Societal Impact Statement It is crucial to develop strategies for reducing our continued excessive global increases in fertilizer applications and offset CO 2 emissions. The pervasive underground hyphal networks of arbuscular mycorrhizal fungi (AMF) present an enticing bio‐stimulant carbon sink. We inoculated Sudan‐grass plants with eight genotypically distinct strains a model AMF species determine if strain identity affects plant growth storage. found that biomass, nutrient acquisition, stable soil inputs varied among strains, emphasizing the importance selection inoculants optimizing crop yield Summary Arbuscular are obligate root symbionts most improve by transferring nutrients into roots through hyphae. These represent sink soil; thus, it has been suggested these can also boost atmospheric storage, highlighting their potential role managing greenhouse In this study, we aimed whether certain genotypes nuclear organizations (homokaryons vs heterokaryons) associated higher rates host compared ( Sorghum × drummondii ) inoculation across Rhizophagus irregularis : four homokaryotic heterokaryotic strains. was grown chamber, which included 13 C‐CO pulse labeling track AMF. increased total belowground as well phosphorous, magnesium, manganese uptake host.

Long-Term Crop Rotation Revealed the Relationship Between Soil Organic Carbon Physical Fraction and Bacterial Community at Aggregate Scales

Microorganisms, Год журнала: 2025, Номер 13(3), С. 496 - 496

Опубликована: Фев. 24, 2025

Crop rotation enhances soil fertility and health by modulating microbial communities, with organic carbon (SOC) dynamics governed aggregate–microbial interplay. To date, the effects of different crop rotations on SOC fractions relevant bacterial communities at aggregate scales remain uncertain. Here, a 17-year field experiment was used to reveal maize monoculture (MM), soybean (SS), communities. Compared SS treatment, only MS treatment significantly increased particulate (POC) content scale. Nevertheless, higher mineral-associated (MaOC) contents were observed under MM treatments than treatment. The co-occurrence networks for macro- microaggregates divided into three main ecological clusters. specific taxa in Cluster 1 2 are involved fraction turnover within microaggregates, respectively. In total, Vicinamibacteraceae-driven community dominated MaOC process macroaggregates, whereas Actinobacteria- Pyrinomonadaceae-driven changed microaggregates. This study strengthens our understanding role accumulation practices.

Distribution, characteristics, and importance of particulate and mineral-associated organic carbon in China forest: a meta-analysis

Опубликована: Март 26, 2025

Forest soil organic carbon (SOC) plays a critical role in the global cycle, and increasing long-term forest storage is essential for sequestration. However, distribution drivers of mineral-associated (MAOC) particulate (POC) soils at continental scale remain poorly understood. Using 540 data points from 59 studies related to POC, MAOC, total SOC China's forests, we analyzed POC MAOC across type, depth further investigated their influencing factors. accounted more than 63% soils. Both increase with age, mixed forests showing faster growth compared monoculture forests. The MAOC/SOC ratio decreases age but increases depth, demonstrating dominance deeper Importantly, content continuously SOC, exhibits no upper limit, suggesting potential persistent accumulation. closely associated microbial biomass carbon, mainly plant litter biomass. are influenced by different environmental factors display distinct patterns types depths. Thus, differentiating respective responses climate change essential. sequestration China remains far saturation.

Arbuscular mycorrhizal fungal genotype and nuclear organization as driving factors in host plant nutrient acquisition and stable carbon capture

Summary Arbuscular mycorrhizal fungi (AMF) are obligate root symbionts of most plants that improve plant growth by transferring nutrients into roots through networks soil hyphae. These hyphal represent a carbon sink in soil; thus, it has been suggested these can also boost atmospheric storage, highlighting their potential role managing greenhouse emissions. In this study, we aimed to determine whether certain AMF genotypes and nuclear organizations (homokaryons vs heterokaryons) associated with higher rates host yield storage. We compared Sudan-grass ( Sorghum × drummondii ) inoculation across eight strains Rhizophagus irregularis : four homokaryotic heterokaryotic strains. was grown chamber, which included 13 C-CO 2 pulse labeling track AMF. increased total belowground biomass, as well phosphorous, magnesium, manganese uptake the host.
