Fusarium commune is a new species identified by morphological and molecular phylogenetic data
Skovgaard, Kerstin | Rosendahl, Søren | O'Donnell, Kerry | Nirenberg, Helgard I.
Fusarium commune sp. nov. was isolated from soil and Pisum sativum in Denmark and several widespread locations within the northern hemisphere from diverse substrates including white pine, Douglas fir, carnation, corn, carrot, barley and soil. Fusarium commune is characterized by and distinguished from its putative sister taxon, the F. oxysporum complex, in having long, slender monophialides and polyphialides when cultured in the dark. Based on the combined DNA sequence data from translation elongation factor 1α (EF-1α) and the mitochondrial small subunit ribosomal DNA (mtSSU rDNA), the 15 isolates of F. commune analyzed formed a strongly supported clade closely related to but independent of the F. oxysporum and Gibberella fujikuroi species complexes.
