Project description:Trauma-related disorders arise from inefficient fear extinction and have immeasurable social and economic costs. Here, we characterized mouse phenotypes that spontaneously show individual differences in adaptive or maladaptive fear extinction and, before the traumatic experience, we found that specific morphological, electrophysiological and transcriptomic patterns of fear matrix pyramidal neurons predispose to trauma-related disorders. Finally, by using an optogenetic approach we showed the possibility to rescue the inefficient fear extinction activating fear matrix infralimbic pyramidal neurons

Project description:Soil chemistry, metabarcoding, and metabolome analyses reveal that a sugarcane Dictyophora indusiata intercropping system enhances soil health by reducing soil nitrogen loss
Project description:Transcript profiles of H. annosum from different tissues and mycelium grown on different substrates and under different stresses were analyzed. The array probes were designed from gene models taken from the Joint Genome Institute (JGI, department of energy) H. irregulare genome sequence version 1. One aim of this study was to compare gene expression profiles of H. annosum during saprotrophic growth on topsoil from mineral soil, drained and undrained peatland.
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:Social anxiety disorder is characterized by a persistent and abnormal fear and avoidance of social situations, but available treatment options are rather unspecific. Using an established mouse social fear conditioning (SFC) paradigm, we profiled gene expression and chromatin alterations after acquisition and extinction of social fear within the septum, a brain region important for social fear and social behaviors. We validated coding and non-coding RNAs and found specific isoforms of the long non-coding RNA Meg3 to be regulated depending on the success of social fear extinction. In vivo knockdown of specific Meg3 isoforms in conditioned mice resulted in impaired social fear extinction, as revealed by lower social investigation levels at the end of the extinction training, accompanied with increased baseline activity of the PI3K/AKT signaling pathway. Using ATAC-Seq and CUT&RUN, we characterized alterations in chromatin level after social fear extinction and identified Auts2 and Dclk3 as potential targets of Meg3.
Project description:Soil microorganisms carry out decomposition of complex organic carbon molecules, such as chitin. High diversity of the soil microbiome and complexity of the soil habitat has posed a challenge to elucidate specific interactions between soil microorganisms. Here, we overcame this challenge by studying a model soil consortium (MSC-2) that is composed of 8 species. The MSC-2 isolates were originally obtained from the same soil that was enriched with chitin as a substrate. Our aim was to elucidate specific roles of the 8 member species during chitin metabolism in soil. The 8 species were added to sterile soil with chitin and incubated for 3 months. Multi-omics was used to understand how the community composition, transcript and protein expression and chitin-related metabolites shifted during the incubation period. The data clearly and consistently revealed a temporal shift during chitin decomposition and defined contributions by individual species. A Streptomyces species was a key player in early steps of chitin decomposition, followed by other members of MSC-2. These results illustrate how multi-omics applied to a defined consortium untangles complex interactions between soil microorganisms.
