| multiple src-related kinase genes, srk1-4, in the fresh water sponge spongilla lacustris. | in one of the simplest metazoan organisms, the sponge spongilla lacustris, at least four different src-related kinase genes (srk1-4) are expressed, all of which show a high degree of similarity to the c-src genes of vertebrates. whereas srk2 and srk3 are clearly unrelated at the nucleic acid level, srk1 and srk4 share identical sequences in the 5' parts of their cdnas. the cloning of several primer extension clones and genomic polymerase chain reaction experiments confirmed the hypothesis of an ... | 1992 | 1378585 |
| cellular src gene product detected in the freshwater sponge spongilla lacustris. | serum from rous sarcoma virus tumor-bearing rabbits immunoprecipitated from extracts of the freshwater sponge spongilla lacustris a tyrosine-specific protein kinase with characteristics similar to the chicken pp60c-src kinase activity. an immune competition assay confirmed the relationship between the protein from sponges and viral pp60v-src. | 1984 | 6330536 |
| heterologous expression of dsred2 in young sponges (porifera). | sponges (porifera) are currently considered to be the first branch off the urmetazoa, common ancestors of all multicellular animals or metazoa. research in the field of the developmental biology of sponges was restricted to morphological observations. nowadays, research is mainly concentrated on larval development, primarily dealing with tissue formation. already since 1907, methods for developing functional sponges from stem cells have been at hand. functional freshwater sponges can be grown fr ... | 2009 | 19598130 |
| permanent genetic resources added to molecular ecology resources database 1 december 2009-31 january 2010. | this article documents the addition of 220 microsatellite marker loci to the molecular ecology resources database. loci were developed for the following species: allanblackia floribunda, amblyraja radiata, bactrocera cucurbitae, brachycaudus helichrysi, calopogonium mucunoides, dissodactylus primitivus, elodea canadensis, ephydatia fluviatilis, galapaganus howdenae howdenae, hoplostethus atlanticus, ischnura elegans, larimichthys polyactis, opheodrys vernalis, pelteobagrus fulvidraco, phragmidiu ... | 2010 | 21565062 |

| mercury and chlorinated hydrocarbons in zoobenthos of lake päijänne, finland. | the average amounts of mercury, pcbs, and sigma ddt (primarily dde), found in macrozoobenthos, on the wet basis, in lake päijänne, finland, for the time period 1972-1974, were 79 ng/g, 29 ng/g, and 8 ng/g, respectively. lindane was found in negligible amounts in only 2% of the samples examined; aldrin was present in 10% of the samples; no dieldrin was detected. mercury and pcb concentrations varied regionally in the lake. pcb and sigma ddt concentrations were greater in the predatory bottom anim ... | 2002 | 120136 |
| characterization and phylogenetic analysis of a cdna encoding the fes/fer related, non-receptor protein-tyrosine kinase in the marine sponge sycon raphanus. | in search of ancient versions of phylogenetically conserved genes/proteins, which are typical for multicellular animals, we have decided to analyse marine sponges (porifera), the most ancient and most primitive metazoan organisms. we report here the complete nucleotide sequence of sycon raphanus cdna coding for a 879 aa long protein, which displays high overall similarity in primary structure and organization of domains with non-receptor tyrosine kinases (tks) from the fes/fer family. the encode ... | 1998 | 9714748 |
| clypeatula cooperensis gen. n., sp. n., a new freshwater sponge (porifera, spongillidae) from the rocky mountains of montana, usa. | a new genus and species of freshwater sponge, clypeatula cooperensis, collected from three lakes in the northern rocky mountains of montana, usa, are described. the sponge grows as a hard, disc-shaped encrustation on the undersides of rocks and logs. it lacks microscleres and has amphioxeal megascleres that often show a slight midregion bulb and are usually covered with short, conical spines except at their tips. the sponge is also non-gemmulating, overwintering in a regressed state in which cho ... | 2000 | 12194185 |
