Control of developmental switches by importin 5. Aims: This project will study a key molecular switch called IPO5, a protein that is required for cells and organs to form and function normally, and it will reveal how it works.
Significance: These experiments will provide the first complete description of how this molecular switch controls the behaviour of a cell across its lifespan. IPO5 is highly conserved, so these studies will be relevant to a wide range of animals.

Significance: These experiments will provide the first complete description of how this molecular switch controls the behaviour of a cell across its lifespan. IPO5 is highly conserved, so these studies will be relevant to a wide range of animals.
Expected Outcomes: This knowledge will reveal how IPO5 controls formation of sperm by revealing what other proteins it binds to and how this affects cell signaling and responses to the environment.
Benefits: This will provide information about potential interventions to control fertility or to repair abnormal cells.

Spermatogonial stem cells in the testis are an untapped resource for species conservation. This project aims to characterise metabolic pathways that control spermatogonial stem cell function, and define the conserved nature of these pathways between model species (mouse) and vulnerable Australian native fauna. Expected outcomes of this project include an enhanced capacity to culture koala spermatogonia in vitro, which will be a first step towards using spermatogonial biobanking as a tool to maintain genetic diversity in this species. Outcomes from this study should provide significant benefits in safeguarding our unique Australian native species, which is of particular importance following the catastrophic 2019/20 bushfire season.Read moreRead less

Cellular stress is responsible for widespread inefficiencies in plant and animal reproduction. Using high resolution proteomics and cryo-electron microscopy, this project aims to investigate how plant and animal germ cells respond to environmental stresses that are known to disrupt fertility, and assess two novel strategies to decrease the sensitivity of cells to stress. This project is expected to generate new global knowledge in the area of fertility regulation with the potential to improve the tolerance of crop species to heat stress, prevent economic losses and help to secure future food production. Further, this project has the intended benefit of improving the fertility of animal species that suffer from stress-induced infertility.

Protecting cereal grain development at high temperatures. This project aims to investigate new temperature-responsive factors that regulate cereal grain development to protect grain production under heat stress. The new research will leverage international collaborations with access to cutting-edge genetic and technological resources, and refine novel X-ray imaging techniques in Australia, to observe how temperature affects flower structure and function in barley and rice.

This project aims to investigate new temperature-responsive factors that regulate cereal grain development to protect grain production under heat stress. The new research will leverage international collaborations with access to cutting-edge genetic and technological resources, and refine novel X-ray imaging techniques in Australia, to observe how temperature affects flower structure and function in barley and rice. Favourable mutations that optimise plant yield and fitness will be defined and explored in other, more complex, cereals such as wheat. Expected outcomes will be fundamental breakthroughs in understanding how plants respond to, and buffer, the effects of heat to lead to translational breeding strategies that bolster grain yield.Read moreRead less
Inflammation as an early form of maternal-fetal signalling in pregnancy. The project aims to understand the role of inflammatory signalling in marsupial pregnancy. This project is expected to explain why inflammation, a processes normally confined to injury and infection, is a part of reproduction in live-bearing mammals. Outcomes of this project include robust measures of the capacity for, impact of, and evolution of, inflammatory signalling in marsupial pregnancy.

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.

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

Building resilient alpine environments with less snow. In this project, we aim to build resilience into alpine National Parks and Alpine Resorts to counter the effects of ongoing declines in snow. Alpine environments depend on snow to regulate water flows, insulate vegetation, control soil erosion and promote proper ecosystem functioning.

Alpine environments depend on snow to regulate water flows, insulate vegetation, control soil erosion and promote proper ecosystem functioning. How these processes will operate in a snow-free future is unknown. We will determine how and where snow characteristics drive soil water availability for plants and which plant species have the best adaptation and regeneration potential under extreme conditions such as heat, frost and drought. Benefits of the project include innovative land management and rehabilitation solutions, to safeguard Australia's alpine areas under changing environmental conditions.Read moreRead less
