The thermal limit for metazoan life, expected to be around 50°C, has been debated since the discovery of Pompeii worm Alvinella pompejana, which colonizes black smoker chimney walls at deep-sea vents. While indirect evidence predicts body temperatures lower than repeated in situ temperature measurements depict an animal thriving 60°C and more. This controversy was remain as long this species escaped vivo investigations, due irremediable mortalities upon non-isobaric sampling. Here we report...
The hard clam Mercenaria mercenaria is a major marine resource along the Atlantic coasts of North America and has been introduced to other continents for restoration or aquaculture activities. Significant mortality events have reported in species throughout its native range as result diseases (microbial infections, leukemia) acute environmental stress. In this context, characterization genome can provide highly needed resources enable basic (e.g., oncogenesis cancer transmission, adaptation...
The effects of pesticide contamination on the metabolism marine molluscs are poorly documented. We investigated response a bivalve, Pacific oyster, Crassostrea gigas , using suppression subtractive hybridization method to identify up‐ and down‐regulated genes after 30‐day exposure period herbicides (a cocktail atrazine, diuron isoproturon, single herbicide glyphosate). A total 137 unique differentially expressed gene sequences was identified, as well their associated physiological process....
Abstract The European flat oyster ( Ostrea edulis L.) is a bivalve naturally distributed across Europe, which was an integral part of human diets for centuries, until anthropogenic activities and disease outbreaks severely reduced wild populations. Despite growing interest in genetic applications to support population management aquaculture, reference genome this species lacking date. Here, we report chromosome‐level assembly annotation the Flat genome, generated using Oxford Nanopore,...
Three species of mangrove oysters, Crassostrea rhizophorae, C. brasiliana, and gasar, have been described along the Atlantic shores South America Africa. Because distribution these molluscs is great biological commercial interest, their taxonomy deserve further clarification. Therefore, 15 populations were sampled from both continents. Their 16S mitochondrial polymorphism was studied by sequencing PCR-RFLP analysis. Two haplotypes identified. Haplotype a only one observed in Africa, but it...
Hydrothermal vents and cold seeps represent oases of life in the deep-sea environment, but are also characterized by challenging physical chemical conditions. The effect temperature fluctuations on vent organisms their habitat has not been well explored, particular at a molecular level, most gene expression studies being conducted coastal marine species. In order to better understand response hydrothermal different regimes, differentially expressed genes (obtained subtractive suppression...
Taking advantage of the massive genome sequencing effort made on thermophilic prokaryotes, thermal adaptation has been extensively studied by analysing amino acid replacements and codon usage in these unicellular organisms. In most cases, to thermophily is associated with greater residue hydrophobicity more charged residues. Both characteristics are positively correlated optimal growth temperature prokaryotes. contrast, little information collected molecular 'adaptive' strategy eukaryotes....
The European flat oyster (
The flat oyster Ostrea edulis is the native European species, with a distribution extending from Norwegian Sea in north to Morocco south, and eastward through Mediterranean Black (OSPAR, 2009). Since 19th century, industry has been decline, primarily due habitat destruction, over-exploitation, irregular recruitment, emergence of parasites Marteilia refringens Bonamia ostreae 1970s. O. species both economic ecological significance, efforts protect restore it have become extensive response...
Hydrothermal vent mussels belonging to the genus Bathymodiolus are distributed worldwide and dominate communities at shallow Atlantic hydrothermal sites. While organisms inhabiting coastal ecosystems subjected predictable oscillations of physical chemical variables owing tidal cycles, sustain pronounced temperature changes over short periods time, correlated alternation oxic/anoxic phases. In this context, we focused on short-term adaptive response change a molecular level. The mRNA...
Abstract Background Alvinella pompejana is a representative of Annelids, key phylum for evo-devo studies that still poorly studied at the sequence level. A. inhabits deep-sea hydrothermal vents and currently known as one most thermotolerant Eukaryotes in marine environments, withstanding largest chemical thermal ranges (from 5 to 105°C). This tube-dwelling worm forms dense colonies on surface chimneys can withstand long periods hypo/anoxia phases exposure hydrogen sulphides. specifically...
SUMMARYPesticide run-off into the ocean represents a potential threat to marine organisms, especially bivalves living in coastal environments. However, little is known about effects of environmentally relevant concentrations pesticides at individual level. In this study, suppression subtractive hybridisation technique was used discover main physiological function affected by cocktail three (lindane, metolachlor and carbofuran) Pacific oyster Crassostrea gigas. Two populations exposed...
