Thesis Title
Identification and characterization of Dothistroma septosporum effectors

Read article at Massey Research Online:

Dothistroma needle blight, caused by the fungus聽Dothistroma septosporum, is a major pest of pine species. Outbreaks of the disease cause extensive defoliation and mortality in plantations of pine. To understand the molecular cross-talk between聽Dothistroma septosporum聽and pine, Mrs Guo identified and characterised several effector genes (factors that facilitate pathogen invasion) from the聽Dothistroma septosporum聽New Zealand genome. She investigated聽in planta聽expression of those effectors during disease progression, polymorphism of those effectors in a global collection of聽Dothistroma septosporum聽strains and tested if those effectors are virulence factors when infecting聽pinus radiata. Her results provide screening tools for pine resistant germplasm. Eventually this could lead to knowledge of plant susceptibility and/or resistance genes that could be exploited in future breeding programmes.
