Phylogeny of G. coronaria and seven other representative species of Asteraceae. (a) Phylogenetic tree of 8 Asteraceae species built on the gene trees of 2,456 orthogroups with at least 88.9% of species having single-copy genes in any orthogroup, using the STAR and STRIDE methods invoked in OrthoFinder2 with parameters ‘-M msa -A mafft -T fasttree -1 -y’. Float numbers on branches indicate number of substitutions per amino acid site. (b) Time tree of eight Asteraceae species, estimated using RelTime method of MEGA11 with one calibration of the divergence of Coffea and Asteraceae at 95–106 MYA. Float numbers at internodes refer to the estimated species divergence time.
