Jiang Tan, Maarten Ameye, Sofie Landschoot, Noémie De Zutter, more

Molecular Plant Pathology > 21 > 12 > 1559 - 1572

Plant diseases are often caused by a consortium of pathogens competing with one another to gain a foothold in the infection niche. Nevertheless, studies are often limited to a single pathogen on its host. In Europe, fusarium head blight (FHB) of wheat is caused by multiple Fusarium species, including Fusarium graminearum and F. poae. Here, we combined a time series of (co)inoculations, monitored by...

Living apart together: crosstalk between the core and supernumerary genomes in a fungal plant pathogen

Adriaan Vanheule, Kris Audenaert, Sven Warris, Henri van de Geest, more

BMC Genomics > 2016 > 17 > 1 > 1-18

Background Eukaryotes display remarkable genome plasticity, which can include supernumerary chromosomes that differ markedly from the core chromosomes. Despite the widespread occurrence of supernumerary chromosomes in fungi, their origin, relation to the core genome and the reason for their divergent characteristics are still largely unknown. The complexity of genome assembly due to the presence of...

Anne D. Diepeningen, Balázs Brankovics, Jearidienne Iltes, Theo A. J. van der Lee, more

Current Fungal Infection Reports > 2015 > 9 > 3 > 135-143

Infections caused by the genus Fusarium have emerged over the past decades and range from onychomycosis and keratitis in healthy individuals to deep and disseminated infections with high mortality rates in immune-compromised patients. As antifungal susceptibility can differ between the different Fusarium species, identification at species level is recommended. Several clinical observations as hyaline...

Relocation of genes generates non-conserved chromosomal segments in Fusarium graminearum that show distinct and co-regulated gene expression patterns

Chunzhao Zhao, Cees Waalwijk, Pierre Jgm de Wit, Dingzhong Tang, more

BMC Genomics > 2014 > 15 > 1 > 1-17

Background Genome comparisons between closely related species often show non-conserved regions across chromosomes. Some of them are located in specific regions of chromosomes and some are even confined to one or more entire chromosomes. The origin and biological relevance of these non-conserved regions are still largely unknown. Here we used the genome of Fusarium graminearum to elucidate the significance...

Birth, death and horizontal transfer of the fumonisin biosynthetic gene cluster during the evolutionary diversification of Fusarium

Robert H. Proctor, François Van Hove, Antonia Susca, Gaetano Stea, more

Molecular Microbiology > 90 > 2 > 290 - 306

Fumonisins are a family of carcinogenic secondary metabolites produced by members of the Fusarium fujikuroi species complex (FFSC) and rare strains of Fusarium oxysporum. In Fusarium, fumonisin biosynthetic genes (FUM) are clustered, and the cluster is uniform in gene organization. Here, sequence analyses indicated that the cluster exists in five different genomic contexts, defining five cluster types...

Simultaneous real-time PCR detection of Fusarium asiaticum, F. ussurianum and F. vorosii, representing the Asian clade of the F. graminearum species complex

Dolores Fernández-Ortuño, Cees Waalwijk, Theo Van der Lee, Jieru Fan, more

International Journal of Food Microbiology > 2013 > 166 > 1 > 148-154

Due to the repeated discovery of new members of the Fusarium graminearum species complex (FGSC), some of the F. graminearum sensu stricto (s.s.)-specific qPCR assays developed to date have since been shown to be non-specific. In this study, a probe-based qPCR method was developed, targeting a sterol 14-alpha demethylase (CYP51) paralogue, CYP51C unique to the genus Fusarium, for the simultaneous detection...

The genetic basis for 3-ADON and 15-ADON trichothecene chemotypes in Fusarium

Nancy J. Alexander, Susan P. McCormick, Cees Waalwijk, Theo van der Lee, more

Fungal Genetics and Biology > 2011 > 48 > 5 > 485-495

Certain Fusarium species cause head blight of wheat and other small grains worldwide and produce trichothecene mycotoxins. These mycotoxins can induce toxicoses in animals and humans and can contribute to the ability of some fusaria to cause plant disease. Production of the trichothecene 3-acetyldeoxynivalenol (3-ADON) versus 15-acetyldeoxynivalenol (15-ADON) is an important phenotypic difference...
