Circos diagram of miRNA gene pairs between B. rapa and A. thaliana. Conserved miRNAs genes in B. rapa are plotted against their syntenic counterparts in A. thaliana. The individual chromosomes of B. rapa (Br) and A. thaliana (At) have 24 ancestral karyotype genome building blocks demonstrating the shared ancestral origin of their genomes. The black and gray dots represent novel and conserved miRNA genes, respectively, of each genome within a 500 kb interval. The syntenic counterparts of conserved miRNAs between the genomes are interconnected by colored lines.
