Fig. 3From: Assembly and analysis of the complete Salix purpurea L. (Salicaceae) mitochondrial genome sequencePhylogenetic tree of representative higher plant mitochondrial genomes. The phylogenetic tree was constructed using the neighbor joining method with 23 mitochondrial protein-coding genes from 23 representative plant mitochondrial genomes. Numbers at the nodes are bootstrap support values. G. biloba was designated the outgroup. Taxonomic orders were indicated at rightBack to article page
