The high level of morphological diversity, extensive inter-species hybridization, and low level of DNA sequence variation among species in this group have impeded the progress of taxonomic and phylogenetic studies.

Species of the section <em>Populus<\/em> (<em>Leuce<\/em>) clustered together suggesting monophyly of the section <em>Populus<\/em>. The Eurasian members of section <em>Populus<\/em> (<em>P. alba, P. davidiana,<\/em> and<em> P. tremula<\/em>) showed closer genetic relationships to each other than to two North American aspens (<em>P. tremuloides<\/em> and <em>P. grandidentata<\/em>) of the same section. In contrast to previous phylogenetic studies, <em>P. nigra<\/em> showed a close genetic relationship to species of the section <em>Tacamahaca<\/em>. This relationship is in agreement with various phenotypic traits, interfertility and chemistry of bud exudates and serves as evidence for introgression between <em>P. nigra<\/em> and species of the section <em>Taccamahaca.<\/em> Overall, the genetic relatedness estimates based on nuclear ISSR data were congruent with phylogenetic trees based on other molecular (RFLP and DNA sequence) and morphological data, but provided better resolution in assessing the genetic relatedness among closely related taxa, and provided genetic evidence for previously suspected introgressions.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Published in Journal of the Torrey Botanical Society\u00a0133(4): 519-527.
