The functions of the entire genome of the bacterium Sinorhizobium meliloti, a symbiont of legume plants, capable of transforming atmospheric nitrogen into forms of nitrogen assimilable by the plant, has been mapped. This is the result of a project coordinated by a young researcher of the Department of Biology, George diCenzo, a member of the team led by Alessio Mengoni and Marco Fondi, and published in the journal PLOS Genetics
