The germline definition in metazoans was first based on few bilaterian models. As a result, gene function interpretations were often phenotypes observed those models and led to the of set genes, considered as specific germline, named "germline core". However, some these genes shown also be involved somatic stem cells, thus leading notion multipotency program (GMP). Because Porifera Ctenophora are currently best candidates sister-group all other animals, comparative analysis contents...
Abstract Uncoupling protein 2 (UCP2) is suggested to be a regulator of reactive oxygen species production in mitochondria. We performed detailed study brain injury, including regional and cellular distribution UCP2 mRNA, as well measures oxidative stress markers following permanent middle cerebral artery occlusion knockout (KO) wild‐type (WT) mice. Three days post ischemia, there was massive induction mRNA confined microglia the peri‐infarct area WT KO mice were less sensitive ischemia...
The question of species survival and evolution in heterogeneous environments has long been a subject for study. Indeed, it is often difficult to identify the molecular basis adaptation contrasted environments, nongenetic effects increase difficulty disentangle fixed effects, such as genetic adaptation, from variable individual phenotypic plasticity, adaptation. Nevertheless, this also great importance understanding context climate change. red coral (Corallium rubrum) lives Mediterranean Sea,...
Ecosystems worldwide are suffering from climate change. Coral reef ecosystems globally threatened by increasing sea surface temperatures. However, gene expression plasticity provides the potential for organisms to respond rapidly and effectively environmental changes, would be favored in variable environments. In this study, we investigated thermal stress response Pocillopora coral colonies two contrasting environments exposing them heat stress. We compared physiological state, bacterial...
Passive acoustic monitoring can offer insights into the state of coral reef ecosystems at low-costs and over extended temporal periods. Comparison whole soundscape properties rapidly deliver broad from data, in contrast to detailed but time-consuming analysis individual bioacoustic events. However, a lack effective automated for data has impeded progress this field. Here, we show that machine learning (ML) be used unlock greater soundscapes. We showcase on diverse set tasks using three...
Premise of the Study Simple sequence repeat ( SSR ) or microsatellite markers have been used in a broad range studies mostly scoring alleles on basis amplicon size as proxy for number units an motif. However, additional sources variation within flanking regions largely remained undetected. Methods In this study, we implemented next‐generation sequencing–based genotyping approach newly characterized set 18 nuclear carob tree, Ceratonia siliqua . Our aim was to evaluate effect three different...
The mitochondrial carrier family transports a variety of metabolites across the inner membrane. We identified and cloned new member this family, KMCP1 (kidney protein-1), that is highly homologous to previously protein BMCP1 (brain protein-1). Western blotting in situ experiments showed expressed predominantly within kidney cortex proximal distal tubules. was increased during fasting regenerative phase glycerol-induced renal failure. show both situations are associated with transiently...
Sexual reproduction is widespread among eukaryotes, and the sex-determining processes vary greatly species. While genetic sex determination (GSD) has been intensively described in bilaterian species, no example yet recorded non-bilaterians. However, quasi-ubiquitous repartition of GSD multicellular species suggests that similar evolutionary forces can promote this system, these could occur also Studying across range Metazoan diversity indeed important to understand better evolution mechanism...

The study of the interplay between speciation and hybridization is primary importance in evolutionary biology. Octocorals are ecologically important species whose shallow phylogenetic relationships often remain to be studied. In Mediterranean Sea, three congeneric octocorals can observed sympatry: Eunicella verrucosa, cavolini singularis . They display morphological differences E. hosts photosynthetic Symbiodinium , contrary two other species. Two nuclear sequence markers were used gene flow...
French Polynesia is experiencing increasing coral bleaching events in shallow waters triggered by thermal anomalies and marine heatwaves linked to climate change, a trend that replicated worldwide. As sea surface are assumed lessen with depth, mesophotic deep reefs have been hypothesized act as refuges from anthropogenic natural disturbances, the ‘deep reef refugia hypothesis’ (DRRH). However, evidence supporting DRRH either inconclusive or conflicting. We address this investigating four...
Genomic data allow an in-depth and renewed study of local adaptation. The red coral (Corallium rubrum, Cnidaria) is a highly genetically structured species promising model for the adaptive processes along environmental gradient. Here, we used RAD-Sequencing in order to vertical genetic structure this search signals adaptation depth thermal regime coral. Previous studies have shown different thermotolerance levels according which could correspond or differences. We designed sampling scheme...
Abstract Reticulated evolution -i.e. secondary introgression / admixture between sister taxa-is increasingly recognized as playing a key role in structuring infra-specific genetic variation and revealing cryptic connectivity patterns. When zones coincide with ecological transitions, the patterns often follow environmental variations better than distance clines may easily be confounded local adaptation signatures. The Kerguelen mussels is an ideal system to investigate potential of enhancing...

Global change scenarios in the Mediterranean basin predict a precipitation reduction within coming hundred years. Therefore, increased drought will affect forests both terms of adaptive ecology and ecosystemic services. However, how vegetation might adapt to is poorly understood. In this report, four years climate was simulated by excluding 35% above downy oak forest. RNASeq data allowed us assemble genome-guided transcriptome. This led identification differentially expressed features, which...
ABSTRACT It is widely accepted that populations of terrestrial predators sometimes contain “problem individuals” repeatedly attack humans, yet this phenomenon has never been demonstrated in sharks. Here, we present photographic and genetic evidence individuals tiger Galeocerdo cuvier oceanic whitetip Carcharhinus longimanus sharks (1) atypical behavior compared to the rest population, (2) engaged repeated agonistic directed toward (3) bit, or attempted bite humans probable foraging attempts....
