Project description:The potential of the earthworm Eisenia andrei to reduce soil methanogens, and thus methane emissions to the atmosphere, were assayed in a microcosm experiment. Soils were incubated for 2, 4 and 6 months. We measured microarray parameters (methanogenic diversity) at the start of incubation, as well as after 2, 4 and 6 months of incubation in microcosms with or without earthworms. Methanosarcina barkeri was the most abundant genus that was revealed by AnaeroChip in our experiment.

Project description:Pentachlorophenol (PCP) as a widely used pesticide is also considered to be an endocrine disruptor. Molecular effects of chemicals with endocrine disrupting potential on soil invertebrates are largely unknown. Collembola (Folsomia candida) has been used as a model organism in ecotoxicity and in this study we explored the transcriptional expression changes of Folsomia candida in response to PCP contamination. A total of 92 genes were significantly differentially expressed at all exposure time and majority of them were found to be down-regulated. In addition to the transcripts encoding cytochrome P450s and transferase enzymes, chitin-binding protein was also identified in the list of common differentially genes. Analyses of Gene Ontology (GO) annotation and enrichment revealed that cell cycle related transcripts were significantly induced by PCP, indicating it can stimulated the cell proliferation in springtail as reported in human breast cancer cells. We also observed enrichment of functional terms related to steroid receptor and particularly twenty significant differential expressed genes involved in Chitin metabolism in response to PCP exposure. Combined with the confirmation by qPCR, our results appears that the adverse effects on reproduction of springtails after exposure to PCP can be attributed to a chemical-induced delay in the molting cycle and molting associated genes may serve as possible biomarkers for toxicological effects. In general, analysis of changes in the gene expression profiles of springtails in response to PCP exposure is useful for obtaining information on endocrine disruptor exposure of soil invertebrate and may contribute to the classification and risk assessment of relative chemicals.

Project description:The experiment at three long-term agricultural experimental stations (namely the N, M and S sites) across northeast to southeast China was setup and operated by the Institute of Soil Science, Chinese Academy of Sciences. This experiment belongs to an integrated project (The Soil Reciprocal Transplant Experiment, SRTE) which serves as a platform for a number of studies evaluating climate and cropping effects on soil microbial diversity and its agro-ecosystem functioning. Soil transplant serves as a proxy to simulate climate change in realistic climate regimes. Here, we assessed the effects of soil type, soil transplant and landuse changes on soil microbial communities, which are key drivers in Earth’s biogeochemical cycles.

Project description:The present invention relates to methods for determining soil quality, and especially soil pollution, using the invertebrate soil organism Folsomia candida also designated as springtail. Specifically, the present invention relates to a method for determining soil quality comprising: contacting Folsomia Candida with a soil sample to be analysed during a time period of 1 to 5 days; isolating said soil contacted Folsomia Candida; extracting RNA from said isolated soil contacted Folsomia Candida; determing a gene expression profile based on said extracted RNA using microarray technology; comparing said gene expression profile with a reference gene expression profile; and determing soil quality based expression level differences between said gene expression profile and said control expression profile.
