Phylogenetic Analysis of Bignoniaceae Based on the cpDNA Gene Sequences rbcL and ndhF

Abstract

A phylogenetic analysis of the Bignoniaceae and related families was conducted using the DNA sequences of the chloroplast genes rbcL and ndhF. Trees were constructed using each gene separately and in a combined data set. The analysis suggested that the family is more derived within the order Lamiales sensu lato than once believed. Paulownia and Schlegelia previously have been placed in Bignoniaceae or Scrophulariaceae. However, the sequence data presented here do not support their placement in Bignoniaceae. Excluding Paulownia and Schlegelia, Bignoniaceae were found to be monophyletic. Tribes Bignonieae, Crescentieae, and Coleeae each forms a monophyletic group based on this analysis. Tribe Tecomeae is paraphyletic.
