FIG. 7.
Maximum parsimony phylogenetic tree (unrooted) of rickettsial small heat shock proteins. The scale bar indicates the number of amino acid changes within branch lengths. Bootstrap scores are indicated by numerals. GenBank accession numbers for the sequences used are as follows (in parentheses). Plasmid-encoded and PCR-amplified (marked with asterisk) plasmid-encoded Hsp sequences were from pRAM23 (GU322807), pRB* (GU180086), pRF (YP_247467 and YP_170678), pRHE* (GU180087), pRHO* (GU180088), pRIS (NZ_CM000771), pRM (YP_001967388 and YP_001967389), and pRPR (YP_002922008 and YP_002922009). Chromosome-encoded Hsp sequences were from R. africae (ZP_02336191), R. akari (YP_001493212), R. bellii (YP_538007), R. canadensis (YP_001492044), R. conorii (NP_360000), R. felis (YP_247020 and YP_247021), R. massiliae (YP_001499170), R. peacockii (YP_002916350), R. prowazekii (NP_220658), R. rickettsii (YP_001494483), R. sibirica (ZP_00142181), R. typhi (YP_067227), B. thailandensis (ZP_02384335), Francisella tularensis (YP_170678), L. pneumophila (YP_096204), T. adhaerens (XP_002118475), and W. pipientis (YP_001975380).
