BACKGROUND Medicinal plant trade is important for local livelihoods. However, many medicinal plants are difficult to identify when they are sold as roots, powders or bark. DNA barcoding involves using a short, agreed-upon region of a genome as a unique identifier for species- ideally, as a global standard. RESEARCH QUESTION What is the functionality, efficacy and accuracy of the use of barcod...

A naturally occurring atrazine-resistant cyanobacterial isolate, strain SG2, was isolated from an atrazine-containing wastewater treatment system at the Syngenta atrazine production facility in St. Gabriel, La. Strain SG2 was resistant to 1,000 microg of atrazine per ml but showed relatively low resistance to diuron [3-(3,4-dichlorophenyl)-1,1-dimethyl urea]. Analyses of 16S ribosomal DNA indic...

We investigate the species discriminatory power of a subset of the proposed plant barcoding loci (matK, rbcL, rpoC1, rpoB, trnH-psbA) in Carex, a cosmopolitan genus that represents one of the three largest plant genera on earth (c. 2000 species). To assess the ability of barcoding loci to resolve Carex species, we focused our sampling on three of the taxonomically best-known groups in the genus...

Harmful algal blooms occur all over the world, destroying aquatic ecosystems and threatening other organisms. The culture supernatant of the marine algicidal actinomycete BS01 was able to lysis dinoflagellate Alexandrium tamarense ATGD98-006. Physiological and biochemical responses to oxidative stress in A. tamarense were investigated to elucidate the mechanism involved in BS01 inhibition of alg...

The most widely distributed dinoflagellate plastid contains chlorophyll c(2) and peridinin as the major carotenoid. A second plastid type, found in taxa such as Karlodinium micrum and Karenia spp., contains chlorophylls c(1) + c(2) and 19'-hexanoyloxy-fucoxanthin and/or 19'-butanoyloxy-fucoxanthin but lacks peridinin. Because the presence of chlorophylls c(1) + c(2) and fucoxanthin is typical o...

Selective inhibition of gene expression by antisense oligodeoxynucleotides (ODNs) is widely applied in gene function analyses; however, experiments with ODNs in plants are scarce. In this work, we extend the use of ODNs in different plant species, optimizing the uptake, stability, and efficiency of ODNs with a combination of molecular biological and biophysical techniques to transiently inhibit...

Since the pre-historic era, humans have been using forests as a food, drugs and handcraft reservoir. Today, the use of botanical raw material to produce pharmaceuticals, herbal remedies, teas, spirits, cosmetics, sweets, dietary supplements, special industrial compounds and crude materials constitute an important global resource in terms of healthcare and economy. In recent years, DNA barcoding...

The identification of flowering plants using DNA barcoding proposed in last decades has slowly gained ground Africa, where it been successfully used to elucidate the systematics and ecology several plant groups, understand their evolutionary history. Existing inferences on effectiveness identify African trees are mostly based lowland forests, whereas adjacent montane forests significantly diffe...

Genus Paphiopedilum has species having lovely flowers which are incredibly attractive to everyone. Their ornamental and commercial value caused over-collection illegal poaching trade. Due these reasons, nowadays, the Venus slipper orchids facing deplete in nature. Therefore, it is important consider conservation. Mainly, necessary prioritize identification phylogenetic analysis methods of genus...

The genus Centaurea s.l. is one of the richest and most taxonomically complex Asteraceae family. It includes between 400 700 species, which more than 70 are found in Bulgaria – a territory considered as secondary centers speciation genus. There large number endemics (Bulgarian Balkan) with endemism reaching up to 50% some groups, such Cyanus gr. Due ongoing active Balkans, boundaries closely re...
