PGLS analysis of GC contents and growth temperatures in core genes and accessory genes

	Core Genes			Accessory Genes
	Slope	P	PBH	Slope	P	PBH
GCp-Tmax	7.6 × 10−4	9.6 × 10− 4	0.002	9.0 × 10− 4	0.001	0.002
GCp-Topt	6.4 × 10−4	0.007	0.025	6.3 × 10−4	0.026	0.030
GC4-Tmax	0.002	6.3 × 10−4	0.002	0.002	0.003	0.003
GC4-Topt	0.002	0.004	0.025	0.002	0.019	0.030

GC contents were the dependent variables, and growth temperatures were the independent variables. The results in this table were obtained using the Brownian motion model. Similar results obtained from three other models are deposited in Additional file 1: Tables S12-S14. P_BH, Benjamini-Hochberg adjusted P value. Please see Table 1 for the meanings of the other abbreviations
