Taxonomy of Juniperus in Iran: Insight from Dna Sequencing
نویسندگان
چکیده
Sequence data from four gene regions (nrDNA, petN-psbM, trnD-trnT, trnS-trnG, 3,705 bp) revealed that junipers from the southern mountain ranges of Iran are very diverse. The combined NJ tree (3,705 bp) showed strong support for the distinct nature of J. excelsa, J. polycarpos, J. p. var. turcomanica, and J. p. var. seravschanica. The samples from NW Iran are J. polycarpos and samples from NE Iran are clearly J. p. var. turcomanica, as are the samples from Fasa in SW Iran. The samples from nearby south central Iran (Khabr) are part of a clade with J. p. var. seravschanica. However, the divergence of the Khabr and Kuhbanan junipers from J. p. var. seravschanica (9 bp or more) is so great that a new taxon may be present in southern Iran.

Introduction: The DNA sequencing is the most important technique in molecular biology by which the order of the nucleotides can be identified in a piece of DNA. There are several different methods for sequencing the DNA. Now, the DNA sequencing has great importance in the medical diagnostics and other medical fields. Some methods have been invented to speed up and increase the efficiency of the...

Analyses of individuals classically treated as Juniperus oxycedrus L. var. oxycedrus from Morocco, Portugal, Spain, France, Italy, Greece and Turkey, using DNA sequencing of nrDNA (ITS 1, 5.8S, ITS 2) plus RAPDs, leaf terpenoids and morphology revealed that two cryptic, genetically distinct but morphologically almost identical species are present. These species, J. oxycedrus L. var. oxycedrus a...
متن کاملMolecular characterization and RAPD analysis of Juniperus species from Iran.
The genus Juniperus L. (Cupressaceae), an aromatic evergreen plant, consists of up to 68 species around the world. We classified five species of Juniperus found in Iran using molecular markers to provide a means for molecular identification of Iranian species. Plants were collected (three samples of each species) from two different provinces of Iran (Golestan and East Azarbayejan). The DNA was ...

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...

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. ...
