Ganoderma has been considered a very difficult genus among the polypores to classify and is currently in a state of taxonomic chaos. In a study of Ganoderma collections including numerous type specimens, we found that six species namely G. cupreum, G. densizonatum, G. limushanense, G. mastoporum, G. orbiforme, G. subtornatum, and records of G. fornicatum from Mainland China and Taiwan are very ...

Cuscuta is the only parasitic genus in Convolvulaceae family. This genus is globally distributed, with most species in the tropics, subtropics, and some in the temperate regions. In this study, the micro-morphological features and molecular evidencesof 12 populations from three species of Cuscuta (C. australis, C. campestris,and C. chinensis) have been considered. In total, seven quantitative a...

The taxonomy and phylogeny of Asian Meconopsis (Himalayan blue poppy) remain largely unresolved. We used the internal transcribed spacer (ITS) region of nuclear ribosomal DNA (nrDNA) and the chloroplast DNA (cpDNA) trnL-F region for phylogenetic reconstruction of Meconopsis and its close relatives Papaver, Roemeria, and Stylomecon. We identified five main clades, which were well-supported in th...

The genus Brevicellicium encompasses wood-inhabiting corticioid fungi characterized by isodiametric subhymenial hyphae, short basidia, and smooth, often subangular spores with a distinct apiculus. Eight new LSU nrDNA sequences and 13 new ITS nrDNA of this genus, including the type species, were aligned with 47 and 42 accessions respectively of species of Trechisporales obtained from GenBank, an...

Dried parts of different plant species often look alike, especially in powdered form, making them very difficult to identify. Ruta graveolens, sold as a dried medicinal herb, can be adulterated with Euphorbia dracunculoides. The genomic DNA was isolated from the leaf powder (100 mg each) using the modified CTAB method. Internal transcribed spacer sequences of nuclear ribosomal DNA (nrDNA-I...

This work aims to analyze the phylogeography of Schizolobium parahyba(Fabaceae), which includes two varieties with a disjunct distribution, from Southern Brazil to Central America. Neotropical rain forests, focus on four largest wet forests: Atlantic forest, Amazonian forests, Andean forest and Central America forest. The genetic diversity and differentiation of populations among S. parahyba po...
