jpy12131-sup-0001-AppendixS1.nextext/nex1037KFigure S1. Phylogram depicting the best tree from the Maximum Likelihood and Bayesian phylogenetic analyses. Nodes with double asterisks (**) denote clades with ≥100% bootstrap support and ≥1.00 posterior probability, while nodes with single asterisks (*) denote clades with ≥75% bootstrap support and ≥0.95 posterior probability. The mediophycean clade is collapsed here for clarity and shown in Figure 1.
jpy12131-sup-0002-FigureS1.tifimage/tif4777KTable S1. Taxa used in phylogenetic analysis, with locality, Theriot Lab specimen voucher ID (HK###) and GenBank accession numbers. Taxa marked with asterisks were used in Theriot et al. (2010) but were misidentified in that manuscript (* = “Biddulphia alterans”; ** = “Isthmia enervis”; *** = “Coscinodiscus concinniformis”).
jpy12131-sup-0003-TableS1.docWord document246KAppendix S1. Aligned DNA sequence data in NEXUS format. Sequences for the 3 genes of each taxon are sequential, starting with nuclear-encoded ribosomal small-subunit (bases 1–1,706), chloroplast-encoded rbcL (bases 1,707–3,178) and chloroplast-encoded psbC (bases 3,179–4,238).
