Analysis of the recombination event in N. meningitidis strain 510602. Sequences of N. meningitidis strains 510602, 630501, and FAM18 were compared and analyzed using the GENECONV method (the sequence of 630501 was proposed as the acceptor). The x axis shows genome length (nucleotide numbers of the consensus sequence), and the y axis shows the negative log of the probability value (P-Val). The beginning and end of the fragment that underwent recombination are connected by a line to form an open rectangle, and the height of the open rectangle is proportional to the negative log of the P value. The purple open rectangles represent the recombination events between strains 630501 and 510602, the yellow ones represent the events between strains 630501 and FAM18, and the green ones represent the events between strains 510602 and FAM18. The dashed lines represent the P value cutoffs.
