The Whole-Genome and Transcriptome of the Manila Clam (Ruditapes philippinarum)

The manila clam, Ruditapes philippinarum, is an important bivalve species in worldwide aquaculture including Korea. The aquaculture production of R. philippinarum is under threat from diverse environmental factors including viruses, microorganisms, parasites, and water conditions with subsequently declining production. In spite of its importance as a marine resource, the reference genome of R. philippinarum for … Continue reading The Whole-Genome and Transcriptome of the Manila Clam (Ruditapes philippinarum)

Metabolomic applications in marine mollusc development and aquaculture

Metabolomics is a rapidly emerging discipline within functional genomics to better understand biochemical phenotypes across a range of biological systems. The approach has many demonstrated applications in aquatic biology, but has not yet been applied to study early lifestages of marine molluscs. This Thesis evaluates metabolomics as an approach to characterise early lifestage phenotypes of … Continue reading Metabolomic applications in marine mollusc development and aquaculture

Comparative and evolutionary analysis of an adapter molecule MyD88 in invertebrate metazoans

The myeloid differentiation factor 88 (MyD88) is an essential adapter in Toll-like receptor (TLR) signalling pathways, with TLR the first pattern-recognition receptor (PRR) that was discovered in Drosophila. In the present study, a MyD88 gene was identified and characterized from a commercially important shellfish, Scapharca subcrenata, including a DEATH domain and TIR domain conserved within … Continue reading Comparative and evolutionary analysis of an adapter molecule MyD88 in invertebrate metazoans

Comparative 16SrDNA Gene-Based Microbiota Profiles of the Pacific Oyster (Crassostrea gigas) and the Mediterranean Mussel (Mytilus galloprovincialis) from a Shellfish Farm (Ligurian Sea, Italy)

The pacific oyster Crassostrea gigas and the Mediterranean mussel Mytilus galloprovincialis are two widely farmed bivalve species which show contrasting behaviour in relation to microbial diseases, with C. gigas being more susceptible and M. galloprovincialis being generally resistant. In a recent study, we showed that different susceptibility to infection exhibited by these two bivalve species … Continue reading Comparative 16SrDNA Gene-Based Microbiota Profiles of the Pacific Oyster (Crassostrea gigas) and the Mediterranean Mussel (Mytilus galloprovincialis) from a Shellfish Farm (Ligurian Sea, Italy)

Temporal stability in levels of genetic variation of the invasive bivalve Isognomon bicolor (C. B. Adams, 1845) (Bivalvia, Isognomonidae) at Praia de Itaipu, Niterói city, Rio de Janeiro state, southeastern Brazil

We investigated the evolutionary genetics of the marine bioinvader bivalve Isognomon bicolor (C. B. Adams, 1845) by the allozyme electrophoresis method. For that, we collected individuals in 2005, 2009, and 2013 at Praia de Itaipu (Niterói city, Rio de Janeiro state, southeastern Brazil). Seven allozymic systems were interpreted as eleven loci. The observed heterozygosity ranged … Continue reading Temporal stability in levels of genetic variation of the invasive bivalve Isognomon bicolor (C. B. Adams, 1845) (Bivalvia, Isognomonidae) at Praia de Itaipu, Niterói city, Rio de Janeiro state, southeastern Brazil

Macrophages in invertebrates: from insects and crustaceans to marine bivalves

Macrophages are critical components of the antimicrobial response. The recent explosion of knowledge on the evolutionary, genetic, and biochemical aspects of the interaction between macrophages and microbes has renewed scientific interest in macrophages. The conservation of immune components or mechanisms between organisms during the evolutionary process allows us to elucidate antimicrobial mechanisms or discover new … Continue reading Macrophages in invertebrates: from insects and crustaceans to marine bivalves

Environmental conditions increase growth rates and mortality of zebra mussels (Dreissena polymorpha) along the southern invasion front in North America

Environmental conditions found along an invasion front can mediate spread dynamics of an invasive species. Conditions that affect survival and individual growth rates of founder propagules and the first young-of-year generation can have a profound effect on establishment dynamics. Responses of younger, more sensitive individuals to these novel conditions, in part, determine establishment success. The … Continue reading Environmental conditions increase growth rates and mortality of zebra mussels (Dreissena polymorpha) along the southern invasion front in North America
