Summary: Iron oxides, specifically Feo, play a crucial role in stabilizing aggregate-associated organic carbon and limiting the complexity and aromaticity of soil organic matter (SOM). The delta 13C values in smaller aggregate fractions were lower than larger ones, indicating less microbial utilization. The Feo and Fe-bound OC contents were higher in smaller aggregate fractions, while Fec increased with aggregate size. Polysaccharides and the ratio of aromatic-C/aliphatic-C also increased with aggregate size. Feo had a positive correlation with Fe-bound OC and a negative correlation with Fec in all aggregate fractions.

Summary: This study combines dual stable isotope analysis and ultraviolet-visible spectral characterization to elucidate the mechanisms of iodine enrichment in groundwater in the central Yangtze River basin, China. The results show that the biodegradation of high molecular weight organic compounds promotes the reductive dissolution of amorphous Fe (oxyhydr)oxides, while fermentation of small-molecule organic compounds triggers the release of iodine into groundwater. The findings provide new insights into the mechanisms of iodine enrichment in Quaternary alluvial-lacustrine aquifers.

Summary: Many studies have examined the redox behavior of sorbed ferrous ions on mineral surfaces, but few have investigated the formation of hydroxyl radicals during Fe(II) oxidation at circumneutral pH. This study found that the production of hydroxyl radicals was significantly higher in Fe(II)/α/γ-Al2O3 systems compared to dissolved Fe(II) alone. However, the production of hydroxyl radicals slightly decreased in Fe(II)/α-FeOOH/α-Fe2O3 systems. Mineral types and solution pH strongly influenced Fe(II) oxidation and hydroxyl radical production, which in turn impacted phenol degradation.

Summary: Agricultural intensification driven by land-use changes has caused continuous and cumulative soil acidification throughout the global agroecosystem. This study used metagenomic analysis to investigate the microbial community composition and function associated with soil acidification in rice-wheat and rice-vegetable rotations. The results showed that the conversion to rice-vegetable rotations resulted in decreased soil pH and increased acid saturation ratios. The microbial community composition in rice-vegetable rotations was enriched in taxa exhibiting dehydrogenation functions and was more dependent on hydrogen, aluminum, and nitrate nitrogen.

Summary: This study analyzed the influencing factors of cropland soil acidification using the example of cropland in the Sichuan Basin of China. The results showed that precipitation was the main factor causing soil acidification. Additionally, soil pH decrease was primarily buffered by soil carbonates and secondarily by soil CEC, with soil carbonates becoming the main buffering agent when their content exceeded 36.76 g kg(-1). These findings emphasize the importance of formulating precipitation-based optimizing agronomic management practices to prevent or mitigate cropland soil acidification.

Summary: This study investigated the effects of crop domestication on root functional traits and trait plasticity in response to neighboring plants. The authors found that wild barley had higher root functional traits and acid phosphatase activity, but lower root exudation of carboxylates and mycorrhizal colonization compared to domesticated barley under low P supply. Wild barley exhibited larger plasticity in root traits, while domesticated barley showed greater plasticity in root exudates and mycorrhizal colonization. The combination of wild barley and faba bean showed higher P uptake benefits under low P supply. These findings provide valuable insights for barley breeding and species selection to enhance P uptake.

Summary: This research aimed to uncover the detoxification mechanisms of rice in response to Cd stress through physiological, transcriptomic, and molecular approaches. The results showed that Cd stress inhibited rice growth, caused Cd accumulation, H2O2 production, and cell death. Transcriptomic sequencing revealed that glutathione and phenylpropanoid were the major metabolic pathways under Cd stress. Physiological studies demonstrated increased antioxidant enzyme activities, glutathione, and lignin contents under Cd stress. q-PCR results showed upregulation of genes related to lignin and glutathione biosynthesis, and downregulation of metal transporter genes in response to Cd stress. Further pot experiment confirmed the causal relationship between increased lignin and reduced Cd in rice.
