Comparative analysis of six <i>Allium</i> plastomes and 45S nrDNA sequences.

(A) Variations observed among six Allium plastomes. (B) Variations observed among six Allium 45S nrDNA sequences. (C) Phylogenetic relationships among six Allium samples based on whole plastome sequences (excluding one copy of IR region) and 45S nrDNA sequences. The plastome and 45S nrDNA sequences of A. cepa were included as the outgroup. The phylogenetic tree on the left is based on plastomes, while the one on the right is based on 45S nrDNA sequences. Bootstrap values greater than 50% are shown near the branches. The colored lines in the middle highlight comparisons between the two trees.
