Rethinking phylogenetics using Caryophyllales (angiosperms), matK gene and trnK intron as experimental platform
… appear to impact resolution or support in the Gnetales indicating that edited sites in such low proportions do not need to be a consideration when building datasets. We also propose an alternate start codon for matK in Ephedra based on the presense of a 38 base pair indel in several species …
