Fertility crisis: harnessing the genomic tension behind pollen fertility in sorghum. Hybrid sorghum varieties yield more grain than inbred varieties but the production seed for farmers can be difficult. This project will identify the genes responsible for a trait that makes hybrid seed production possible and this knowledge will help raise sorghum yields in Australian and in some of the world’s poorest countries.
An integrated molecular approach to human gene regulation. This proposal aims to reveal how the interaction of nuclear RNA and protein molecules control gene regulation in the face of cell stress. To understand how genetic variation leads to changes in the expression of genes, we need new insights into the fundamental principles underpinning complex gene regulatory systems. Building on the discovery of paraspeckles, novel gene regulatory structures, this project will yield insights into gene reg ....An integrated molecular approach to human gene regulation. This proposal aims to reveal how the interaction of nuclear RNA and protein molecules control gene regulation in the face of cell stress. To understand how genetic variation leads to changes in the expression of genes, we need new insights into the fundamental principles underpinning complex gene regulatory systems. Building on the discovery of paraspeckles, novel gene regulatory structures, this project will yield insights into gene regulation that will help fill these knowledge gaps. This will provide a more comprehensive understanding of RNA-mediated gene regulation, and will open up new research opportunities to target RNA based gene regulatory complexes.Read moreRead less

Summary
Role of DNA methylation in response to low nutrient availability in plants. DNA methylation (mC) is a covalent modification of DNA essential for the establishment and maintenance of correct gene expression patterns and recently suggested to be responsive to some environmental cues in plants. Using cutting edge technologies, this project aims to identify nutrient stress-induced mC changes and investigate the role that these changes may play in transcriptional regulation, as well as assessing whet ....Role of DNA methylation in response to low nutrient availability in plants. DNA methylation (mC) is a covalent modification of DNA essential for the establishment and maintenance of correct gene expression patterns and recently suggested to be responsive to some environmental cues in plants. Using cutting edge technologies, this project aims to identify nutrient stress-induced mC changes and investigate the role that these changes may play in transcriptional regulation, as well as assessing whether these changes can be transmitted to the next generation to confer intergenerational stress responsiveness. Altogether this project aims to provide fundamental knowledge of the role of mC in plant gene regulation and stress response as well as paving the way for the next generation of novel crop-improvement strategies.Read moreRead less

This project aims to give Western Australian researchers direct access to new platforms in single-cell isolation and single-cell RNA, genome and exome sample library preparation, so they can participate in the precision single-cell based research driving biology worldwide. This project will give researchers access to single-cell analysis techniques, integrated with other analysis methods, microscopy, and preclinical imaging. The characterisation of rare and complex biological samples is expected to advance effective, socio-economically important research programmes in cell and molecular biology, sports science, plant and crop sciences, agriculture, clean energy (biofuels) resources and production, greenhouse gas reduction, environmental microbiology and marine science.Read moreRead less
Unique epigenetic states in plant stem cell niches for safeguarding genome integrity. Plant stem cells are the foundation cells of all plant growth and development, including generation of the reproductive cells. Therefore, it is critical that stem cells defend against attacks that may damage the genome. A unique epigenetic state in plant stem cell niches has been discovered that may protect the genome from damage due to parasitic DNA elements. Using sophisticated genomics, genetics, and cellula ....Unique epigenetic states in plant stem cell niches for safeguarding genome integrity. Plant stem cells are the foundation cells of all plant growth and development, including generation of the reproductive cells. Therefore, it is critical that stem cells defend against attacks that may damage the genome. A unique epigenetic state in plant stem cell niches has been discovered that may protect the genome from damage due to parasitic DNA elements. Using sophisticated genomics, genetics, and cellular technologies, this project will investigate how stem cell epigenetic state is linked to genome defence, how environmental stresses can disrupt the defence system, and the role of the system in driving new genetic diversity. This knowledge is of high importance as agricultural crops enter an era of increasingly challenging conditions.Read moreRead less
The evolution and conservation consequences of promiscuity in plants pollinated by vertebrates. Pollen dispersal between plants, predominantly by insects and wind, is characteristically restricted to nearest neighbours. Recent molecular analysis of paternity for a Banksia pollinated by nectar-feeding birds showed atypical pollen dispersal, with high multiple paternity, wide outcrossing and local panmixis. With much of the Australian flora also bird-pollinated, our initial results have potentiall ....The evolution and conservation consequences of promiscuity in plants pollinated by vertebrates. Pollen dispersal between plants, predominantly by insects and wind, is characteristically restricted to nearest neighbours. Recent molecular analysis of paternity for a Banksia pollinated by nectar-feeding birds showed atypical pollen dispersal, with high multiple paternity, wide outcrossing and local panmixis. With much of the Australian flora also bird-pollinated, our initial results have potentially wide and novel significance. This project proposes to test the generality of our observations for other vertebrate-pollinated species, and to test the conservation and evolutionary consequences of reduced pollen dispersal caused by habitat fragmentation and declining pollinators for a pollination paradigm facilitating promiscuity.Read moreRead less
The roles and regulators of new plant cells linked to root transport. Plant genomics has moved to the single cell resolution, allowing precise investigations of previously hidden cell types and cell states that respond to environmental stress and that vary among differentially adapted plant populations.

Plant genomics has moved to the single cell resolution, allowing precise investigations of previously hidden cell types and cell states that respond to environmental stress and that vary among differentially adapted plant populations. Here, we will extend our pioneering efforts that have mapped and discovered novel root cell types, to determine their salt and nutrient stress responses, and to elegantly dissect the underling causal genetic variation. The unique cell markers and regulatory networks will be validated with tissue specific and transgenic tools that can work across a host of plant species to reveal adaptive cellular responses to harsh environmental conditions.Read moreRead less
Deciphering the regulation and function of the epigenome in eukaryotic development and stress response. The epigenome is an additional regulatory code superimposed upon plant and animal genomes that controls how they operate. This project will aim to understand the information encoded in the epigenome and how it changes in development and environmental stress, enabling manipulation of its function in crops and correction of its dysfunction in disease.
