Solomon Group - Wheat biosecurity

Fungal diseases are the cause of millions of tonnes in yield losses each on farms around the world. This is serious issue not only in terms of financial losses, but also when considering food security and stability. Using today's wheat prices, the losses from fungi in Australia exceed $1 billion dollars, and that is using effective control measures; without these losses would exceed $5 billion dollars.Thus there are many good reasons to better understand how these pathogens cause disease! Our laboratory focuses on two significant pathogens of wheat, Parastagonospora nodorum and Zymoseptoria tritici. Read more about it on my research page.

PS Seminar Series- PhD Exit seminar - Characterising extracellular vesicles from the fungal wheat pathogen Zymoseptoria tritici

Event | Fri 10 February 2023
Fungal phytopathogens secrete a litany of molecules during their infection of a plant host, including virulence factors like effector proteins. Secreted virulence factors function in the apoplast of host tissues or are trafficked into host cells.
