Fig. 4From: Directed Repeats Co-occur with Few Short-Dispersed Repeats in Plastid Genome of a Spikemoss, Selaginella vardei (Selaginellaceae, Lycopodiopsida)Phylogenetic reconstruction and simplified structure of plastomes of each species. The red star represents the origination of DR structure, whereas the blue stars represent the independent origination of IR structure in SelaginellaceaeBack to article page
