Evolution of the whole genome GC Content, core genes CDS sequences GC content, Genome Size, and Duplications of Core Genes in Fusarium. The species complexes are organized as presented in the collapsed tree, with the most ancestral clades positioned at the bottom of the graph. Lines connect the median values of the boxplots. Kruskal–Wallis rank sum test p < 2.2 × 10^-16. A Box plots illustrating the evolution of genome GC content. B Box plots demonstrate the evolution of core gene CDS sequences GC content, with analysis conducted on a subset of CDSs ranging between 4076 and 4480 per genome. C Box plots depicting the evolution of genome size. D Box plots displaying the evolution of the ratio of duplicated core genes. E Spearman correlation analysis that illustrates the relationship between genome size (x-axis) and the ratio of duplicated core genes (y-axis) in Fusarium. Each data point represents a species (p-value < 2.2 × 10^-16, rho = 0.720358). F Spearman correlation analysis that illustrates the relationship between genome size (x-axis) and GC content (y-axis) in Fusarium (p-value = 0.5707, rho = -0.03878989). G Spearman correlation analysis that illustrates the relationship between whole genome GC content (x-axis) and conserved core gene CDS sequences GC content (y-axis) in Fusarium (p-value < 2.2 × 10^-16, rho = 0.6038318)
