Open AccessPhylogenetic comparisons reveal mosaic histories of larval and adult shell matrix protein deployment in pteriomorph bivalves
Molluscan shells are organo-mineral composites, in which the dominant calcium carbonate is intimately associated with an organic matrix comprised mainly of proteins and polysaccharides. However, whether the va...

Open AccessFunctional shell matrix proteins tentatively identified by asymmetric snail shell morphology
Molluscan shell matrix proteins (SMPs) are essential in biomineralization. Here, we identify potentially important SMPs by exploiting the asymmetric shell growth in snail, Lymnaea stagnalis. Asymmetric shells req...

Open AccessThe habu genome reveals accelerated evolution of venom protein genes
Evolution of novel traits is a challenging subject in biological research. Several snake lineages developed elaborate venom systems to deliver complex protein mixtures for prey capture. To understand mechanism...

Open AccessTwo divergent Symbiodinium genomes reveal conservation of a gene cluster for sunscreen biosynthesis and recently lost genes
The marine dinoflagellate, Symbiodinium, is a well-known photosynthetic partner for coral and other diverse, non-photosynthetic hosts in subtropical and tropical shallows, where it comprises an essential componen...

Skeletal Organic Matrices in Molluscs: Origin, Evolution, Diagenesis
The mollusc shell comprises a small amount of organic macromolecules, mostly proteins and polysaccharides, which, all together, constitute the skeletal organic matrix (SOM). In the recent years, the study of t...

Molluscan Genomics: Implications for Biology and Aquaculture
As a result of advances in DNA sequencing technology, molluscan genome research, which initially lagged behind that of many other animal groups, has recently seen a rapid succession of decoded genomes. Since m...

Open AccessBivalve-specific gene expansion in the pearl oyster genome: implications of adaptation to a sessile lifestyle
Bivalve molluscs have flourished in marine environments, and many species constitute important aquatic resources. Recently, whole genome sequences from two bivalves, the pearl oyster, Pinctada fucata, and the Pac...

Open AccessThe Lingula genome provides insights into brachiopod evolution and the origin of phosphate biomineralization
The evolutionary origins of lingulid brachiopods and their calcium phosphate shells have been obscure. Here we decode the 425-Mb genome of Lingula anatina to gain insights into brachiopod evolution. Comprehensive...

Dynamic light scattering study of the curing mechanisms of novolac-type phenolic resins
The curing behavior of a novolac resin (NV) cured with hexamethylenetetramine (HMTA), as well as the influence of an excess amount of HMTA on the curing reaction, were investigated by dynamic light scattering ...

Expression patterns of engrailed and dpp in the gastropod Lymnaea stagnalis
We isolated the full-length cDNAs of engrailed and dpp-BMP2/4 orthologues from the pond snail Lymnaea stagnalis and examined their expression patterns during development by the whole mount in situ hybridization. ...

Biphasic and Dually Coordinated Expression of the Genes Encoding Major Shell Matrix Proteins in the Pearl Oyster Pinctada fucata
Regional expression patterns of shell matrix protein genes of Pinctada fucata were investigated using real-time quantitative polymerase chain reaction (PCR) and in situ hybridization. Six shell matrix proteins ex...
