Identification of two carbonic anhydrases in the mantle of the European Abalone Haliotis tuberculata (Gastropoda, Haliotidae): phylogenetic implications.
TLDR
Using the European abalone Haliotis tuberculata, a key model gastropod in biomineralization studies, two CAs are identified and characterized that are specific of the shell-forming mantle tissue and analyzed in a phylogenetic context.
Biomineralization markers during early shell formation in the European abalone Haliotis tuberculata, Linnaeus
TLDR
A strong increase in the level of calcitonin gene-related molecules was measured in post-larvae, suggesting that endocrine control takes place after metamorphosis, and correlate physiologic mechanisms with early steps of abalone shell formation.
Expression of biotransformation and oxidative stress genes in the giant freshwater prawn Macrobrachium rosenbergii exposed to chlordecone
TLDR
This gene expression study of selected genes should be further strengthened by proteomic analyses and enzymatic activity assays to confirm the response of these biomarkers of stress in crustaceans and to give new insights into the mechanism of toxicity by chlordecone.
Cloning and Use of a Coral 36B4 Gene to Study the Differential Expression of Coral Genes Between Light and Dark Conditions
TLDR
Results show that both photosynthetic genes are enhanced during the light when standardized against 36B4 and β-actin, whereas the two genes encoding proteins involved in calcium transport are not differentially expressed between light and dark conditions.
Two different and functional nuclear rDNA genes in the abalone Haliotis tuberculata: tissue differential expression
TLDR
A phylogenetic analysis makes a clear separation between type I and type II ITS1 sequences and supports grouping H. coccinea and H. marmorata together and proposes a general structure of the ITS1 transcript, with four major helices for the two types.
Expression of biomineralisation genes in tissues and cultured cells of the abalone Haliotistuberculata
TLDR
Primary cell cultures demonstrated that the three biomineralisation genes recently identified in the abalone Haliotis tuberculata were being expressed in abalone tissues, with expression highest in the mantle and much lower in the hemocytes and the gills.
Coral photosymbiosis: Linking phylogenetic identity to single cell metabolic activity in mixed symbiont populations
TLDR
A SIMS-ISH method combining nanoscale secondary ion mass spectrometry (NanoSIMS) and in situ hybridization (ISH) for the simultaneous in situ identification of Symbiodinium genotype, and visualization of symbiont-host metabolic exchange at the level of individual cell is developed.
