From: A large-scale population based organelle pan-genomes construction and phylogeny analysis reveal the genetic diversity and the evolutionary origins of chloroplast and mitochondrion in Brassica napus L.

Population structure of B. napus accessions and its two progenitor species. A PCA plot of assembled cp genomes. B Chloroplast phylogeny of assembled B. napus combined together with 199 B. rape, 119 B. oleoracea and 31 synthetic B. napus accessions. C Mitochondria phylogeny of B. napus and its two progenitor species. D PCA plot of assembled mt genomes. ML phylogenetic tree were constructed using SNPs after filtering loci with minor allele frequencies (MAFs) < 0.005 and missing calls > 20%. In PCA plots, samples of different cytoplasmic types were highlighted as dots in different colors. In phylogenetic tree, the cytoplasmic type of each sample was annotated at outer circle as a vetical bar highlighted in different colors. Labels for each sample in phylogenetic tree were also highlighted with four other colors corresponding to groups as follows: black, natural B. napus; red, synthetic B. napus; yellowgreen, B. olracea; cyan, B. rapa
