A plot of $\overline{GC{B}_{Eff}}$-scores versus the number of tRNA genes and the minimum generation time for microbial species. Panel A: For 388 microbial species constituting the set MG_CUB the number of tRNA genes and the $\overline{GC{B}_{Eff}}$-score was determined as described and plotted. A Spearman rank correlation confirms the statistically significant correlation of these two values (r_s= 0.71, p < 0.001). Panel B: The minimum generation time for 113 species of MG_CUB (as listed in [13]) was plotted versus the $\overline{GC{B}_{Eff}}$-score. A Spearman rank correlation confirms the statistically significant correlation of these two values (r_s= -0.75, p < 0.001).
