Oxygen Signalling in Grapevine Bud Dormancy. Dormancy is an important economic and ecological trait of many trees and crop plants, including most commercially valuable fruit species. This project aims to: define oxygen and radicals of oxygen as central cues of grapevine bud development and dormancy; identify and model the developmental processes that occur during dormancy onset, maintenance and release (bud burst); as well as to identify the molecular and biochemical regulators of oxygen signals ....Oxygen Signalling in Grapevine Bud Dormancy. Dormancy is an important economic and ecological trait of many trees and crop plants, including most commercially valuable fruit species. This project aims to: define oxygen and radicals of oxygen as central cues of grapevine bud development and dormancy; identify and model the developmental processes that occur during dormancy onset, maintenance and release (bud burst); as well as to identify the molecular and biochemical regulators of oxygen signals in bud dormancy. The knowledge generated could provide a platform to test impacts of climate change on fruit and tree species, and lead to better management of fruit and tree species in agricultural and ecological systems.Read moreRead less
Developmental functions of oxygen and redox cues in plants. This project aims to transform our understanding of the regulation of meristem functions, with a central hypothesis that plant cell quiescence (repressed cell division) is governed by oxygen and oxidation/reduction (redox)-dependent cues. Meristems are the growing tips of plants, and thus the fundamental unit of plant growth and productivity. This project will develop new knowledge of how plants integrate changes in the environment to r ....Developmental functions of oxygen and redox cues in plants. This project aims to transform our understanding of the regulation of meristem functions, with a central hypothesis that plant cell quiescence (repressed cell division) is governed by oxygen and oxidation/reduction (redox)-dependent cues. Meristems are the growing tips of plants, and thus the fundamental unit of plant growth and productivity. This project will develop new knowledge of how plants integrate changes in the environment to regulate meristem activity. This project will define new paradigms of how oxygen and redox status interact with energy and other cues to regulate decisions to grow or quiesce. This will underpin the development of new strategies to optimise crop management and productivity, improve the efficiency of inputs, and reduce the risk of decision making in crop production.Read moreRead less
Unlocking a new hormone signalling system to increase plant performance. This project seeks to discover new ways to improve crop productivity by investigating a recently identified chemical signalling pathway in plants that affects seed germination, seedling growth, leaf development and water use. The aims are to identify unknown signalling compounds that work through this pathway, to discover the molecular regulators of the pathway, and to examine how it operates in different plant species. The ....Unlocking a new hormone signalling system to increase plant performance. This project seeks to discover new ways to improve crop productivity by investigating a recently identified chemical signalling pathway in plants that affects seed germination, seedling growth, leaf development and water use. The aims are to identify unknown signalling compounds that work through this pathway, to discover the molecular regulators of the pathway, and to examine how it operates in different plant species. The project also plans to exploit this pathway to find inhibitors of premature seed germination that afflict crops such as wheat and barley. The intended outcomes are a better understanding of how plants grow and new strategies for boosting plant performance in the field. Specific potential applications include reducing plant water use, regulating seed germination, and encouraging early seedling establishment. Read moreRead less
Understanding the biological functions of the karrikin-responsive signaling system of plants in growth, development and responses to the environment. A new signalling system in plants, related to that of strigolactone hormones but evolutionarily more ancient and functionally distinct, has been discovered. It is defined by the Karrkin-Insensitive-2 (KAI2) protein discovered by its ability to confer responsiveness to karrikins from bushfires. The KAI2 system influences seed germination, and develo ....Understanding the biological functions of the karrikin-responsive signaling system of plants in growth, development and responses to the environment. A new signalling system in plants, related to that of strigolactone hormones but evolutionarily more ancient and functionally distinct, has been discovered. It is defined by the Karrkin-Insensitive-2 (KAI2) protein discovered by its ability to confer responsiveness to karrikins from bushfires. The KAI2 system influences seed germination, and development of seedlings, leaves and potentially roots. This project will use KAI2 mutants and transgenic plants to define the biological functions of KAI2 signalling, and its interactions with other signalling systems. New genes central to KAI2 signalling and responses will be identified for functional analysis. The research will reveal the significance of this new signalling system in plant biology.

How do sunflowers make protein drugs in their seeds? We recently discovered in sunflower the origin of a small protein ring that chemists have used for a decade to base designed drugs upon. This project aims to know how sunflowers make it so we may manipulate other plants to manufacture ring-based drugs.
Genetic evolution of plant proteins with biomedical applications. This project will draw upon a unique combination of skills in plant genetics and biomedical research to demonstrate that plants are not just a source of novel drugs. The results will show that they also provide a powerful biotechnological platform for the discovery, understanding, design and production of new pharmaceuticals.
A new and rapidly evolving class of plant peptides. The project will study a diverse class of drug-like mini-proteins that are thought to have emerged genetically over 12 million years ago. This project will explore why plants have kept making these mini-proteins for so long and whether it is the same reason the founding member of this mini-protein class is such a good drug.
