Fig. 2: S. splendens evolutionary history.
From: Chromosome-scale assembly and evolution of the tetraploid Salvia splendens (Lamiaceae) genome
a Comparison with ancestral eudicot karyotype (AEK) chromosomes reveals synteny. The syntenic AEK blocks are painted onto S. splendens chromosomes. b Inferred phylogenetic tree, divergence time, whole-genome duplication (WGD), and whole-genome triplication (WGT). c Ks distribution. y axis, S. splendens paralogs (green), T. grandis paralogs (blue), and S. splendens – V. vinifera orthologs (red). Polyploidization (WGD-1, WGD-2, WGD-3 and WGT-γ) events are referenced on the x axis. d Dot plots of paralogs in S. splendens and T. grandis that illustrate WGD-1, WGD-2 (1:4 chromosomal relationships in green circles), and WGD-3 (1:2 chromosomal relationships in blue circles) events
