Analyzing the phylogeny of poplars based on molecular data.

ABSTRACT: Methods for constructing trees using DNA sequences, known as molecular phylogenetics, have been applied to analyses of phylogenetic origin, evolutionary relatedness and taxonomic classification. Combining data sequenced in this study and downloaded from GenBank, we sampled 112 (chloroplast data) / 122 (ITS data) specimens belonging to 49 (chloroplast data) / 46 (ITS data) poplar species or hybrids from six (chloroplast data) / five sections (ITS data). Maximum parsimony and Bayesian inference were used to analyze phylogenetic relationships within the genus Populus based on eight chloroplast combinations and ITS regions. The results suggested that Bayesian inference might be more suitable for the phylogenetic reconstruction of Populus. All Populus species could be divided into two clades: c
