In contrast to well-established internal ribosomal entry site (IRES)-mediated translational initiation in animals and plants, no IRESs were established in fungal viral or cellular RNAs. To identify IRES elements in mycoviruses, we developed a luciferase-based dual-reporter detection system in Cryphonectria parasitica, a model filamentous fungus for virus-host interactions. A bicistronic constru...

This study aims to produce a mix of enzymes through Solid State Fermentation (SSF) raw materials. Four different, easily available, agro-industrial wastes were evaluated as SSF substrates for production by Cryphonectria parasitica (Murr.) Barr. environmental strains named CpA, CpB2, CpC4, and CpC7. Among the tested wastes, organic wheat bran human use animal feed better supports C. growth prote...

Previously we showed in laboratory studies that the fungivorus nematode, Aphelenchoides hylurgi, was attracted to and fed upon the chestnut blight fungus, Cryphonectria parasitica, from American chestnut bark cankers and was a carrier of biocontrol, white hypovirulent C. parasitica strains. In the present field study, we recovered Aphelenchoides spp. in almost all (97.0 %) of 133 blight canker ...

ABSTRACT Cryphonectria cubensis is the causal agent of a serious canker disease of Eucalyptus spp. in tropical and subtropical parts of the world. In this study, a South African C. cubensis isolate was transfected by electroporation with a synthetic RNA transcript corresponding to the full-length coding strand of the C. parasitica hypovirus (CHV1-EP713). Hypovirus infection resulted in pronounc...
