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
Novel cell wall genes ripe for the picking. This project aims to investigate the role of recently discovered plant cellulose synthase-like CslM genes and to define the polysaccharide product associated with them. Successful identification of the polysaccharide is highly likely to increase our fundamental understanding of how cell walls are made, how cells stick together or fall apart as well as facilitating the training of the next generation of cell wall biologists in challenging molecular and ....Novel cell wall genes ripe for the picking. This project aims to investigate the role of recently discovered plant cellulose synthase-like CslM genes and to define the polysaccharide product associated with them. Successful identification of the polysaccharide is highly likely to increase our fundamental understanding of how cell walls are made, how cells stick together or fall apart as well as facilitating the training of the next generation of cell wall biologists in challenging molecular and biochemical techniques. This new knowledge could increase our understanding of fruit ripening, and how it might be manipulated. This could have significant downstream commercial benefits if applied to breeding programs of economically important fruit such as grapes, tomatoes and strawberries.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.

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
Clay nanoparticle-facilitated RNAi for non-transgenic modification of crops. This project aims to define the most effective spray formulations, consisting of clay nanoparticles and induced RNA interference (RNAi) to manipulate gene expression in plants. Topical application of double-stranded RNA (dsRNA) for RNAi represents an attractive alternative to genetically engineered crops. However, naked dsRNA is unstable and is not efficiently taken up by plants. For these reasons, topical application o ....Clay nanoparticle-facilitated RNAi for non-transgenic modification of crops. This project aims to define the most effective spray formulations, consisting of clay nanoparticles and induced RNA interference (RNAi) to manipulate gene expression in plants. Topical application of double-stranded RNA (dsRNA) for RNAi represents an attractive alternative to genetically engineered crops. However, naked dsRNA is unstable and is not efficiently taken up by plants. For these reasons, topical application of dsRNA has thus far produced only modest induction of RNAi in plants. Nanoparticle-facilitated manipulation of gene expression in plants will enable sustainable clean green strategies for protecting crops from diseases. This project will result in improved crop protection and productivity and boost the export potential of Australian crops.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. 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 ca ....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. 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.
