title: Chloroplast genome phylogenetics: why we need independent approaches to plant molecular evolution.
abstract: The traditional approach to plant molecular phylogenetics involves amplifying, sequencing and analyzing one or a few genes from many species and is conducive to broad taxon sampling. An independent approach involves chloroplast genome sequencing, providing much larger amounts of data per taxon but for a smaller number of species. In principle, the two strategies can inform each other but in practice their results sometimes conflict for reasons that are currently debated. An Opinion article published in the October 2004 issue of Trends in Plant Science cautioned against the pursuit of genome-based phylogenies. Here, we provide a different perspective on issues at the heart of the current debate and defend the use of chloroplast genome phylogenetics for crucial species because it provides an independent test of hypotheses generated by the traditional approach.
