Genetic structuring in a Neotropical palm analyzed through an Andean orogenesis‐scenario

open access: yesEcology and Evolution, Volume 8, Issue 16, Page 8030-8042, August 2018., 2018
Andean orogeny explains the structuring of genetic diversity in the palm Oenocarpus bataua into four genetic clusters within northwestern South America. These clusters maintain genetic exchange between them, even across the Andes. A hotspot of genetic diversity was determined in the northern Peruvian Amazonia.

[Retracted] Naturally Occurring Xanthones: Chemistry and Biology

open access: yesJournal of Applied Chemistry, Volume 2013, Issue 1, 2013., 2013
Xanthones are one of the biggest classes of compounds in natural product chemistry. A number of xanthones have been isolated from natural sources of higher plants, fungi, ferns, and lichens. They have gradually risen to great importance because of their medicinal properties.

Foliar colleters inMacrocarpaea obtusifolia(Gentianaceae): anatomy, ontogeny, and secretion

open access: yesBotany, 2014
Colleters are secretory structures located in reproductive and (or) vegetative organs of many eudicots. In Gentianaceae Juss., the presence of foliar colleters has been neglected, and anatomical and histochemical studies are scarce. The objectives of this study were to investigate the anatomy, ontogeny, and chemical nature of the secretion found in ...

The Short ITS2 Sequence Serves as an Efficient Taxonomic Sequence Tag in Comparison with the Full‐Length ITS

open access: yesBioMed Research International, Volume 2013, Issue 1, 2013., 2013
An ideal DNA barcoding region should be short enough to be amplified from degraded DNA. In this paper, we discuss the possibility of using a short nuclear DNA sequence as a barcode to identify a wide range of medicinal plant species. First, the PCR and sequencing success rates of ITS and ITS2 were evaluated based entirely on materials from dry ...
