Fig. 1: Geographic distribution of samples and genetic relationships.
From: Backcrossing to different parents produced two distinct hybrid species
A Distributiones of P. wilsonii, P. purpurea, P. farreri and P. likiangensis var. rubescens, P. likiangensis var. linzhiensis, P. likiangensis var. likiangensis, P. brachytyla sensu stricto (s.s.) and P. brachytyla-southern lineage sampled for transcriptome sequencing for this study. Different colors indicate the taxon collected as indicated. B Maximum likelihood tree based on all 186 transcriptome sequences with P. breweriana as an outgroup. C Phylogenetic network based on the W-RNA-seq dataset. D Mitochondrial genome tree of four taxonomic groups with P. glauca as an outgroup. E Plastid genome tree of four groups with P. glauca as an outgroup. PLSC: P. likiangensis species complex, red: P. likiangensis var. likiangensis, green: P. wilsonii, pink: P. purpurea, blue: P. brachytyla s.s., olive: P. likiangensis var. linzhiensis, cyan: P. farreri, linen: P. likiangensis var. rubescens, celadongreen: P. brachytyla-southern lineage.
