Re - Examination of the Taxonomy of Juniperus Flaccida Var

چکیده
Recent DNA sequencing data have shown that J. flaccida var. flaccida, J. f. var. martinezii and J. f. var. poblana are polyphyletic taxa. Additional analysis using Random Amplified Polymorphic DNAs (RAPDs) analyses for J. durangensis, J. flaccida var. flaccida, var. martinezii, and var. poblana, J. jaliscana, J. monticola and J. standleyi revealed exactly the same pattern of relationships as seen with the sequence data. Specifically, that J. flaccida and its varieties are polyphyletic. Upon re-examination of the morphology, J. f. var. martinezii and var. poblana are recognized as distinct species: J. martinezii Perez de la Rosa and J. poblana (Mart.) R. P. Adams, stat. nov.

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...

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. ...
متن کاملTaxonomy of Juniperus deppeana varieties and formas based on nrDNA ( ITS ) , petN - psbM , trnS - trnG , trnD - trnT , trnL - trnF sequences
Juniperus deppeana has numerous disjunct populations that include four taxonomic varieties and three forms. All four varieties and two forms of Juniperus deppeana from the southwest United States, Mexico and Guatemala were analyzed by sequencing nrDNA (ITS), petN-psbM, trnS-trnG, trnD-trnT, trnL-trnF. A Bayesian tree gave support for clades of var. deppeana, NM, var. patoniana, and var. gamboan...

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...
