A large number of Fusarium isolates closely related to F. subglutinans were collected from maize in Belgium. We used a robust polyphasic approach to describe a new biological species, Fusarium temperatum, within the Gibberella fujikuroi species complex. F. temperatum can be distinguished from F. subglutinans and from other Fusarium species within the Gibberella fujikuroi species complex with AFLP fingerprint profile, differences in the translation elongation factor 1-α and β-tubulin DNA… 

Fusarium temperatum and Fusarium subglutinans isolated from maize in Argentina.

Fusarium temperatum isolated from maize in France

The phylogenetic analysis showed that the two species isolated from infected maize ears represented two clades strongly supported by bootstrap values, and the pathogenicity of F. temperatum strains was confirmed on maize ears.

Polyphasic Approach Used for Distinguishing Fusarium temperatum from Fusarium subglutinans

In situ detached barley leaf assay and artificially stalk and ear inoculation of two maize hybrids demonstrated that both F. temperatum and F. subglutinans strains were medium and strong pathogens under laboratory and field conditions, respectively.

Two new species of the Fusarium fujikuroi species complex isolated from the natural environment

Fusarium sudanense and Fusarium terricola are introduced as novel species in the F. fujikuroi species complex based on phenotypic, physiological characters and molecular data.

Molecular diversity of the Fusarium fujikuroi species complex from maize

Random amplified polymorphic DNA markers were used to estimate genetic relationship and diversity of Fusarium species associated with pink ear rot of maize and demonstrated that although F. temperatum and F. subglutinans s.s. form two distinct groups they are more similar to each other than to F. verticillioides.

Occurrence, Pathogenicity, and Mycotoxin Production of Fusarium temperatum in Relation to Other Fusarium Species on Maize in Germany

A monitoring of maize ears and stalks in Germany demonstrated a higher prevalence and aggressiveness of F. temperatum compared to F. subglutinans in German maize cultivation areas, and pathogenic on wheat and capable to cause moderate to severe head blight symptoms.

Molecular Identification, Mycotoxin Production and Comparative Pathogenicity of Fusarium temperatum Isolated from Maize in China

Morphological and molecular phylogenetic analyses based on the DNA sequences of individual translation elongation factor 1-alpha and β-tubulin genes revealed that the recovered isolates produced macroconidia typical of four-septate with a foot-shaped basal cell and belonged to F. temperatum that is distinctly different from its most closely related species F.–subglutinans.

Response of maize genotypes to the infection by selected Fusarium isolates from Liseola section

Based on the results obtained from the carried out studies, it can be concluded that F. temperatum could be more aggressive than other species from Liseola section.

Fusarium subglutinans f. sp.pini Represents a Distinct Mating Population in theGibberella fujikuroi Species Complex

It is concluded that fertile F. pini isolates represent a new mating population (mating population H) of G. fujikuroi and that they belong to a unique biological species in a distinct taxon.

Cryptic speciation in Fusarium subglutinans

Fusarium isolates belonging to the E-mating population that were collected from either maize or teosinte, from a wide geographic range revealed the presence of two major groups representing cryptic species in F. subglutinans, which suggests not only that the existing F.SubglUTinans populations are in the process of divergence, but also that each of the resulting lineages are undergoing separation into distinct taxa.

Gibberella konza (Fusarium konzum) sp. nov. from prairie grasses, a new species in the Gibberella fujikuroi species complex.

A new species, Gibberella konza (Gibberella fujikuroi mating population I [MP-I]), is described from native prairie grasses in Kansas and although female fertility for field isolates of this species appears to be low, G. konzo is heterothallic, and reliably female fertile mating population tester strains for this species are developed.

Differentiation of Fusarium subglutinansf. sp. pini by Histone Gene Sequence Data

A PCR-restriction fragment length polymorphism technique is developed that reliably distinguishes F. pini from other isolates identified as F. subglutinans from the other biological species in the G. fujikuroi species complex.

Gibberella fujikuroi mating population E is associated with maize and teosinte.

Phylogenetic analyses and comparison with sequences from public domain databases indicated that the F. subglutinans isolates from teosinte are most closely related to strains of G. fujikuroi mating population E, and the putative mating population from the wild relatives of maize therefore forms part of the existing E-mating population and does not constitute a new lineage in the G.fujik Kuroi species complex.
