In rice, there is a lack of comprehensive research on the functional aspects of the members of the () gene family. This study provides a comprehensive investigation of the gene family, covering phylogeny, gene structure, promoter analysis, expression analysis, subcellular localization, and protein interaction. Remarkably, we discovered a specific gene loss event occurred in the chloroplast-localized group IIa SHMTs in monocotyledons.

Taking rural dispersed sewage for research objects, the treatment effect and microbial community structure characteristics of a bio filter (BF) reactor was studied. At fixed time and location, the removal efficiencies of common pollutants were investigated. By using high-throughput sequencing method, the heterogeneities of microbial community structure in fillers and plant roots were analyzed.

In order to obtain the optimal conditions for ammonia nitrogen (AN) wastewater treatment by bio filter (BF), the effects of ratio of carbon to nitrogen (C/N), pH, and hydraulic load (HL) on the AN degradation were studied by Response Surface Methodology (RSM). Central Composite Design (CCD) experiments were conducted, and the response of the AN removal rates were fitted to a second-order polynomial model. The analysis of variance showed that the model was accurate and reliable.

Carbon nanotubes have attracted attention around the world because of their high sorption capacity for hydrophobic organic compounds (HOCs); however, the bioavailability of HOCs sorbed on carbon nanotubes to bacteria is not well known. In the present study, (14) C-labeled and unlabeled phenanthrene was spiked onto four kinds of multiwalled carbon nanotubes (MWCNTs) and aged for 60 d, and the mineralization of phenanthrene sorbed on MWCNTs was studied. The mineralization efficiencies of phenanthrene sorbed on the four kinds of MWCNTs were 2.

Article Synopsis
  • High suspended sediment (SPS) concentrations in Asian rivers, exacerbated by climate change, contribute to soil erosion and sediment resuspension, impacting the biodegradation of pollutants like phenanthrene (PHE).
  • The study utilized a 14C-respirometer system to analyze how different types of sediment—original sediment (OS), and two combusted sediments (S375 and S600)—affect the mineralization rates of PHE by Agrobacterium sp.
  • Results showed that the mineralization of PHE varied significantly based on the sediment's organic carbon content, with OS and S600 promoting higher mineralization rates compared to S375, indicating that the composition of SPS can influence the biodegradation process.

Heavy metal levels in the rural soils are associated with the quality of agricultural products. In this study, soil samples were collected from the rural soils of Beijing; distribution of As, Co, Cr, Cu, Hg, Mn, Ni, Pb, V, Zn and their changes over the last two decades have been investigated. The results indicated that the concentrations of Co, Cr, Mn, Ni, and V were primarily controlled by the parent materials of soils, while concentrations of Hg, As, Cu, Pb, and Zn were affected by anthropogenic activities.
