1. Métodos de inoculação e agressividade de cinco espécies de Fusarium à pupunheira
RESUMO: A fusariose é uma das principais doenças da pupunheira (Bactris gasipaes Kunth.var gasipaes Henderson). O objetivo deste trabalho foi avaliar métodos de inoculação e a agressividade de isolados de cinco espécies de Fusarium à pupunheira. Demonstrou-se que Fusarium proliferatum pode infectar folhas, caule e raízes de pupunheira. Verificou-se q

2. First report and characterization of Fusarium circinatum, the causal agent of pitch canker in Brazil
Pitch canker is one of the most important diseases of pine trees worldwide, including South America. The causal agent of this disease is Fusarium circinatum, a member of the Gibberella fujikuroi complex (GFC). In South America, the species is reported from Colombia, Uruguay and Chile, but is considered a quarantine organism in Brazil. In this study we charac

3. Fusarium species and fumonisins associated with maize kernels produced in Rio Grande do Sul State for the 2008/09 and 2009/10 growing seasons
Ear rots caused by Fusarium spp. are among the main fungal diseases that contribute to poor quality and the contamination of maize grains with mycotoxins. This study aimed to determine the visual incidence of fungal-damaged kernels (FDKs), the incidence of two main Gibberella (a teleomorph of Fusarium) complexes (G. fujikuroi and G. zeae) associated with mai

4. Prevalência, perfil toxigênico e agressividade de espécies de Fusarium associadas aos grãos de milho do Estado do Rio Grande do Sul / Prevalence, toxigenic profile and aggressiveness of fusarium species associated with corn kernels from Rio Grande Do Sul state
The increasing concern to mycotoxins in maize kernels is related to a frequent occurrence of epidemics of ear rot of corn caused by Fusarium spp in Brazil. This study aimed to: 1) assess the incidence of Fusarium spp. and determine fumonisin levels in maize samples (harvest seasons 2009 and 2010) from several municipalities of the Rio Grande do Sul state, Br

5. Diversidade genética de isolados do agente etiológico da fusariose do abacaxizeiro no Brasil / Genetic diversity of strains of pineapples fusariose etiologic agent in Brazil
Com o objetivo de conhecer a diversidade genética existente na população de Fusarium guttiforme, agente etiológico da resinose ou fusariose do abacaxizeiro, foram realizadas análises de VCG, AFLP e caracterização morfológica em isolados de F. guttiforme provenientes de diferentes estados brasileiros. Todos os 130 isolados avaliados apresentaram os ma

6. PCR-Based Identification of MAT-1 and MAT-2 in the Gibberella fujikuroi Species Complex†
All sexually fertile strains in the Gibberella fujikuroi species complex are heterothallic, with individual mating types conferred by the broadly conserved ascomycete idiomorphs MAT-1 and MAT-2. We sequenced both alleles from all eight mating populations, developed a multiplex PCR technique to distinguish these idiomorphs, and tested it with representative s

7. Molecular Standardization of Mating Type Terminology in the Gibberella fujikuroi Species Complex†
Mating type in the Gibberella fujikuroi species complex is controlled by a single locus with two alleles and is usually identified following sexual crosses with standard, female-fertile tester isolates. The mating type alleles have been arbitrarily designated “+” and “−” within each biological species, and the nomenclature is tied to the standard t

8. Fusarium subglutinans f. sp. pini Represents a Distinct Mating Population in the Gibberella fujikuroi Species Complex†
Fusarium strains in the Gibberella fujikuroi species complex cause diseases on a variety of economically important plants. One of these diseases, pitch canker of Pinus spp., is caused by strains identified as Fusarium subglutinans f. sp. pini. Fertile crosses were detected between F. subglutinans f. sp. pini strains from South Africa, California, and Florida

9. Fusarium Species from Nepalese Rice and Production of Mycotoxins and Gibberellic Acid by Selected Species
Infection of cereal grains with Fusarium species can cause contamination with mycotoxins that affect human and animal health. To determine the potential for mycotoxin contamination, we isolated Fusarium species from samples of rice seeds that were collected in 1997 on farms in the foothills of the Nepal Himalaya. The predominant Fusarium species in surface-d

10. Differentiation of Fusarium subglutinans f. sp. pini by Histone Gene Sequence Data
Fusarium subglutinans f. sp. pini (= F. circinatum) is a pathogen of pine and is one of eight mating populations (i.e., biological species) in the Gibberella fujikuroi species complex. This species complex includes F. thapsinum, F. moniliforme (= F. verticillioides), F. nygamai, and F. proliferatum, as well as F. subglutinans associated with sugarcane, maize

11. Species Diversity of and Toxin Production by Gibberella fujikuroi Species Complex Strains Isolated from Native Prairie Grasses in Kansas†
Fusarium species from agricultural crops have been well studied with respect to toxin production and genetic diversity, while similar studies of communities from nonagricultural plants are much more limited. We examined 72 Fusarium isolates from a native North American tallgrass prairie and found that Gibberella intermedia (Fusarium proliferatum), Gibberella

12. Production of fusaric acid by Fusarium species.
Fusaric acid is a mycotoxin with low to moderate toxicity, which is of concern since it might be synergistic with other cooccurring mycotoxins. Fusaric acid is widespread on corn and corn-based food and feeds and is frequently found in grain, where Fusarium spp. are also isolated. We surveyed 78 strains of Fusarium moniliforme, F. crookwellense, F. subglutin
