A phylogeny of Boronia (Rutaceae) is presented on the basis maximum parsimony and Bayesian analyses plastid (psbA–trnH, trnL–trnF, rbcL) nuclear (ITS, ETS) markers. Analyses either or sequences recovered same major clades, although with conflicts in resolution among them. The existing classification largely confirmed; sections Boronella, Pedunculatae Valvatae are supported, monotypic Alatae Imb...
The order Laurales comprises a few indisputed core constituents, namely Gomortegaceae, Hernandiaceae, Lauraceae, and Monimiaceae sensu lato, and an equal number of families that have recently been included in, or excluded from, the order, namely Amborellaceae, Calycanthaceae, Chloranthaceae, Idiospermaceae, and Trimeniaceae. In addition, the circumscription of the second largest family in the o...
The genus Stachys is one of the largest in Lamiaceae family. Representatives are among most ancient medicinal plants used ethnomedicine. Balkan endemic species S. thracica , bulgarica and scardica included Red Data Book Bulgaria due to their endangered status scarcely studied. aim present work was examine genetic these three during process ex situ conservation. To gain information about taxonom...
Abstract The aim of DNA barcoding is to enable fast and accurate species identification. However, universal plant barcodes often do not provide species-level discrimination, especially in taxonomically complex groups. Here we use Lauraceae for the design evaluation strategies, considering: (1) efficacy taxon-specific barcode regions compared with discrimination; (2) how extent intra- interspeci...
Plant DNA barcoding currently relies on the application of a two-locus combination, matK + rbcL. Despite the universality of these two gene regions across plants, it is suspected that this combination might not have sufficient variation to discriminate closely related species. In this study, we tested the performance of this two-locus plant barcode along with the additional plastid regions trnH...
BACKGROUND Identification keys are decision trees which require the observation of one or more morphological characters of an organism at each step of the process. While modern digital keys can overcome several constraints of classical paper-printed keys, their performance is not error-free. Moreover, identification cannot be always achieved when a specimen lacks some morphological features (i....
Despite considerable progress, many details regarding the evolution of the Arcto-Tertiary flora, including the timing, direction, and relative importance of migration routes in the evolution of woody and herbaceous taxa of the Northern Hemisphere, remain poorly understood. Meehania (Lamiaceae) comprises seven species and five subspecies of annual or perennial herbs, and is one of the few Lamiac...
Calligonum is the only C4 genus within Polygonaceae. We applied DNA sequences from nuclear ribosomal internal transcribed spacer (nrITS) and five plastid genome regions (psbA-trnH, ycf6-psbM, trnL-F, rpl32-trnL rbcL) to reconstruct phylogeny of Calligonum. The nrITS combined were analysed separately. supports treatment mongolicum complex as a single species with intra-specific geographic struct...
A two-marker combination of plastid rbcL and matK has previously been recommended as the core plant barcode, to be supplemented with additional markers such as plastid trnH-psbA and nuclear ribosomal internal transcribed spacer (ITS). To assess the effectiveness and universality of these barcode markers in seed plants, we sampled 6,286 individuals representing 1,757 species in 141 genera of 75 ...
