Fig. S1. Phylogenetic tree of the family Amaranthaceae based on the nuclear ribosomal internal transcribed spacer (ITS) region, depicted by RAxML-NG version 0.9.0git. The evolutionary history was inferred by using the maximum likelihood method based on the SYM + I + G model. Accession numbers were listed behind each name. Statistical support values more than 50 % obtained by RAxML-NG for bootstrap probabilities (BP) with 10,000 replicates and BEAST for Bayesian posterior probabilities (PP) with 10,000,000 replicates are shown on or near nodes (BP/PP). The tree was rooted at the midpoint. The pdf of Supplementary Figure S1 can be downloadable via the web link https://www.digital-museum.hiroshima-u.ac.jp/~main/index.php/Supplementary_data.
Fig. S2. Phylogenetic tree of the family Amaranthaceae based on the chloroplast ribulose-1,5-bisphosphate carboxylase/oxygenase large-subunit (rbcL) gene sequence, depicted by RAxML-NG version 0.9.0git. The evolutionary history was inferred by using the maximum likelihood method based on the TVM + I + G model. Accession numbers were listed behind each name. Statistical support values more than 50 % obtained by RAxML-NG for bootstrap probabilities (BP) with 10,000 replicates and BEAST for Bayesian posterior probabilities (PP) with 10,000,000 replicates are shown on or near nodes (BP/PP). The tree was rooted at the midpoint. The pdf of Supplementary Figure S2 can be downloadable via the web link https://www.digital-museum.hiroshima-u.ac.jp/~main/index.php/Supplementary_data.
