Echinoids are a major group of marine invertebrates with a long fossil record. If you know nothing about the group the obvious place to start is at the Introduction. Here you will find some basic facts about how echinoids live, feed and reproduce. Information presented here is very non-technical and is designed for the casual visitor with no biological training. The section entitled Morphology and morphological terms will be most useful to the serious amateur, undergraduate or those just beginning to get into the scientific literature who need some guidance with the formidable array of technical terms. Here you will find illustrations of the more commonly employed descriptive terms applied to echinoids. The primary purpose of the site, however, is to provide a taxonomic resource for the scientific community in which the genera and higher taxa of echinoid can be simply and rapidly identified. There are currently over 1500 pages of detailed information about echinoid taxa. Here no holds are barred and technical terms abound. A reasonable grasp of echinoid morphology is assumed and these pages will be of most use to professional scientists and advanced researchers. For each genus information is given about the type species, the key diagnostic characters, its stratigraphical and geographical distribution, species currently assigned with confidence (not by any means exhaustive), and remarks about recent scientific publications dealing with this taxon. Wherever possible high-quality images are provided of specimens in oral, aboral and lateral views. ... [Information of the supplier]
This web site is the home for genomic information on echinoderms. It either hosts or will soon host sequence and annotation data for species from all of the eleutherozoan echinoderms (sea urchins, sea stars, brittle stars and sea cucumbers). The primary source of sequence data is the ongoing sequencing efforts from Baylor College of Medicine, Human Genome Sequencing Center. Other sources include smaller sequencing projects from individual laboratories. We try to limit as our data sources as much as possible to those archived at Genbank. The information system residing here attempts to provide up-to-date information on genomes, genes and annotations for the use of the experimental scientists. It is our policy to post new sequence information in a timely way as well as insuring the primary datasets we use are archived at Genbank and other public data sites. ...

Completed in 2003, the Human Genome Project (HGP) was a 13-year project coordinated by the U.S. Department of Energy and the National Institutes of Health. During the early years of the HGP, the Wellcome Trust (U.K.) became a major partner; additional contributions came from Japan, France, Germany, China, and others. See our history page for more information. Project goals were to identify all the approximately 20,000-25,000 genes in human DNA, determine the sequences of the 3 billion chemical base pairs that make up human DNA, store this information in databases, improve tools for data analysis, transfer related technologies to the private sector, and address the ethical, legal, and social issues (ELSI) that may arise from the project. Though the HGP is finished, analyses of the data will continue for many years. Follow this ongoing research on our Progress page. ... [Information of the supplier]
DDBJ (DNA Data Bank of Japan) began DNA data bank activities in earnest in 1986 at the National Institute of Genetics (NIG). From the beginning, DDBJ has been functioning as one of the International DNA Databases, including EBI in Europe and NCBI in the USA as the two other members. Consequently, we have been collaborating with the two data banks through exchanging data and information on Internet and by regularly holding two meetings, the International DNA Data Banks Advisory Meeting and the International DNA Data Banks Collaborative Meeting. DDBJ is the sole DNA data bank in Japan, which is officially certified to collect DNA sequences from researchers and to issue the internationally recognized accession number to data submitters. We collect data mainly from Japanese researchers, but of course accept data and issue the accession number to researchers in any other countries. Since we exchange the collected data with EMBL/EBI and GenBank/NCBI on a daily basis, the three data banks share virtually the same data at any given time. We also provide worldwide many tools for data retrieval and analysis developed by at DDBJ and others. ... [Information of the supplier]
A database is a model of a piece of the world. RegulonDB in this sense is a model of the complex regulation of transcription initiation or regulatory network of the cell, on the one hand. On the other hand, it is also a model of the organization of the genes in transcription units, operons and simple and complex regulons. In this sense, RegulonDB is a computational model of mechanisms of transcriptional regulation. ... [Information of the supplier]
Cyanobacteria carry a complete set of genes for oxygenic photosynthesis, which is the most fundamental life process on the earth. This organism is also interesting from an evolutional viewpoint, for it was born in a very ancient age and has survived in various environments. Chloroplast is believed to have evolved from cyanobacterial ancestors which developed an endosymbiontic relationship with a eukaryotic host cell. CyanoBase provides an easy way of accessing the sequences and all-inclusive annotation data on the structures of the cyanobacterial genomes. ... [Information of the supplier]
Saccharomyces Genome Database is a scientific database of the molecular biology and genetics of the yeast Saccharomyces cerevisiae, which is commonly known as baker's or budding yeast. (...) SGD contains the sequences of yeast genes and proteins; descriptions and classifications of their biological roles, molecular functions, and subcellular localizations; links to literature information; links to functional genomics datasets; and tools for analysis and comparison of sequences. The SGD Home page is the main entry point for the database. SGD is aimed at scientists; collected information about yeast for the non-scientist can be found at the Yeast Virtual Library. SGD does not collect medical information, and SGD curators cannot answer health-related questions. ... [Information of the supplier]
FlyBase is a database of genetic and molecular data for Drosophila. FlyBase includes data on all species from the family Drosophilidae. [Information of the supplier]
Mouse Genome Informatics (MGI) provides integrated access to data on the genetics, genomics, and biology of the laboratory mouse. The projects contributing to this resource are: (1) Mouse Genome Database (MGD) Project; (2) Gene Expression Database (GXD) Project; (3) Mouse Tumor Biology (MTB) Database Project; (4) Gene Ontology (GO) Project. ...

ProDom is a comprehensive database of protein domain families generated from the global comparison of all available protein sequences. Recent improvements include the use of three-dimensional (3D) information from the SCOP database; a completely redesigned web interface; visualization of ProDom domains on 3D structures; coupling of ProDom analysis with the Geno3D homology modelling server; Bayesian inference of evolutionary scenarios for ProDom families. In addition, we have developed ProDom-SG, a ProDom-based server dedicated to the selection of candidate proteins for structural genomics. ... [Information of the supplier]
