Fig. 2.

Circos plot represents the organelle genomes of R. nivale subsp. boreale and R. vialii. (a) The length of the organelle genomes; (b) GC density; (c) Genes locations. Blue shows protein-coding genes (PCGs), red shows tRNAs, and yellow shows rRNAs; (d) PCG names and locations. The internal lines represent collinear sequences. The gray lines are homologous fragments between the mitogenomes of the two species. The red lines are homologous fragments between the mitogenome and plastome of R. nivale subsp. boreale. The green lines are homologous fragments between the mitogenome and plastome of R. vialii. The dark green blocks represent the inverted repeat (IR) regions of the plasmid genome
