Fig. 6From: Plastome structure, phylogenomics and evolution of plastid genes in Swertia (Gentianaceae) in the Qing-Tibetan PlateaumVISTA-based sequence identity plot of 20 Swertia plastomes compared using S. erythrosticta as a reference. The top grey arrow shows genes in order (transcription direction) and the position of each gene. A 70% cut-off was used for the plots. The vertical scale represents the percentage of identity between 50 and 100%. Coding and non-coding regions (IGS/intron) are marked in purple and red, respectively, while conserved genes are in blueBack to article page
