Fig. 1: Assembly and structural evolution of the Stenogyne calaminthoides genome.
From: Allopolyploid origin and diversification of the Hawaiian endemic mints
a Photo of Stenogyne calaminthoides (credit: V.A.A.). b Hi-C contact map with inferred chromosomes in blue boxes. c Gene and repeat landscape of S. calaminthoides genome with outer to inner tracks showing genes (purple), Copia (blue), Helitron (green), and Gypsy (red) repeats, respectively. Density over 1 Mb intervals is shown by black lines. Regions of synteny are shown in the center and each pair shares a color. Scaffold number is shown on the exterior. d Fractionation bias plot of S. calaminthoides mapped onto Vitis vinifera chromosome 10. Each coloured line represents a S. calaminthoides scaffold. e Schematic phylogenetic tree showing inferred polyploid events in Stenogyne, with the triangle representing the gamma paleohexaploidy found in all core eudicots, the blue circle representing a whole genome duplication (WGD) found in most core Lamiales, and the pink circle representing the WGD event exclusive to Stenogyne. Source data for Figs. 1c and 1d are provided as a Source Data file.
