NCBI offers a number of specialized BLAST pages for model organisms that allow queries ranging from MegaBlast searches for nearly exact nucleotide matches to tblastn protein queries of translated nucleotide databases. The databases for each organism differ, depending upon the availability of sequence data, however, the spectrum of nucleotide databases includes Whole Genome Shotgun traces, HTG sequences, ESTs, genome assemblies, and mRNA sequences from annotated genes. Protein databases comprised of the protein translations of annotated genes are also available for many organisms. Links to organism-specific BLAST pages are found within the “Genomic BLAST Pages” section of the main BLAST page. In addition to human, the organisms covered include mouse, rat, and microbes, Arabidopsis, puffer fish, rice, mosquito, zebrafish, and other eukaryotes.
