Translocation of secreted effector proteins from fungal pathogens into host plant cells. Every year, fungal diseases of plants cause huge losses in agricultural productivity and extensive environmental damage in Australia. Disease control in major crops, like wheat, currently relies heavily on breeding for disease resistance. However, fungal pathogens continually adapt to overcome plant defences, necessitating identification of new sources of resistance. The research in this project will eluc ....Translocation of secreted effector proteins from fungal pathogens into host plant cells. Every year, fungal diseases of plants cause huge losses in agricultural productivity and extensive environmental damage in Australia. Disease control in major crops, like wheat, currently relies heavily on breeding for disease resistance. However, fungal pathogens continually adapt to overcome plant defences, necessitating identification of new sources of resistance. The research in this project will elucidate the molecular basis of a new aspect of the establishment of plant infection by fungi, and in so doing will provide new avenues for the development of novel disease resistance strategies, with relevance in particular to devastating cereal diseases like wheat rust.Read moreRead less
Role of fungal secreted proteins as plant disease effectors. Many crop diseases are economically significant threats to agricultural productivity in Australia, with rust fungi in particular being a major problem for cereal grain production. Current methods of rust disease control are based on breeding for resistance but continued adaption by rust fungi to overcome plant defences means there is an urgent need for new methods of crop protection. This project will investigate molecular processes ....Role of fungal secreted proteins as plant disease effectors. Many crop diseases are economically significant threats to agricultural productivity in Australia, with rust fungi in particular being a major problem for cereal grain production. Current methods of rust disease control are based on breeding for resistance but continued adaption by rust fungi to overcome plant defences means there is an urgent need for new methods of crop protection. This project will investigate molecular processes underlying fungal infection of plants, focusing on mechanisms that enable fungi to take over the metabolism of infected cells. The research will provide basic knowledge for development of novel and durable disease resistance strategies.Read moreRead less
Preparation of Photo-Affinity Molecular Probes for the Identification of Gibberellin Receptors. Bioactive gibberellins affect numerous processes during plant growth and development, including seed germination, leaf expansion, stem elongation, flowering and fruit development. However, only very limited information is available regarding their mode of action at the molecular level. The central aim of the project is to prepare a family of photo-affinity molecular probes based on the gibberellin m ....Preparation of Photo-Affinity Molecular Probes for the Identification of Gibberellin Receptors. Bioactive gibberellins affect numerous processes during plant growth and development, including seed germination, leaf expansion, stem elongation, flowering and fruit development. However, only very limited information is available regarding their mode of action at the molecular level. The central aim of the project is to prepare a family of photo-affinity molecular probes based on the gibberellin molecule that will be designed to provide critical information on the location and structure of gibberellin receptors. Screening of the probes for potential effectiveness will be determined initially by the measurement of alpha-amylase produced in a standard barley aleurone assay.Read moreRead less
