Identification of immune receptor and signalling proteins from plants. This project aims to clone a new extracellular pathogen receptor, and map immune signalling pathways downstream of both intra- and extra-cellular receptors using innovative biochemical methods. The plant immune system protects plants and crops from attack by pests and pathogens. It is an innate system based on extracellular and intracellular pathogen receptors. Despite the importance of plant immunity in both biological and a ....Identification of immune receptor and signalling proteins from plants. This project aims to clone a new extracellular pathogen receptor, and map immune signalling pathways downstream of both intra- and extra-cellular receptors using innovative biochemical methods. The plant immune system protects plants and crops from attack by pests and pathogens. It is an innate system based on extracellular and intracellular pathogen receptors. Despite the importance of plant immunity in both biological and agricultural terms, little is known about the identity of such receptors or the signalling events that link pathogen perception to response. The results are expected to enhance crop productivity and provide important insights into the architecture of the plant immune system.Read moreRead less
Improving plant reproductive success under heat stress: A sweet approach. This project aims to determine how genetic manipulation of cell wall invertase (CWIN) activity could regulate pollen germination, elongation and fruit set under heat stress using tomato as a model. Plant reproductive processes are highly susceptible to heat stress, which often leads to pollination failure and fruit and seed abortion, hence irreversible yield loss. Research has established that CWIN-mediated sugar metabolis ....Improving plant reproductive success under heat stress: A sweet approach. This project aims to determine how genetic manipulation of cell wall invertase (CWIN) activity could regulate pollen germination, elongation and fruit set under heat stress using tomato as a model. Plant reproductive processes are highly susceptible to heat stress, which often leads to pollination failure and fruit and seed abortion, hence irreversible yield loss. Research has established that CWIN-mediated sugar metabolism and signaling may play crucial roles in pollen growth and fruit set under heat stress. The intended outcome is the generation of critical knowledge that will advance understanding on reproductive development under heat stress, thereby providing significant benefits, such as novel ideas and solutions for improving crop yield.Read moreRead less
Unique plant hormone responses: the key to nitrogen-fixing nodules. This project aims to build a model of the signals that regulate root nodule formation, unique root organs formed by some plants that host nitrogen-fixing bacteria. Nitrogen is often limited in the soil and agriculture relies on nitrogen fertiliser. Sustainable sources of plant nutrients are required to ensure food security and minimise the environmental impact of intensive farming. This project will provide fundamental informati ....Unique plant hormone responses: the key to nitrogen-fixing nodules. This project aims to build a model of the signals that regulate root nodule formation, unique root organs formed by some plants that host nitrogen-fixing bacteria. Nitrogen is often limited in the soil and agriculture relies on nitrogen fertiliser. Sustainable sources of plant nutrients are required to ensure food security and minimise the environmental impact of intensive farming. This project will provide fundamental information on why some species can form nitrogen-fixing nodules by examining the role of plant hormones. This will build the knowledge base required to potentially expand this symbiosis into non-legumes, harnessing the huge advantage nodule forming species have in staple crops.Read moreRead less
Molecular characterisation of the Prf bacterial recognition complex of tomato. This project will investigate the composition and function of a large protein complex in tomatoes that controls their ability to resist attack by bacteria. The results will provide understanding to how all plants resist all diseases, and may help to improve environmentally-benign disease resistance in crop species.
