Project description:Monitoring microbial communities can aid in understanding the state of these habitats. Environmental DNA (eDNA) techniques provide efficient and comprehensive monitoring by capturing broader diversity. Besides structural profiling, eDNA methods allow the study of functional profiles, encompassing the genes within the microbial community. In this study, three methodologies were compared for functional profiling of microbial communities in estuarine and coastal sites in the Bay of Biscay. The methodologies included inference from 16S metabarcoding data using Tax4Fun, GeoChip microarrays, and shotgun metagenomics.
Project description:The marine teleost intestine plays a vital role in whole body salt and water homeostasis. Marine fish must drink seawater in order to rehydrate, and processing of that seawater throughout the gastrointestinal tract allows for the extraction of water from this highly hyperosmotic source. Although the molecular mechanisms of this process have been the subject of much investigation, numerous questions remain. Here, Gulf toadfish (Opsanus beta) were acclimated to normal seawater (35 ppt) of hypersaline seawater (60 ppt) and changes in the anterior intestine, posterior intestine, and intestinal fluid proteomes were investigated using a shotgun proteomics approach employing isobaric TMT tags.
