چکیده

A robust analysis of Juniperus, sect. Juniperus is presented based on nrDNA and five cpDNA regions. The section is clearly divided into two groups composed of blue and red seed cone species and is composed of four major clades: J. communis and allies; J. cedrus oxycedrus allies; J. brevifolia deltoides navicularis; and a loose clade of J. formosana, f. var. mairei, and J. communis var. jackii. Juniperus c. var. jackii was found to be the most divergent taxon in the blue seed cone group and is recognized at the specific level: Juniperus jackii (Rehder) R. P. Adams, comb. nov. Juniperus formosana and var. mairei were found to be very distinct and the DNA data supports the recognition of J. mairei Lemee & H. Lev. The DNA data also support the recognition of J. lutchuensis Koidz. and J. communis var. hemisphaerica (J. & C. Presl) Parl. The putative J. communis var. saxatilis from Kamchatka peninsula, Russia was found to be unique in its DNA sequence and was recognized as: Juniperus communis var. kamchatkensis R. P. Adams, var. nov. Phytologia 94(2): 280-297 (August 1, 2012).

TAXONOMY OF JUNIPERUS COMMUNIS IN NORTH AMERICA: INSIGHT FROM VARIATION IN nrDNA SNPs

Plants of Juniperus communis L. var. communis, J. c. var. depressa Pursh, J. c. var. jackii Rehdr, J. c. var. saxatilis Pall. were sampled and SNPs from nrDNA were examined. Based on these data and previous data, a new variety of J. communis is recognized: Juniperus communis var. charlottensis R. P. Adams, var. nov. It occurs in muskeg bogs on Queen Charlotte Island, British Columbia and in the...

Reticulate evolution in Thuja inferred from multiple gene sequences: implications for the study of biogeographical disjunction between eastern Asia and North America.

The eastern Asia-North America disjunction is one of the most interesting biogeographical patterns, but its formation is still in much debate. Here nucleotide sequences of five cpDNA regions, nrDNA ITS and two low-copy nuclear genes (LEAFY, 4CL) were employed to reconstruct the phylogeny and to explore the historical biogeography of Thuja, a typical eastern Asia-North America disjunct genus. Hi...

Molecular Phylogeny of Asian Meconopsis Based on Nuclear Ribosomal and Chloroplast DNA Sequence Data

The taxonomy and phylogeny of Asian Meconopsis (Himalayan blue poppy) remain largely unresolved. We used the internal transcribed spacer (ITS) region of nuclear ribosomal DNA (nrDNA) and the chloroplast DNA (cpDNA) trnL-F region for phylogenetic reconstruction of Meconopsis and its close relatives Papaver, Roemeria, and Stylomecon. We identified five main clades, which were well-supported in th...

Divergent and reticulate species relationships in Leucaena (Fabaceae) inferred from multiple data sources: insights into polyploid origins and nrDNA polymorphism.

Previous analyses of species relationships and polyploid origins in the mimosoid legume genus Leucaena have used chloroplast DNA (cpDNA) restriction site data and morphology. Here we present an analysis of a new DNA sequence data set for the nuclear ribosomal DNA (nrDNA) 5.8S subunit and flanking ITS 1 and ITS 2 spacers, a simultaneous analysis of the morphology, ITS and cpDNA data sets for the...

Towards a more robust molecular phylogeny of Chinese Apiaceae subfamily Apioideae: additional evidence from nrDNA ITS and cpDNA intron (rpl16 and rps16) sequences.

China contains some of the world's greatest diversity of Apiaceae (Umbelliferae), with ten endemic genera. Our previous investigation into the phylogenetic relationships of Chinese Apiaceae subfamily Apioideae, based exclusively on nrDNA ITS sequences, revealed several major clades heretofore unrecognized in the subfamily and confirmed the phylogenetic placements of five endemic genera. To furt...
