Log-log plot of the total number of annotated proteins in genomes submitted to GenBank as a function of genome size. Based on data from NCBI genome reports.. Bacteria possess a compact genome architecture distinct from eukaryotes in two important ways: bacteria show a strong correlation between genome size and number of functional genes in a genome, and those genes are structured into operons.
This list of sequenced eubacterial genomes contains most of the eubacteria known to have publicly available complete genome sequences.Most of these sequences have been placed in the International Nucleotide Sequence Database Collaboration, a public database which can be searched [1] on the web.
All of the genome annotations in BacMap were generated through the BASys genome annotation system. [3] BASys is a widely used microbial annotation infrastructure that performs comprehensive bioniformatic analyses on raw (or labeled) bacterial genome sequence data.
BASys (Bacterial Annotation System) is a freely available web server that can be used to perform automated, comprehensive annotation of bacterial genomes. [2] With the advent of next generation DNA sequencing it is now possible to sequence the complete genome of a bacterium (typically ~4 million bases) within a single day.
The first bacterial genome to be sequenced was that of Haemophilus influenzae, completed by a team at The Institute for Genomic Research in 1995. A few months later, the first eukaryotic genome was completed, with sequences of the 16 chromosomes of budding yeast Saccharomyces cerevisiae published as the result of a European-led effort begun in ...
To overcome this uncertainty, modern bacterial classification emphasises molecular systematics, using genetic techniques such as guanine cytosine ratio determination, genome-genome hybridisation, as well as sequencing genes that have not undergone extensive lateral gene transfer, such as the rRNA gene.

The J. Craig Venter Institute filed patents for the Mycoplasma laboratorium genome (the "minimal bacterial genome") in the U.S. and internationally in 2006. [b 15] [b 16] [a 22] The ETC group, a Canadian bioethics group, protested on the grounds that the patent was too broad in scope. [b 17]
Saccharomyces cerevisiae was the first eukaryotic organism to have its complete genome sequence determined.. This list of "sequenced" eukaryotic genomes contains all the eukaryotes known to have publicly available complete nuclear and organelle genome sequences that have been sequenced, assembled, annotated and published; draft genomes are not included, nor are organelle-only sequences.
