Abstract Croton is one of the largest angiosperm genera, with > 1200 species in tropics worldwide. The arborescent section Cleodora stands out for its disjunct geographical distribution two main centres diversity Amazonian and Atlantic Forest regions, separated by Caatinga, Cerrado Chaco biomes (the ‘Dry Diagonal’). This disjunction found other Neotropical lineages attributed to Neogene ...

Background and aims – Pollination systems often reflect adaptations to specific groups of pollinators, these morphological specialisations have been important in the diversification angiosperms. Here, we study evolution capitulum pollination system pantropical genus Parkia, which comprises 35 species trees distributed largely forests South Central America, Africa, Madagascar, Indo-Pacific. The ...

Abstract— Previous phylogenetic analysis of ITS nrDNA sequence data for Arctotidinae species resolved a strongly supported clade containing all but one the showy annual Arctotis (informally designated Annual Clade). In present study, relationships in Clade were investigated by Bayesian inference and maximum parsimony analyses cpDNA ( trnT-trnL-trnF trnH-psbA ) (ITS) data. The phylogenies notabl...

Caryophyllaceae is a large angiosperm family, with many species being utilized as ornamental or medicinal plants in Korea, addition to several endangered that are managed by the government. In this study, we used DNA barcoding for accurate identification of Korean Caryophyllaceae. A total 78 taxa (n = 215) were sequenced based on three chloroplast regions (rbcL, matK, and psbA–trnH) nuclear rib...

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...

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...

Eranthis Salisb. (Ranunculaceae) is a herbaceous plant genus, including few species disjunctively distributed throughout the temperate zone from Southeastern Europe to Eastern Asia. Until recently, only sibirica DC. was known in South Siberia, being considered endemic and tertiary relict. Not long ago, tanhoensis Erst also described Siberia. We report here reconstruction of phylogenetic relatio...
