T he goal of DNA barcoding is conceptually simple: Find one or a few regions of DNA that will distinguish among the majority of the world’s species, and sequence these from diverse sample sets to produce a large-scale reference library of life on earth (1). This approach can then be used as a tool for species identification and to help in the discovery of new species (2). Since the first DNA ba...

Climate fluctuations in the Quaternary period significantly influenced evolution and distribution of plants, which caused to a serious genetic effects speciation activity [1]. Thus, Central Asia is distinguished by wide variety flora, including 9520 species, while 20% are endemics [2]. Great phenotypic diversity wild flora Uzbekistan, numbering about 4400 species vascular plants determined pecu...

We present a five-locus 129-species phylogeny of Rutaceae from subfamily Zanthoxyloideae, with 193 ingroup samples representing 128 species all 18 genera in the Eriostemon Group and focus on generic infrageneric limits Phebalium its allies. Maximum parsimony Bayesian inference analyses were performed using three plastid markers (psbA–trnH, trnL–trnF, rbcL) two nuclear ribosomal (ITS, ETS). Aste...

With the development of open science and technological innovation, using sharing data molecular biology techniques in study taxonomy systematics have become a crucial component plants, which undoubtedly helps us discover more hidden outliers or deal with difficult taxa. In this paper, we take Dennstaedtia smithii as an example, based on database, virtual herbarium plant photo bank, to clarify t...

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...

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 ...
