Phylogenetic relationships of the Polygonaceae, inferred by maximum likelihood (ML) based on complete plastome sequences. Accessions of the species used in the phylogenetic tree are provided in Table S1, S2. Values above branches are bootstrap support (BS). Illustrations represent the junctions of the inverted repeat (IR) and the single-copy (SC) regions. The color blocks in the phylogenetic tree correspond to different types of IR/SC boundaries
