Differences between nuclear and plastid phylogenies can also be caused by incomplete lineage sorting or hybridization, but with 27 species spread so broadly across angiosperms, the resulting topological differences would be small if existent at all Maddison and Knowlesand topology tests would likely not be significant. F igure 2. One of the most popular aims of dating analyses is to convert the genetic divergence measured between sequences of DNA into an absolute age for any internal node of a phylogenetic tree.

Inferences from tip‐calibrated phylogenies: a review and a practical guide
Markers from other genomes can provide support in favor of one method or the other, but most phylogenetic studies in plants rely solely on markers that are easy to amplify, such as plastid markers and the nuclear internal transcribed spacers ITSthe latter being extremely difficult to align among distant taxa Smith and Donoghue ; Soltis et al.
