In the N2-fixing bacterium Rhizobium leguminosarum, mutations in a homologue of tonB (tonB(Rl)) block the import of vicibactin and haem as iron sources in free-living bacteria. TonB(Rl) mutants were normal for growth with ferric dicitrate and slightly reduced for growth with haemoglobin as sole i...
