Fig. 6: Evolution of patchouli genome.

a ASTRAL-III tree with summary of conflicting and concordant gene trees produced with Phyparts (v0.0.1). For each branch, the top number indicates the number of gene trees concordant with the species tree at that node, and the bottom number indicates the number of gene trees in conflict with that clade in the species tree. The pie charts at each node present the proportion of gene trees support each type. b Kernel density plots for corrected Ks between genomes among patchouli subgenome A, patchouli subgenome B, Scutellaria barbata, and Vitis vinifera genomes. c Evolutionary scenario of patchouli genome. Solid line represents chromosomes from I group, mosaic line represents chromosomes from II group. Orange line represent chromosomes from subgenome A and cyan line represent chromosomes from subgenome B. MYA is an abbreviation for million years ago.
