Abstract:

Gibberella zeae, Fusarium verticillioides and F. subglutinans are the most important causes of Fusarium stalk rot in corn (Zea mays L.). Gibberella zeae also causes fusarium head blight in wheat (Triticum aestivum L.) and gibberella ear rot in corn. The objectives of this study were to investigate prevalence of Fusarium species in the stalks of seed corn over time and to investigate the influence of sampling time and internode position on Fusarium spp. and G. zeae, particularly. Fusarium subglutinans and G. zeae were the most frequently recovered species from asymptomatic host tissue and from

Abstract:

ABSTRACT The ascomycete fungus Gibberella zeae is an important plant pathogen that causes fusarium head blight on small grains. Molecular studies of this fungus have been performed extensively to uncover the biological mechanisms related to pathogenicity, toxin production, and sexual reproduction. Molecular methods, such as targeted gene deletion, gene overexpression, and gene fusion to green fluorescent protein (GFP), are relatively easy to perform with this fungus; however, conditional expression systems have not been developed. The purpose of this study was to identify a promoter that could

Abstract:

We developed a method for inducing sexual outcrosses in the homothallic Ascomycete fungus Gibberella zeae (anamorph: Fusarium graminearum). Strains were marked with different nitrate nonutilizing (nit) mutations, and vegetative compatibility groups served as additional markers in some crosses. Strains with complementary nit mutations were cocultured on carrot agar plates. Ascospores from individual perithecia were plated on a minimal medium (MM) containing nitrate as the sole nitrogen source. Crosses between different nit mutants segregated in expected ratios (3:1 nit-:nit+) from heterozygous

Gibberella zeae, causal agent of Fusarium head blight (FHB) of wheat and barley and Gibberella ear rot (GER) of corn, may be transported over long distances in the atmosphere. Epidemics of FHB and GER may be initiated by regional atmospheric sources of inoculum of G. zeae; however, little is known about the origin of inoculum for these epidemics. We tested the hypothesis that atmospheric populations of G. zeae are genetically diverse by determining the genetic structure of New York atmospheric populations (NYAPs) of G. zeae, and comparing them with populations of G. zeae collected from seven d

Abstract:

ABSTRACT Zearalenone, a mycotoxin produced by several Fusarium spp., is most commonly found as a contaminant in stored grain and has chronic estrogenic effects on mammals. Zearalenone is a polyketide derived from the sequential condensation of multiple acetate units by a polyketide synthase (PKS), but the genetics of its biosynthesis are not understood. We cloned two genes, designated ZEA1 and ZEA2, which encode polyketide synthases that participate in the biosynthesis of zearalenone by Gibberella zeae (anamorph Fusarium graminearum). Disruption of either gene resulted in the loss of zearaleno

Gibberella zeae causes Fusarium head blight (FHB) of wheat and barley and Gibberella ear rot (GER) of corn. Ascospores of G. zeae rely on atmospheric motion systems for transport to susceptible host plants. A long term objective of our research is to determine where inoculum for FHB and GER comes from and how far it travels. We measured the distance that ascospores of G. zeae were forcibly discharged in still air, and determined that long-range transport is favored by day-time ascospore release. We used remote-piloted aircraft to collect viable spores of G. zeae in the lower atmosphere. Viable

Os danos na redução do rendimento de grãos, causados pela infecção natural de giberela no campo, foram quantificados em diferentes cultivares de trigo nas safras agrícolas de 2001 e 2002, no município de Passo Fundo, RS. Do estádio de grão leitoso até a maturação, foram identificadas e marcadas todas as espigas de trigo gibereladas,

ABSTRACT We previously published a genetic map of Gibberella zeae (Fusarium graminearum sensu lato) based on a cross between Kansas strain Z-3639 (lineage 7) and Japanese strain R-5470 (lineage 6). In this study, that genetic map was aligned with the third assembly of the genomic sequence of G. zeae strain PH-1 (lineage 7) using seven structural genes and 108 sequenced amplified fragment length polymorphism markers. Several linkage groups were combined based on the alignments, the nine original linkage groups were reduced to six groups, and the total size of the genetic map was reduced from 1,

Abstract:

Sensitivity of Gibberella zeae to carbendazim was determined by measuring mycelial growth in fungicide-amended media. Among 1,529 isolates tested, 31 isolates showed a high level of resistance (HR) to carbendazim (fungicide concentration that results in 50% inhibition of mycelial growth [EC50] of 10.35 to 30.26 mg a.i. liter–1) and 10 isolates were moderately resistant (MR) (EC50 of 4.50 to 7.28 mg a.i. liter–1). The remaining 1,488 isolates were sensitive to carbendazim and were unable to grow on potato dextrose agar amended with carbendazim at 2 mg a.i. liter–1. Analysis of DNA sequences of

ABSTRACT Connections between fungal development and secondary metabolism have been reported previously, but as yet, no comprehensive analysis of a family of secondary metabolites and their possible role in fungal development has been reported. In the present study, mutant strains of the heterothallic ascomycete Cochliobolus heterostrophus, each lacking one of 12 genes (NPS1 to NPS12) encoding a nonribosomal peptide synthetase (NRPS), were examined for a role in sexual development. One type of strain (Δnps2) was defective in ascus/ascospore development in homozygous Δnps2 crosses. Homozygous cr

Abstract:

ABSTRACT The glyoxylate and methylcitrate cycles are involved in the metabolism of two- or three-carbon compounds in fungi. To elucidate the role(s) of these pathways in Gibberella zeae, which causes head blight in cereal crops, we focused on the functions of G. zeae orthologs (GzICL 1 and GzMCL1) of the genes that encode isocitrate lyase (ICL) and methylisocitrate lyase (MCL), respectively, key enzymes in each cycle. The deletion of GzICL1 (ΔGzICL1) caused defects in growth on acetate and in perithecium (sexual fruiting body) formation but not in virulence on barley and wheat, indicating that

Gibberella zeae incites Fusarium head blight (FHB), a devastating disease that causes extensive yield and quality losses to wheat and barley. Of over 700 microbial strains obtained from wheat anthers, 54 were able to utilize tartaric acid as a carbon source when the compound was supplied as choline bitartrate in liquid culture. Four tartaric acid-utilizing and three nonutilizing strains reduced FHB in initial tests and were selected for further assays. Antagonists were effective against three different isolates of G. zeae when single wheat florets were inoculated with pathogen and antagonist i

Abstract:

Gibberella zeae, a causal agent of Fusarium head blight (FHB) in wheat and barley, is one of the most economically harmful pathogens of cereals in the United States. In recent years, the known host range of G. zeae has also expanded to noncereal crops. However, there is a lack of information on the population genetic structure of G. zeae associated with noncereal crops and across wheat cultivars. To test the hypothesis that G. zeae populations sampled from barley, wheat, potato, and sugar beet in the Upper Midwest of the United States are not mixtures of species or G. zeae clades, we analyzed

Abstract:

ABSTRACT In heterothallic ascomycete fungi, idiomorphic alleles at the MAT locus control two sex pheromone-receptor pairs that function in the recognition and chemoattraction of strains with opposite mating types. In the ascomycete Gibberella zeae, the MAT locus is rearranged such that both alleles are adjacent on the same chromosome. Strains of G. zeae are self-fertile but can outcross facultatively. Our objective was to determine if pheromones retain a role in sexual reproduction in this homothallic fungus. Putative pheromone precursor genes (ppg1 and ppg2) and their corresponding pheromone

Abstract:

The potential of Microsphaeropsis sp. (isolate P130A) as an antagonist of Gibberella zeae was tested under in vitro and field conditions. Firstly, an in vitro method of ascospore production was developed on wheat and corn residues. The plant type (corn or wheat), residue type (straw/stalk or grain), and incubation conditions (closed or open) had a significant effect on ascospore production. Perithecia were more abundant on wheat and corn grain incubated under open conditions. On these two substrates, the application of Microsphaeropsis sp. significantly reduced ascospore production.
