High-emission socioeconomic pathways threaten phoD-harboring bacterial communities in cold ecosystems

Research Square (Research Square), Год журнала: 2025, Номер unknown

Alkaline phosphatase gene (phoD) harboring microbial communities drive organic phosphorus (P) mineralization, regulating plant P availability and ecosystem productivity. However, their global distribution pattern, key environmental drivers, responses to climate change remain poorly understood. Here, we conducted a meta-analysis of phoD amplicon sequences from 3,175 samples spanning diverse ecosystems worldwide, revealing higher diversity in colder more arid ecosystems. Climate (temperature, humidity) pH emerged as determinants, structuring distinct ecological clusters. Random forest models predicted that under high-emission scenarios (SSP585, + 3.8 8.6°C increment air temperature), warm-, humid-, alkaline-associated clusters will expand, while cold-adapted may decline by 84.3%, particularly vulnerable cold grassland alpine desert soils. Comparative genomic analysis further revealed P-starvation response inorganic P-solubilization frequencies warm-adapted taxa. These findings provide new insights into the adaptation phoD-harboring highlight potential disruptions cycling change, emphasizing need for conservation strategies protect functional communities.

Soil pH and Nutrient Stoichiometry as Key Drivers of Phosphorus Availability in Crop Rotation Systems

Agronomy, Год журнала: 2025, Номер 15(5), С. 1023 - 1023

Crop rotation systems profoundly influence soil phosphorus (P) dynamics through physicochemical and microbial interactions. The mechanisms regulating P availability under various rotational practices remain poorly understood. This five-year field experiment investigated the effects of four (WM: wheat–maize; WP: wheat–peanut; WS: wheat–soybean; MV: maize–hairy vetch) on fractions, phosphatase activities, P-cycling gene abundance, their interactions with properties. WM substantially reduced pH (6.29) while increasing labile fractions (Ca2-P) moderately (Al-P, Fe-P, Ca8-P), which was attributed to enhanced acid activity. WP elevated (8.13) but due calcium–P immobilization. MV stimulated cycling, exhibiting highest phoD (2.01 × 106 copies g−1) phnK (33,140 linked green manure-induced activation. Redundancy analysis identified pH, total nitrogen, stoichiometric ratios (C/N N/P) as key shared drivers enzymatic Partial least squares path modeling (PLS–PM) indicated that crop directly regulated modulation (r = −0.559 ***) C/N ratio 0.343 indirectly Lower (<10) across all regimes amplified carbon limitation in process transformation, indicating exogenous inputs appropriate stoichiometry should be optimized. results this study inform selection suitable patterns for sustainable agriculture.
