Phylogenetic relationship among chloroplast genomes of white oak species representing Old World and New World lineages.

<p>The best maximum likelihood tree is shown for four white oak chloroplast genomes (<i>Q</i>. <i>mongolica</i>; <i>Q</i>. <i>robur</i>; <i>Q</i>. <i>petraea</i>; <i>Q</i>. <i>alba</i>) and one outgroup genome (<i>Q</i>. <i>rubra</i>). Inferred branch lengths in maximum likelihood substitutions are shown in bold, and bootstrap support values are show in italics. The phylogenetic resolution of informative indel markers are shown in black inverted triangles, and the resolution of the diagnostic PCR-RFLP marker is shown as a grey triangle.
