Biography

Dr Dodds' research focuses on fungal rust diseases of plants, which constitute one of the most significant threats to cereal crops worldwide. The recent emergence and spread of highly virulent wheat stem rust strains in Africa, including Ug99, is of particular concern to world food security.
Dr Dodds' has used the pathogenic interaction between flax and the flax rust fungus as a model for understanding the basis of rust disease as well as host resistance mechanisms. Resistance to rust disease is governed by the gene-for-gene model, where resistance depends on an interaction between host resistance (R) genes pathogen avirulence (Avr) genes.
Host R proteins constitute the recognition components of the plant innate immunity system and function to recognise specific proteins produced by the pathogen, the Avr proteins, and then induce a localised defence response that prevents infection.
Our work in the model flax rust system identified rust Avr proteins as members of a class of small secreted proteins that are translocated into host cells during infection as disease effectors that promote infection. We have corroborated these observations in cereal rusts through the identification of numerous resistance proteins from wheat and recently the first Avr genes from wheat stem rust, Puccinia graminis fsp tritici.
Current work in the group focuses on:
• molecular basis of recognition of rust Avr proteins by plant R proteins
• the mechanism of R protein activation and signalling in model and crop plants
• improving resistance breeding in wheat through DNA markers for R genes
• identification of wheat stem rust Avr genes
• the mechanism of translocation of rust effector proteins into plant cells
• functions of rust effectors in disease.
