Biogeography and phylogeography of Fusarium: a review

Fusarium is a large, complex genus that causes a wide variety of plant diseases, produces a number of mycotoxins and is becoming increasingly recognized as a significant human pathogen. These fungi occur in ecosystems in all parts of the globe, which makes them useful as a model to better understand biogeographic processes affecting the distribution of fungi. Here we review the information available on the biogeography of different species and clades of Fusarium and some of the likely processes affecting dispersal and speciation.
