Figure 3From: Extensive recombination events and horizontal gene transfer shaped the Legionella pneumophila genomesSchematic representation of P-type IV secretion systems (T4SSA) for conjugal DNA transfer of L. pneumophila. In green and orange, tra and trb genes respectively. L. long, Legionella longbeachae; P, Plasmid; C, Chromosome; ?, Protein of unknown function; A. tumefaciens, Agrobacterium tumefaciens; P. aeruginosa, Pseudomonas aeruginosa; t, transposase; pha, Phage repressor; Int, integrase; Pseudogenes are in discontinues squares; Yellow squares represent flanking repeats, with length and percentage of identity between repeats in parenthesis. tRNAs, their position in the genome is given in parenthesis.Back to article page
