Project description:Blue mussel larvae were fed, in a first group, a balanced diet of essential fatty acids (EFAs) provided by a cocktail diet (COC) from three algal species. Larvae were cultured in three separate tanks from hatching, 0 day post-fertilization (DPF) until 42 DPF. Treated larvae were fed a deficient diet (Tiso) that contains low levels of arachidonic acid (AA) and eicosapentaenoic acid (EPA), two EFAs necessary for larval development, performance, and survival. The goal is to identify coordinated patterns of gene expression and understand their predictive function in relation to growth and mortality during early developmental stages of the blue mussel Mytilus edulis. In order to understand the mechanisms by which growth and survival drive an organism to the full range of its adaptation, we de novo assembled of the mussel transcriptome during early development using next-generation sequencing (NGS) technology, then designed customized microarrays targeting every developmental stage, which encompass major transitions in tissue organization of the fast-evolved blue mussel

Project description:This project is aiming to examine the molecular response of the blue mussel (Mytilus edulis) to increased air temperatures and reduced salinity under laboratory conditions. There are 5 treatment groups (n=5), with group A representing the control (salinity 23percent salinity and temperature 5 degree celsius), group B ( 23percent salinity 30 degree celsius), group C (23percent salinity 33 degree celsius), group D (15percent salinity 5 degree celsius), group E (15percent salinity 30 degree celsius), group F (15percent salinity33 degree celsius), group G (5percent salinity 5 degree celsius).

Project description:Background biology: Global warming has accelerated in recent decades, with the Arctic warming 2–3 times faster than the global average. As a result boreal species are expanding into the Arctic, at a pace reflecting environmental warming. Nevertheless, the poleward expansion of boreal marine species is restricted by their ability to tolerate low water temperatures, and in the case of intertidal species, sub-zero air temperatures during winter. In Greenland, however, the number of days with extreme sub-zero air temperatures has decreased by more than 50% since the 1950’s, suggesting that the low air temperature constraint is weakening. Although boreal intertidal species could potentially benefit from this warmer climate to establish populations in the Arctic, recent work has shown that local intertidal summer air temperatures in Greenland can exceed 36°C. This temperature is above the thermoregulatory capacity of many boreal intertidal species, including the highly abundant blue mussel Mytilus edulis. Therefore will further colonisation of M. edulis in Greenland be inhibited by the increasingly warm summer temperatures. Aim of experiment: Intertidal animals (Greenland blue mussel M. edulis) were sampled in situ on the first warm days of the year from the inner (warmer) and outer (cooler) regions of the Godthåbsfjorden around Nuuk (64°N) to examine the fjord temperature gradient effect. In addition, subtidal M. edulis were also collected and subjected to two acute temperature shocks of 22 and 32°C, which represented common and extreme summer air temperatures for intertidal habitats near Nuuk.

Project description:Mussels are a group of sessile and filter-feeding invertebrates, and are key structural elements of many marine and freshwater ecosystems. The mussel haemolymph is the first defense line to pathogen infection and inflammation with an innate immune response. Despite the importance of this body fluid in determining the physiological condition of the animal, little is known about the molecular mechanisms underlying the cellular and humoral responses. Proteomic characterization of this body fluid has been hampered by the scarce Mytilus sp genomic data available. To systematic characterize the marine mussel Mytilus edulis hemolymph proteome, we have applied a mass spectrometry (nanoLC-MS/MS) strategy integrating genomics and transcriptomics data for proteins identification. After sample analysis and first identification based on MS/MS data comparison, proteins with unknown functions were annotated with blast using public database (nrNCBI) information. Overall 654 haemolymph proteins were identified with high confidence. The gene ontology analysis revealed that the majority of haemolymph proteins participate in primary cellular metabolic processes: energy production and metabolism of biomolecules. Nevertheless it also revealed a protein complement whose functions could be related to oxidative stress defense, xenobiotic detoxification, drug metabolism and immune response.

Project description:Transcriptional profiling of the digestive gland tissue of female mussel Mytilus galloprovincialis exposed to copper along with a temperature gradient Background: Global warming is a major factor that may affect biological organization, especially in marine ecosystems and in coastal areas that are particularly subject to anthropogenic pollution. We evaluated the effects of simultaneous changes in temperature and copper concentrations on lysosomal membrane stability of the blue mussel Mytilus galloprovincialis (Lam.). Temperature and copper exerted additive effects on lysosomal membrane stability, exacerbating the toxic effects of metal cations present in non-physiological concentrations. Mussel lysosomal membrane stability was positively related toscope for growth, indicating possible effects of increasing temperature on mussel populations in metal-polluted areas. To clarify the molecular response to environmental stressors, we used a cDNA microarray with 1,700 sequences to measure the relative transcript abundances in the gills of mussels exposed to copper (40µg/L) and a temperature gradient (16°C, 20°C, and 24°C). In animals exposed only to heat stress, hierarchical clustering of the microarray data revealed three main clusters, which were largely dominated by down-regulation of translation-related differentially expressed genes, drastic up-regulation of folding protein-related genes, and genes involved in chitin metabolism. The response of mussels exposed to copper at 24° C was characterized by an opposite pattern of the genes involved in translation, most of which were up-regulated, as well asthe down-regulation of genes encoding heat shock proteins and microtubule-based movement proteins. Our data provide novel information on the transcriptomic modulations in mussels facing temperature increases and high copper concentrations; these data highlight the risk of marine life exposed to toxic chemicals in the presence of temperature increases due to climate change.
