From: Plastome phylogenomic study of Gentianeae (Gentianaceae): widespread gene tree discordance and its association with evolutionary rate heterogeneity of plastid genes

Fig. 3

Discordance of plastid gene trees. a Principal coordinate analysis depicting ordinations of two species trees (green and pink) versus 75 plastid protein-coding gene (PCG) trees (blue) using unrooted Robinson-Foulds algorithms. Since TREESPACE only accepts groups of trees containing the same tips, rpl33 locus was removed. Genes widely used in phylogenetic studies of Gentianeae are indicated in the plots (matK, rbcL, and atpB). b Partitioned coalescence support (PCS) of each PCG. Names of 76 PCGs are labeled in red color
