The Eukaryotic Promoter Database is an annotated non-redundant collection of eukaryotic POL II promoters, for which the transcription start site has been determined experimentally. Access to promoter sequences is provided by pointers to positions in nucleotide sequence entries. The annotation part of an entry includes description of the initiation site mapping data, cross-references to other databases, and bibliographic references. EPD is structured in a way that facilitates dynamic extraction of biologically meaningful promoter subsets for comparative sequence analysis. (...) A eukaryotic promoter is defined as a DNA sequence around a transcription initiation site. The position reference to the initiation site is therefore the central part of a promoter entry. ...

Based on the mapping of the human genome and the development of information databases, a broad description of genes transcribed in blood cells is now known. Hembase was developed to provide worldwide access to those genetic-based studies performed by scientists in the Molecular Biology and Genetics Section, Molecular Medicine Branch, Division of Intramural Research, National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK). This project represents the shared goal of several individuals and groups (credits) interested in disseminating genomic information on the World Wide Web. ... [Information of the supplier]
Metazome is a database and graphical user interface enabling comparative genomic studies within the Metazoa. As of version 1.1, the database houses eleven sequenced animal genomes and is constantly growing as new genomes become available. Each gene has been annotated with PFAM, KOG, and PANTHER assignments, and publicly available annotations from RefSeq, SwissProt, Ensembl, and JGI are hyper-linked and searchable. For comparative studies, various clustering methods have been applied to construct orthologous groups of genes that represent the modern descendents of ancestral gene sets at key phylogenetic nodes, including the ancestral tetrapod and vertebrate. These clusterings allow easy access to clade specific orthology/paralogy relationships as well as clade specific genes and gene expansions. Position specific profiles will be made available shortly and gene phylogenetic trees are available now for each cluster to enable deeper comparative studies. ... [Information of the supplier]
The MicrobesOnline genome database contains over 300 prokaryotic genomes. All genomes are automatically analyzed through the VIMSS genome pipeline. We use publicly available sequence analysis tools and databases to search for homologs (NCBI BLAST, SwissProt, COG) and protein domains (InterPro), to assign gene ontologies (Gene Ontology Consortium) and EC numbers and to map the metabolic pathways (KEGG). We then link the orthology relationships between genes, predict operon structures and regulon networks. Most of the genomes are downloaded from NCBI and genes are parsed from GenBank files. When an incomplete genome is directly downloaded from a sequencing center, we predict protein coding genes using CRITICA and Glimmer, tRNA genes using tRNAscan and other RNA genes by BLASTn. All of the info in the VIMSS genome database is freely available on our website. ... [Information of the supplier]
The DNA amount in the unreplicated gametic nucleus of an organism is referred to as its C-value, irrespective of the ploidy level of the taxon. The Plant DNA C-values Database currently contains data for 3927 different Embryophyte plant species. It combines data from the Angiosperm DNA C-values Database (release 4.0, Jan. 2003), the Pteridophyte DNA C-values Database (release 2.0, Jan. 2003 ) together with the Gymnosperm DNA C-values Database (release 2.0, Jan. 2003) and the Bryophyte DNA C-values Database (release 1.1, Jan. 2003). ...

Das Consortium for the Barcode of Life (CBOL) ist eine internationale Initiative, die sich der Entwicklung des DNA Barcoding als eines umfassenden Standards in der Taxonomie widmet. CBOL hat mehr als 130 Mitgliedsorganisationen aus 40 Ländern. DNA Barcoding ist eine Technik, die kurze Gensequenzen aus einer standardisierten Region des Genoms als diagnostischen “Biomarker” für Arten benutzt. Verschiedene Arten haben unterschiedliche DNA-Barcodes; deshalb ist es möglich, Barcodes zu benutzen um: (1) Belegexemplare zu bestimmen, (2) möglicherweise neue Arten zu entdecken, (3) eine effektivere Taxonomie im Dienst von Wissenschaft und Gesellschaft zu ermöglichen. ...
