Supplementary data for: Joyce et al. (2023) Phylogenomic analyses of Sapindales support new family relationships, rapid Mid-Cretaceous hothouse diversification, and heterogeneous histories of gene duplication. Frontiers in Plant Science. For details on the generation of this data please see the Methods section of this publication. Data includes gene consensus sequences (XXXX_consensus.fasta), gene alignments (XXXX_aligned.fasta), cleaned gene alignments (XXXX_cleaned.fasta), concatenated alignment (concat_aln.fasta), concatenated analysis tree file (Supp7_IQTREE_230119.tre), coalescent analysis tree file (Supp6_ASTRAL_230119.tre), SORTADATE output (sortadate_3genes_312.txt), alignment for dating analyses (sortadate_3genesconcat_aln.fasta), and MCC tree files from BEAST dating analyses (MCC_RC-complete.tre; MCCtree_UC-complete.tre; MCCtree_CC-complete.tre; MCCtree_RC-complete_lognormal-sensitivity.tre; MCCtree_RC-complete_yule-sensitivity.tre).
