The Genomics platform (PF1) undertakes the sequencing of whole microbial genomes in collaboration with several IP teams in addition to smaller projects analysing genomic regions, sets of cDNAs libraries and PCR products. PF1 performs the sequencing then, transfers, the sequences to the partner who carries out the analysis steps. However, in most cases of genome sequencing projects, PF1 conducts the entire process internally and passes on the assembled, polished sequence for analysis. PF1 aims to group state-of-the-art equipment and corresponding technical and methodological process to provide for the needs of the research teams of the Institut Pasteur and its International Network in the field of sequencing projects. PF1 has a closely collaboration with the « Biological Software and Databases » Group (LBD) for installation of biological softwares and developing bioinformatic programs.
The major projects which have been undertaken concerns an epidemic strain of Helicobacter pylori associated with Mucosa Associated Lymphoid Tissue (MALT); the saprophyte Leptospira biflexa which is a model bacteria of spirochetes; an epidemic strain of streptococcal pathogen Streptococcus pneumonia and a strain of Streptococcus macedonicus.
M. aeruginosa PCC 7806, is a cyanobacterium responsible for water spoliage and, during seasonal blue-green algal blooms, produces a neurotoxin. Its genome has been published as a draft of a scaffold contained one hundred of contigs.
A comparative genomics of Hemiascomycetous yeasts study has been investigated with a low coverage sequencing approach of 6 closely phylogenetic species.
Genomic analysis has also been performed with protozoan parasites of interest to human medicine. Allelic diversity and drug resistance of Plasmodium falciparum and Plasmodium vivax, agents of human malaria, have been studied. EST sequencing of clones from different libraries has also been done with Anopheles gambiae and Entamoeba histolytica.
The complete list of all these projects is available on the website of the platform.

Since july 2008 a next-generation sequencing technologies system, Illumina's Genome Analyser II-has been installed at Genopole. This equipment shared with the DNA micro-arrays Platform (PF2), is used for microbial genome resequencing projects.
Since july 2008, High Throughput Synthesis of Long Oligonucleotides Platform has been attached to PF1. Synthesize oligodeoxynucleotides modified in the 5' and/or 3' end by different fluorophores, quenchers (molecular beacons), by amino-alkyl groups or by modified bases through out the sequence is maintained.
Short RNA and siRNA sequences can be made too.
