Enhancing soil phosphate solubilization is a promising strategy for agricultural sustainability, while little known about the mechanisms of how microorganisms cope with differing phosphorus availability. Using combination genome-resolved metagenomics and amplicon sequencing, we investigated microbial involved in cycling under three treatments wheat-maize rotation system two natural reforestation treatments. Available was key factor shaping bacterial fungal community composition function across our sites. Membrane-bound quinoprotein glucose dehydrogenase (PQQGDH) exopolyphosphatases (PPX) governed agroecosystems. In contrast, genes encoding glycerol-3-phosphate transporters (ugpB, ugpC, ugpQ) displayed significantly greater abundance soils. The gcd gene PQQGDH found to be best determinant bioavailable phosphorus. Metagenome-assembled genomes (MAGs) affiliated Cyclobacteriaceae Vicinamibacterales were obtained from Their MAGs harbored not only but also pit low-affinity transporters. soils Microtrichales Burkholderiales. These contain ugp no gcd, thereby are indicative transporter strategy. Our study demonstrates that knowledge distinct acquisition strategies between could help linking processes cycling. IMPORTANCE microbiome player regulating processes. Identifying phosphate-solubilizing bacteria utilizing them release recalcitrant bound rocks or minerals have implications improving crop nutrient productivity. this study, combined functional sequencing analyze We differed these ecosystems. A dominated soils, observed further identified taxa contributed enhanced agroecosystem. microbes predicted beneficial increase bioavailability through practices.

The ecological clusters of soil organisms drive the ecosystem multifunctionality under long-term fertilization

Environment International, Journal Year: 2022, Volume and Issue: 161, P. 107133 - 107133

Long-term fertilization is known to impact the biodiversity and community structures of soil organisms, which are responsible for multiple ecosystem functions (multifunctionality). However relationship between alterations organisms multifunctionality remains unclear, especially in case long-term fertilization. To explore contribution organismal multifunctionality, we took samples from a nearly 25-year field experiment. Organic matter significantly improved multifunctionality. Ecosystem was found be closely linked communities within major ecological clustering (Module 1) according trophic co-occurrence network, rather than entire organisms. This indicated that clusters network were critical maintaining The application organic could enrich specialized increase interactions cluster. As result, our findings emphasize role controlling after fertilization, presenting novel perspective on link

Soil salinization has emerged as a major factor with an adverse influence on agricultural green development worldwide. It is necessary to develop high-efficiency and ecologically beneficial management measures for alleviating soil salinization. The experiment of application cow manure (CM), biochar (BC), bio-organic fertilizer (BIO) in light salinity was conducted investigate the remediation organic materials melon (Cucumis melo L.) by reducing availability saline ions shifting microbial community. Results showed that BC treatment significantly decreased EC values solution 19.23% 27.02% concentrations Na+, K+, Cl- 13.28%, 13.08%, 15.21%, respectively, followed CM BIO treatments. High-throughput sequencing identified amendments improved richness bacterial community increased relative abundances Acidobacteria Firmicutes 33.11% 111.2%, salt-tolerant genera Flavobacterium, Bacillus Arthrobacter 32.04%, 38.92% 35.67%, respectively. Additionally, Ca2+, K+ were negatively correlated Flavobacterium also most important factors driving changes structure communities. networks more complex treatments than CK, reflecting through nodes links higher average clustering coefficient, density modularity. This study provided comprehensive understanding improving fungal communities provides scientific support agriculture development.
