Aspergillus flavus is the major producer of carcinogenic aflatoxins in crops worldwide and is also an important opportunistic human pathogen in aspergillosis. The sexual state of this heterothallic fungus is described from crosses between strains of the opposite mating type. Sexual reproduction occurred between sexually compatible strains belonging to different vegetative compatibility groups. ...

The dry rot fungus Serpula lacrymans is a devastating basidiomycete occurring in wooden constructions in temperate regions worldwide. In this study, we compare the genetic structures of two invasive populations from Europe and Japan. Microsatellite data from 14 loci and DNA sequences from four loci demonstrated that the two populations were highly differentiated. Significant isolation by distan...

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...

in the present study, vegetative compatibility groups (vcg) of 27 isolates of fusarium solani collected from root and  crown of sugar beets of different provinces in iran were determined using nitrate non– utilizing (nit) mutants. totally, 222 nit mutants were generated from 27 isolates using pdc medium. based on the weak growth on basal medium containing one of four nitrogen sources the phenot...

Sphaeropsis sapinea is an endophyte and latent pathogen of pines, assumedly introduced to the Southern Hemisphere along with its host. There are at least three recognised forms of S. sapinea that differ from each other morphologically and can also be separated based on molecular characteristics. Pinus radiata is a native to California but has been used extensively for afforestation in the South...

Compatibility of the entomopathogenic fungus, Metarhizium anisopliae with representative pesticides, plant oils and a fungal antagonist were studied in vitro. The pesticides tested were: endosulfan, acephate, abamectin, ethion, chlorothalonil, iprodion + carbendazim, thiophanate methyl and dinocap, an antagonist, Trichoderma harzianum and the plant oils: coconut oil, groundnut oil, gingili oil,...

In filamentous fungi, vegetative compatibility among individuals of the same species is determined by the genes encoded at the heterokaryon incompatibility (het) loci. The hyphae of genetically similar individuals that share the same allelic specificities at their het loci are able to fuse and intermingle, while different allelic specificities at the het loci result in cell death of the interac...
