Stronger dispersal potential of alkaline phosphatase‐encoding bacteria ensures higher organic phosphorus mineralization rate

Abstract Scientific theory largely neglects linkage between organic phosphorus (Po) mineralization rate and dispersal potential of alkaline phosphatase‐encoding bacteria (PEB) containing the phoD gene. Different densities substrates (i.e. compacted soils, culture media, soil aggregates) were prepared molecular tools used to unveil relationship PEB Po rate. According morphological observations ecological studies, we found that stronger ensured a higher Higher rates in microaggregates than macroaggregates silt + clay, was related closely P fractions distributed heterogeneously aggregates. The gene abundance notably correlated with rate, rare mediated mineralization. Bradyrhizobium as identified genus dominated dramatically heterogeneous community, stochasticity (70.5%–89.5%) affected more on community assemblages PEB. showed other aggregates, indicated by weaker stability, species replacement, migration lower environmental constraint broader niche breadth. Overall, our results emphasize ensure these findings broaden understanding how maintain landscape function soils. Read free Plain Language Summary for this article Journal blog.

Soil Organic Carbon Increases With Decreasing Microbial Carbon Use Efficiency During Vegetation Restoration

Global Change Biology, Journal Year: 2024, Volume and Issue: 30(12)

Published: Dec. 1, 2024

ABSTRACT Microbial carbon (C) use efficiency (CUE) describes the proportion of organic C used by microorganisms for anabolic processes, which increases with soil (SOC) content on a global scale. However, it is unclear whether similar relationship exists during natural vegetation restoration in terrestrial ecosystems. Here, we investigated patterns CUE along 160‐year chronosequence (from farmland to climax forest) estimated stoichiometric modeling; additionally, examined between and SOC combined these results meta‐analysis. The combination indicated that decreased from 0.35 0.28. Surprisingly, increased decreasing because forest soils have low pH values high microbial phosphorus limitations compared early ecosystems, implying forests may not sequester as much expected. shift was most important predictor climate, plant, factors. changes were directly induced pH‐induced community. Alkaline acidification tended decrease CUE. This first large‐scale estimate highlights need strengthen sink management mature sustain their sequestration potential.

Soil Inorganic Phosphorus Is Closely Associated with pqqC- Gene Abundance and Bacterial Community Richness in Grape Orchards with Different Planting Years

Agronomy, Journal Year: 2025, Volume and Issue: 15(3), P. 666 - 666

Published: March 7, 2025

The high application rate and low utilization efficiency of inorganic phosphorus (Pi) fertilizer could lead to significant P accumulation in soil. Soil cycling is greatly affected by the planting time perennial fruit yards. However, mechanism which soil Pi fractions pqqC-harboring bacterial communities, their relationships, are vines, remains unclear. Here, fractions, relationships grape yards with 0.5, 4, 16 22 growth years, designated as Y0.5, Y4, Y16 Y22, were examined. results showed that increasing organic carbon (SOC) contents pH values, respectively, increased decreased. In addition, percentages labile moderately increased, whereas those stable soils abundance α-diversity pqqC decreased compared Y0.5. Y16, composition communities was altered significantly, showing a great difference Y4 Y22. At genus level, relative bacteria highly correlated fractions. Further structural equation modeling revealed between community richness gene transformation regulated pH. These findings suggest changes closely associated pH, abundance, SOC content orchards different years.
