From: A positive correlation between GC content and growth temperature in prokaryotes
Positive correlations between the sudden changes in GC content and growth temperature of bacteria. Following Mahajan and Agasheand [3], the evolutionary jumps of GCw (whole-genome GC content) and Topt (optimal growth temperature) in the bacterial phylogenetic tree were detected using the Lévy jumps model [57]. A the magnitude of the GCw jumps are significantly correlated with the accompanied changes in Topt (Spearman′s rank correlation, 2-tailed, n = 108, rho = 0.209, P = 0.030). B the magnitude of the Topt jumps is significantly correlated with the accompanying change in GCw (Spearman’s rank correlation, 2-tailed, n = 86, rho = 0.280, P = 0.009).
