Performances of different combinations of matK, rbcLb, trnH-psbA and ycf1b in resolving species in seven well-sampled plant groups representing gymnosperms, basal angiosperms, monocots, Saxifragales, rosids, and asterids. Table S1. The 144 plastid genomes used for ycf1 primer design. Table S2. The 368 samples used to test primer universality. Table S3. Taxon-specific ycf1 primers in the event of failure of the universal primers listed in Table 1. Table S4. The 490 samples collected from the Beijing Botanical Garden, CAS for candidate barcode resolution testing. Table S5. Samples of seven groups representing seed plants for candidate barcode resolution testing. The sequences of taxa without vouchers were downloaded from GenBank. Table S6. Nucleotide diversity of ycf1b together with three other markers and their species- discriminating powers in Pinus (Pinaceae). Table S7. Nucleotide diversity of ycf1b together with three other markers and their species- discriminating powers in Calycanthaceae. Table S8. Nucleotide diversity of ycf1b together with three other markers and their species- discriminating powers in Iris (Iridaceae). Table S9. Nucleotide diversity of ycf1b together with three other markers and their species- discriminating powers in Paeonia sect.
