Diaporthe (anamorph = Phomopsis) species are plant pathogens and endophytes on a wide range of hosts including economically important crops. At least four Diaporthe taxa occur on soybean and they are responsible for serious diseases and significant yield losses. Although several studies have extensively described the culture and morphological characters of these pathogens, their taxonomy has no...

A new quinone derivative, named epoxyquinophomopsin (1), was isolated from the EtOAc extract of the fermentation broth culture of an endophytic fungus Phomopsis sp. from Morus cathayana. Structure of compound 1 was determined mainly by NMR and mass spectral data. Biogenetically compound 1 can be regarded as a degradative product of the previously reported anthraquinone found in the fungus.

Many compounds produced by fungi have relevant pharmaceutical applications. The purpose of this study was to collect and isolate endophytic fungi from different regions of Panama and then to test their potential therapeutic activities against Leishmania donovani, Plasmodium falciparum, and Trypanosoma cruzi as well as their anticancer activities in MCF-7 cells. Of the 25 fungal isolates obtaine...

Fungal endophytes live in the inner tissues of Clerodendrum inerme and may be significant resources for new chemicals in drug discovery. A total of 242 endophytic fungi were recovered from 602 sample segments of C. inerme; 66 were purified. The 66 fungi belonging to 16 taxa and 11 genera (Alternaria, Nigrospora, Bartalinia, Pestalotiopsis, Fusarium, Mycoleptodiscus, Trichoderma, Phomopsis, Diap...

Throughout many years of studying mycopopulation of weeds, we have found fungi of the Diaporthe/ Phomopsis complex interesting to research. After years of examining plants of Achillea millefolium L., some of them exhibited symptoms of infection typical for Diaporthe/Phomopsis species. A. millefolium was usually found in uncultivated, pasture and forest flora, but also in or nearby sunflower fie...

The identification of Diaporthe (anamorph Phomopsis) species associated with stem canker of sunflower (Helianthus annuus) in Australia was studied using morphology, DNA sequence analysis and pathology. Phylogenetic analysis revealed three clades that did not correspond with known taxa, and these are believed to represent novel species. Diaporthe gulyae sp. nov. is described for isolates that ca...

In the present study, an attempt to evaluate the antimicrobial and antioxidant activity of fungal endophytes inhabiting Emblica officinalis has been made keeping in view the medicinal importance of the selected host plant in Indian traditional practices. A total of four endophytic fungi belonging to Phylum Ascomycetes were isolated from different parts of the plant which were characterized morp...

The Y-chromosome haplogroup N-M231 (Hg N) is distributed widely in eastern and central Asia, Siberia, as well as in eastern and northern Europe. Previous studies suggested a counterclockwise prehistoric migration of Hg N from eastern Asia to eastern and northern Europe. However, the root of this Y chromosome lineage and its detailed dispersal pattern across eastern Asia are still unclear. We an...

Because rotavirus diarrhea can be reduced through vaccination and because current vaccine candidates provide protection against only the most common G antigenic types (G1 to G4), detection of uncommon G types is one of the main goals of rotavirus surveillance. After a 2-year nationwide rotavirus surveillance study in Argentina concluded, surveillance was continued and an increase of G9 prevalen...
