Figure 3

(A) within the 36 Aldama samples and (B) among three Aldama species (Aldama anchusifolia, A. dentata, A. trichophylla) plus outgroups of Heliantheae sequenced in this study and obtained from GenBank: Pappobolus lanatus, Tithonia diversifolia, Helianthus tuberosus, Iostephane heterophylla, Dimerostemma asperatum, Echinaceae paradoxa (NC_034320), Helianthus argophyllus (NU314500), and Helianthus annuus (NC_007977) (window length: 800 bp, step size: 200 bp). X-axis, position of the midpoint of each window; Y-axis, nucleotide diversity (π) of each window. (C–D) Twenty-seven most variable protein-coding genes within the 36 Aldama plastomes assembled. (C) percentage of variable sites according to gene length. (D) Number of variable sites per gene.
