Table 3 Codon-based test of positive selection for analysis between inmp sequences of ‘Ca. P. phoenicium’ strains

Model	Prob^a	Stat^b
Modified Nei-Gojobori Method (Proportion)	0.026	1.961
Modified Nei-Gojobori Method (Jukes-Cantor)	0.034	1.836
Pamilo-Bianchi-Li Method (Kimura 2-para)	0.015	2.191

^a The probability of rejecting the null hypothesis of strict-neutrality (d_N = d_S) in favor of the alternative hypothesis (d_N > d_S). Values of P less than 0.05 are considered significant at the 5 % level
^b The test statistic (d_N - d_S) is shown. d_S and d_N are the numbers of synonymous and nonsynonymous substitutions per site, respectively. The variance of the difference was computed using the bootstrap method (1000 replicates)
