Phylogenetic relationships in Gleditsia (Leguminosae) based on ITS sequences
We used nucleotide sequences from the internal transcribed spacers and 5.8S gene of nuclear ribosomal DNA to test competing phylogenetic and biogeographic hypotheses in Gleditsia . Eleven of 13 Gleditsia species were sampled, along with two species of its sister genus, Gymnocladus . Analyses of ITS...
