OM), total (TN), (TP), diversity composition, potential functions of rhizome roots, microbiota across chronosequence Moso bamboo (Phyllostachys edulis) forests. Our results demonstrated that combined intensive (deep tillage, fertilization, material mulching) study caused significant increase concentrations AK, AN, AP, NH , NO OM, TN, TP (P < 0.05). However, they led remarkable decrease pH Such changes lowered Shannon root but did significantly affect composition capacity. Soil variation was predominantly mediated (TK) (15.02%), followed (11.29%) AK (11.13%). We further observed Nitrospirae accounted for approximately 50% pH, indicating its importance cycling, especially cycling. Accordingly, propose management-induced parameters reshaped structure keystone assemblage, leading differentiation microbial functions.

Sequencing of 16S rRNA genes has become a powerful technique to study microbial communities and their responses towards changing environmental conditions in various ecosystems. Several tools have been developed for the prediction functional profiles from gene sequencing data, because numerous questions ecosystem ecology require knowledge community functions addition taxonomic composition. However, accuracy these relies on information derived genomes available public databases, which are often not representative microorganisms present studied ecosystem. In addition, there is also lack predict redundancy communities.To address challenges, we Tax4Fun2, an R package redundancies prokaryotic sequences. We demonstrate that predicted by Tax4Fun2 highly correlated metagenomes same samples. further show higher accuracies than PICRUSt Tax4Fun. By incorporating user-defined, habitat-specific genomic information, robustness substantially enhanced. with determined simulated communities.Tax4Fun2 provides researchers unique tool investigate based data. It easy-to-use, platform-independent memory-efficient, thus enabling without extensive bioinformatics or access high-performance clusters profiles. Another feature it allows calculate specific functions, potentially important measure how resilient will be perturbation. implemented freely at https://github.com/bwemheu/Tax4Fun2.

Abstract Plants growing in soil develop close associations with microorganisms, which inhabit the areas around, on, and inside their roots. These microbial communities associated genes — collectively termed root microbiome are diverse have been shown to play an important role conferring abiotic stress tolerance plant hosts. In light of concerns over threat water nutrient facing terrestrial ecosystems, especially those used for agricultural production, increased emphasis has placed on understanding how conditions influence composition functioning ultimate consequences health. However, under will not only reflect shifts greater bulk community from plants recruit but also responses stress, include changes exudate profiles morphology. Exploring relative contributions these direct plant-mediated effects focus many studies recent years. Here, we review impacts affecting specifically flooding, drought, nitrogen phosphorus availability, that interact ultimately shape microbiome. We conclude a perspective outlining possible directions future research needed advance our complex molecular biochemical interactions between soil, plants, microbes determine stress.

Plant growth-promoting can promote growth use their own metabolism to solubilize phosphates, produce hormones fix nitrogen, they directly affect metabolism. PGPR also increase absorption of water nutrients, improving root increasing enzymatic activity; moreover, other microorganisms as part a synergistic effect improve plants, promoting or suppressing pathogens.

Phosphate-(P)-solubilizing microorganisms (PSM) are important drivers of P cycling in natural and agro-ecosystems. Their use as plant inoculants to improve acquisition crops has been investigated for decades. However, limited reproducibility the expected effects, particularly under field conditions, remains a major challenge. This study demonstrates that form nitrogen fertilization significant impact on performance various fungal bacterial PSM maize grown neutral alkaline soils with availability. Under these high soil pH-buffering capacity frequently limits efficiency nutrient mobilization, mediated by roots via rhizosphere acidification. In pH range between 7.0 8.0, nitrate promoting alkalinisation further aggravates this problem. Accordingly, greenhouse experiments, six strains Pseudomonas, Bacillus, Paenibacillus, Streptomyces, Penicillium proven P-solubilizing potential, completely failed promote calcareous Loess sub-soil 7.6 rock phosphate (Rock-P) sparingly soluble source. after replacement ammonium, stabilized nitrification inhibitor 3,4-dimethylpyrazole-phosphate (DMPP), five out seven (comprising 12 strains) exerted beneficial effects growth reached up 88% shoot biomass production control supplied triple-superphosphate (TSP).
