Fig. 2

Circos plot showing basic characteristics of the twelve Arachis cp genomes acquired in this study. The GC content, the SND density, the indel density, and the conserved regions are shown from the inner to outer rings. The outermost rectangles are cp genes belonging to different functional groups that are color-coded. The high-density areas are highlighted in orange for GC content (> 53.06%), SNDs (> 8.39%) and indels (> 5.34%). Boxplots for the GC contents, the SND and indel densities have also been shown, with bars representing the median, the bottom and top of the boxes representing, respectively, the 25 and 75% percentiles, and whiskers extending out to 1.5 times the interquartile range. Dots are outliers
