Figure 4From: Relationship between mRNA secondary structure and sequence variability in Chloroplast genes: possible life history implicationsGC content at synonymous and non-synonymous sites correlates positively with residual, length-adjusted stability. The Y-axis is the relative G+C content (%) averaged across all 35 genes, separately at the three codon positions. The X-axis is the residual length-adjusted stability (-ΔG), calculated as in Figure 1. The parametric correlation coefficients (r) and non-parametric Spearman's rank correlation coefficients (rs) are indicated.Back to article page
