Circular map of the chromosome of K. pneumoniae Kp13 and related bacteria. The innermost ring represents the K. pneumoniae Kp13 chromosome used as reference and its coordinates. The second ring (in black) plots the G + C content of the reference, followed by its G + C skew (in purple/green). Red, cyan and green rings that follow depict BLASTN comparisons between the chromosomes of Kp13 and those of strains MGH 78578, NTUH-K2044 and 342, respectively. The outermost, interspaced rings (in orange) represent the localization of the predicted regions of genomic plasticity in the Kp13 chromosome, and the labels of each region follow the ones in Table 2.
