Mating studies were conducted on 78 isolates of Fusarium species section Liseola from rice, sugarcane and maize. From the crosses with tester strains of Gibberella fujikuroi species complex, 64.1% (50 out of 78 isolates) were cross-fertile with tester strains of mating populations A to E. The results of the mating studies showed that of the 50 isolates, 19 belonged to mating population A (Gibbe...

The aerobiology of fungi in the genus Fusarium is poorly understood. Many species of Fusarium are important pathogens of plants and animals and some produce dangerous secondary metabolites known as mycotoxins. In 2006 and 2007, autonomous unmanned aerial vehicles (UAVs) were used to collect Fusarium 40–320 m above the ground at the Kentland Farm in Blacksburg, Virginia. Eleven single-spored iso...

Fusarium head blight (FHB), or scab, caused by several Fusarium species, especially Fusarium graminearum Schwabe [teleomorph Gibberella zeae (Schweinitz) Petch], is a widespread and destructive disease of wheat (Triticum aestivum L.), barley (Hordeum vulgare L.), and other small-grain cereals (Liddell 2003; Parry et al. 1995; Pirgozilev et al. 2003). These pathogens infect spikes and reduce gra...

Fusarium graminearum (teleomorph: Gibberella zeae) is an Ascomycete fungal plant pathogen which infects a range of agriculturally important crops, including wheat, barley, and maize. A random plasmid insertion mutagenesis approach was used to analyze the pathogenicity of the PH-1 strain, for which full genomic information is available. Fungal transformants were initially screened for their abil...

Mating experiments were performed among 18 strains of Fusarium pseudograminearum, formerly recognized as the Group 1 population of F. graminearum. Heterothallic production of perithecia was observed in eight out of all 153 possible combinations. Mature asci and viable ascospores were recovered in seven of the eight combinations. Perithecia in the fertile pairings were subglobose to ovoid, dark,...

Grains from 14 corn inbreds and 4 single cross hybrids were inoculated with 3 isolates of Gibberella zeae to determine their inhibition of zearalenone production. The corn hybrids: Pa762 x A632 (50 mg/kg zearalenone production), A619 x A632 (17 mg/kg zearalenone production), H95 x Mo17 (132 mg/kg zearalenone production), and B73 x MO17 (33 mg/kg zearalenone production) appear to have less resis...

Fungal infection of barley and malt, particularly by the Fusarium species, is a direct cause of spontaneous overfoaming of beer, referred to as gushing. We have shown previously that small fungal proteins, hydrophobins, act as gushing-inducing factors in beer. The aim of our present study was to isolate and characterize hydrophobins from a gushing-active fungus, Fusarium graminearum (teleomorph...
