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

(A) Circular map of six Allium plastomes. The species and total length are written in the center of the circular map. Annotated genes are marked on the outer circle and functions of these genes are categorized based on the legend placed in the bottom left. Red bars of the inner circle indicate SNP positions and black bars of the inner circle indicate InDel positions. (B) Map and variable sites within the 45S nrDNA sequence of six Allium samples. Gray boxes indicate transcription unit and red bars indicate variable sites among six Allium samples.
