An international consortium, including a team from the CEA/Genoscope, carried out the complete sequencing of the genome of a tomato variety using MinION, a portable sequencer developed by Oxford Nanopore.
Nanopore sequencing consists of passing a strand of DNA through a biological pore to identify the sequence of bases (A, C, G, T) that make up this DNA fragment. Thanks to recent improvements, this sequencing technology (brought to the market by Oxford Nanopore Technologies) now allows obtaining gigabases of data, while also enabling the reading of large fragments of DNA (several tens of kilobases). Previously, due to its reduced throughput, this sequencing technology was principally used to analyze microbial samples with genome sizes on the order of a few million bases.

CEA is a French government-funded technological research organisation in four main areas: low-carbon energies, defense and security, information technologies and health technologies. A prominent player in the European Research Area, it is involved in setting up collaborative projects with many partners around the world.
