About my Ph.D:

Fusarium and the Poaceae

Anyone who knows anything about Fusarium will know that this group of fungi is associated with a wide variety of plants, including the grasses (Poaceae). The relationship between grasses and Fusarium is well-known, having evolved over millions of years. The more important fusaria are those that cause disease on commercially important cereals and are well-studied. Many of these studies also look at the role of 'wild' grasses in these systems as alternative hosts for future infections.

It makes sense that a grass Fusarium causing disease on wheat would be found on a wild relative of wheat or a close grass relative, but what about Fusarium species causing disease on woody hosts? Fusarium circinatum, the pitch canker fungus, is a pathogen of Pinus. This pathogen was thought to only infect pine; however, a recent study reported that this pine pathogen could be isolated from wild grass growing in the understory of pitch canker infected Pinus radiata.  A couple years after this study, F. circinatum was reported from another five grass species, including maize.

It is a rarity to find a Fusarium pathogen of woody plants on a grass host. Since 2001, only three species of Fusarium have been found on both grass and a woody plant, two of these belong to the Fusarium graminearum species complex — notorious for grass associated fusaria. F. circinatum belongs to the Fusarium fukikuroi species complex (FFSC) that also encompasses some grass associates.

My PhD will look at the role grasses play as alternative hosts for Fusarium and establish the relative importance of this overlooked and underrated group of plants as alternative hosts for some of the world's most important Fusarium pathogens of woody plants.
