reference taxon for studying metazoan origins. Like a living time capsule, they may allow us to infer the genome content and cell biology of the unicellular progenitors of Metazoa. For example, comparing choanoflagellate and metazoan genomes will reveal the minimal genetic toolkit of the first metazoan. Pilot studies of choanoflagellate expressed genes have already uncovered homologs of a remar...
متن کاملInvestigation of Oscillatoria spongeliae-dominated bacterial communities in four dictyoceratid sponges.
Certain species of marine sponges in the order Dictyoceratida harbor large populations of the cyanobacterial symbiont Oscillatoria spongeliae in the mesohyl (interior) of the sponge. We show that in four of these sponge species (Lamellodysidea herbacea, Lamellodysidea chlorea, Lendenfeldia chondrodes, and Phyllospongia papyracea) from Palau there is a consistent community of alpha-proteobacteri...
متن کاملPhylogeny and evolution of glass sponges (porifera, hexactinellida).
Reconstructing the phylogeny of sponges (Porifera) is one of the remaining challenges to resolve the metazoan Tree of Life and is a prerequisite for understanding early animal evolution. Molecular phylogenetic analyses for two of the three extant classes of the phylum, Demospongiae and Calcarea, are largely incongruent with traditional classifications, most likely because of a paucity of inform...
متن کاملSuper sponges.
The localisation of tumour deposits by a 131 1 labelled monoclonal antibody to carcinoembryonic antigen (CEA) has been evaluated in 24 patients with primary gastric, oesophageal and colorectal cancer and in 26 patients with clinically suspected recurrent gastric and colorectal cancer. Seventeen of 20 primary sites and 6/15 associated secondary sites were correctly identified by external scannin...
