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

Abstract

Two new species in the Fusarium fujikuroi species complex (FFSC) are introduced. One of these, represented by strain CBS 454.97 was isolated from plant debris (Striga hermonthica) in the Sudan, while the second, represented by strains CBS 119850 and CBS 483.94, which originated from soil in Australia. Molecular analyses were performed including TEF1 spanning 576 bp region, 860 bp region of rPB2, and 500 bp BT2 region. Phylogenetic trees based on these regions showed that the two species are clearly distinct from all known taxa in the F. fujikuroi species complex. Based on phenotypic, physiological characters and molecular data, we introduce Fusarium sudanense and Fusarium terricola as novel species in the complex.

Endohyphal bacteria associated with virulence, increased expression of fumonisin biosynthetic genes, and production of fumonisin and macroconidia in Fusarium fujikuroi W343

“…The genus also includes mycotoxin producers that cause the contamination of cereal grains and other agricultural products, which can result in adverse human and animal health conditions (Kvas et al , ). Members of the Gibberella fujikuroi species complex (GFSC) include more than 45 phylogenetic species, 10 biological and morphological species, 34 morphospecies (Moussa et al , ), and more than nine mating populations (Leslie & Summerell, ). Fusarium fujikuroi , which belongs to mating population C (MP‐C) (Leslie & Summerell, ), infects and causes disease in several crops including ear and root rot of corn (Leyva‐Madrigal et al , ), bakanae or foolish seedling disease in rice (Desjardins et al , ; Carter et al , ) and grapevine (Bolton et al , ).…”

Genomic sequencing of the aquaticFusariumspp. QHM and BWC1 and their potential application in environmental protection

“…Species of the genus Fusarium are an important group of fungi that are distributed widely in below-ground and above-ground habitats (1, 2). Certain Fusarium species can even be found in aquatic habitats, including coal mine pits and subterranean rivers (2). These species are also characterized by their ability to grow in environments with a wide pH range (1, 2).…”

“…Certain Fusarium species can even be found in aquatic habitats, including coal mine pits and subterranean rivers (2). These species are also characterized by their ability to grow in environments with a wide pH range (1, 2). The genus Fusarium is important from the perspective of environmental protection and phytopathogenicity: On the one hand, Fusarium spp.…”

“…Given the complex characteristics of these species, it is imperative to elucidate the Fusarium genome sequence for the elimination of pollutants while ensuring the control of its pathogenicity. Further, as the Fusarium genus forms a “species complex” with the Aspergillus genus on account of closely related species, species-level identification of Fusarium is also necessary (4). Whole-genome sequencing would be ideal, as this method provides more information than other sequencing approaches in terms of the elucidation of acidic mechanisms, biodegradation and microbial identification.…”

Identification of Fusarium species as putative mycoparasites of Plasmopara viticola causing downy mildew in grapevines

“…Bootstrap confidence intervals were set at 50% (Saitou and Nei 1987). For phylogenetic analysis recent research papers based on the phylogeny of Fusarium were used (Moussa et al 2017;Laurence et al 2015;Al-Hatmi et al 2016;Lombard et al 2015;Herron et al 2015;O'Donnell et al 2009;Schroers et al 2009;O'Donnell et al 2004O'Donnell et al , 2008. The internal transcribed spacer (ITS) and tef-1α genes BLASTn results for five Fusarium isolates is compiled in Table 1.…”
