Plastid DNA phylogenetic tree of the seven olive tree lineages based on nucleotide substitutions from complete plastid genomes. The same topology was obtained with maximum parsimony and maximum likelihood (GTR+I+G) analyses. The bootstrap values are given on each branch (when superior to 50%), the first corresponding to the MP analysis and the second (in brackets) to the ML analysis. The Forsythia europaea and Olea woodiana sequences were used as outgroups. The tree was rooted with the Forsythia sequence. The two clades Cp-I and Cp-II are indicated according to Besnard et al. .
