Genome streamlining and chemical defense in a coral reef symbiosis
It is shown that the large patellazoles biosynthetic pathway is maintained, whereas the remainder of the genome is undergoing extensive streamlining to eliminate unneeded genes. Expand

The new species of Zanclea sango sp. nov. is described from Okinawajima Island, Ryukyu Archipelago, south-western Japan. The new hydrozoan species is associated with at least three scleractinianExpand
Multiple origins of the ascidian-Prochloron symbiosis: molecular phylogeny of photosymbiotic and non-symbiotic colonial ascidians inferred from 18S rDNA sequences.
The results strongly support the hypothesis that establishment of the ascidian-Prochloron symbiosis occurred independently in the Didemnidae lineage at least once in each of the genera that possess symbiotic species. Expand
Allorecognition in compound ascidians.
The fusibility locus of botryllids seems to be very similar to the MHC of vertebrates, considering that vertebrates evolved directly from ascidians, it is likely that the fusible locus is an ancestral form of the vertebrate MHC. Expand
Ascidian tunic cells: morphology and functional diversity of free cells outside the epidermis
In some ascidians, phagocytic cells are involved in other functions, such as pigmentation, intracellular photosymbiosis, and bioluminescence, suggesting that tunic cells have a high potential to diversify and evolve a wide variety of cellular functions. Expand
Complete nucleotide sequences of mitochondrial genomes of two solitary entoprocts, Loxocorone allax and Loxosomella aloxiata: implications for lophotrochozoan phylogeny.
Molecular phylogenetic analyses based on the sequences of mt protein-coding genes suggested a possible close relationship between Entoprocta and Phoronida, and a close relationship among Brachiopoda, AnnelIDA, and Echiura. Expand
Domination and disappearance of the black sponge: a quarter century after the initial Terpios outbreak in southern Japan.
Preliminary results suggest that T. hoshinota outbreaks, although very destructive, may be sporadic in nature, and not always an irreversible“climax” for affected reefs. Expand
Establishment of the photosymbiosis in the early ontogeny of three giant clams
The appearance of the lined zooxanthellae in the mantle of juvenile clams as the first sign of the establishment of symbiosis is designated, suggesting that filter-feeding also contributes to giant clam nutrition. Expand
Colonial Allorecognition, Hemolytic Rejection, and Viviparity in Botryllid Ascidians

In viviparous botryllids, colonial contact at artificially cut surfaces always results in colonial fusion and establishment of a common vascular network even between allogeneic colonies in which the growing-edge contact results in rejection, suggesting the limited distribution of allorecognition sites would be a solution to the embryo–parent histoincompatibility in v Viviparity.

Host specificity and phylogeography of the prochlorophyte Prochloron sp., an obligate symbiont in didemnid ascidians.
The genetic diversity of the genus Prochloron is investigated by constructing a phylogenetic tree based on the 16S rRNA gene sequences of 27 isolates from 11 species of didemnid ascidians collected from Japan, Australia and the USA, and implications for the evolutionary relationship of prochlorophytes, cyanobacteria and chloroplasts are discussed.
