@ARTICLE{TreeBASE2Ref21722, author = {David M. Spooner and Percy Rojas and Meredith Bonierbale and Lukas A Mueller and Manish Srivastav and Douglas Senalik and Philipp W. Simon}, title = {Molecular Phylogeny of Daucus}, year = {2013}, keywords = {Daucus, molecular phylogeny, taxonomy, Umbelliferae.}, doi = {}, url = {http://}, pmid = {}, journal = {Systematic Botany}, volume = {}, number = {}, pages = {}, abstract = {We studied the phylogeny of 22 accessions of Daucus and seven accessions in related genera, with DNA sequences from eight nuclear orthologs and one plastid (psbA/trnH) region. Maximum parsimony and maximum likelihood analyses of the concatenated data matrix of 7,212 aligned nucleotides provided excellent bootstrap support for many clades. Concordant with prior molecular results Pseudorlaya pumila was firmly imbedded within Daucus, as was Margottia gummifera, a new finding. All accessions of D. capillifolius, D. carota, and D. sahariensis formed a 2n = 18 clade with all other species within the Daucus clade with chromosome numbers of = 20, 22, and 44 (D. glochidiatus). Sister to the D. carota clade was a clade containing Margottia gummifera and Pseudorlaya pumila, sister to these species was D. crinitus, sister to all the above was D. muricatus, and sister to all of the above was a clade containing the remaining Daucus species. Bayesian analyses of individual regions analyzed separately and averaged over multiple trees with *BEAST software (a coalescent approach), however, provided a phylogeny at variance with the concatenated approach, most notably in firmly imbedding Turgenia latifolia within Daucus. Our research highlights the need for additional morphological and molecular studies in preparation for a modern taxonomic monograph of Daucus.} }
