Long noncoding RNAs and their regulatory roles in epigenetic control of gene expression in plants. Epigenetic control of gene expression plays a critical role in development, environmental adaptation, stress response and disease resistance in plants, but its molecular basis remains largely unknown. The proposed study should contribute to the emerging field of epigenetics by discovering new regulatory noncoding RNAs involved in epigenetic mechanisms in plants. These new discoveries could potentia ....Long noncoding RNAs and their regulatory roles in epigenetic control of gene expression in plants. Epigenetic control of gene expression plays a critical role in development, environmental adaptation, stress response and disease resistance in plants, but its molecular basis remains largely unknown. The proposed study should contribute to the emerging field of epigenetics by discovering new regulatory noncoding RNAs involved in epigenetic mechanisms in plants. These new discoveries could potentially provide new opportunities and platforms for improving the performance, yield and quality of crop plants. The proposed study is therefore consistent with the national research priority goals such as breakthrough science, frontier technologies and promoting an innovation culture.Read moreRead less
Characterisation of PQ loop proteins in plants: are they voltage insensitive nonselective cation channels? Millions of hectares of Australian agricultural land are affected by salinity. This results in the loss of hundreds of millions of dollars in revenue each year. The identification of the pathway for the initial influx of Na+ into plants from the soil will be important in helping to develop crop plants that are salt tolerant. This will increase our understanding of the mechanisms of salinity ....Characterisation of PQ loop proteins in plants: are they voltage insensitive nonselective cation channels? Millions of hectares of Australian agricultural land are affected by salinity. This results in the loss of hundreds of millions of dollars in revenue each year. The identification of the pathway for the initial influx of Na+ into plants from the soil will be important in helping to develop crop plants that are salt tolerant. This will increase our understanding of the mechanisms of salinity tolerance, an area of great importance to Australian agriculture and environmental sustainability. The future applications of this work will increase agricultural productivity and enhance the quality of life for both Australians and the international community.Read moreRead less

Summary
Isotope Ratio Mass Spectrometry Facility for Nitrogen and Water Analysis in Plants. Continual improvement to agricultural plant production is key to maintaining future sustainable growth in Australian agriculture. Our respective research teams are focussed on improving how plants utilise both nitrogen and water. Many questions remain with respect to where, how and when plants use and or access these important nutrients. The proposed facility will enable plant scientists to begin in-depth anal ....Isotope Ratio Mass Spectrometry Facility for Nitrogen and Water Analysis in Plants. Continual improvement to agricultural plant production is key to maintaining future sustainable growth in Australian agriculture. Our respective research teams are focussed on improving how plants utilise both nitrogen and water. Many questions remain with respect to where, how and when plants use and or access these important nutrients. The proposed facility will enable plant scientists to begin in-depth analysis of both nitrogen transport mechanisms and the ability to model root development and water allocation in crop species. This research will ultimately lead to improved knowledge on how plants respond to their environment and where modifications can be made to generate sustainable crops suited to Australian agriculture.Read moreRead less

Joint Facility for Genome Analysis of Nutrient Transport Proteins. The joint facility for genome analysis of nutrient transport proteins is a new initiative between the University of Adelaide, the Australian Centre for Plant Functional Genomics, and the University of Western Australia to use a high throughput Xenopus oocyte expression system to screen plant cDNA/cRNA collections for genes encoding nutrient transport proteins. The facility will also provide a platform to rapidly accelerate our p ....Joint Facility for Genome Analysis of Nutrient Transport Proteins. The joint facility for genome analysis of nutrient transport proteins is a new initiative between the University of Adelaide, the Australian Centre for Plant Functional Genomics, and the University of Western Australia to use a high throughput Xenopus oocyte expression system to screen plant cDNA/cRNA collections for genes encoding nutrient transport proteins. The facility will also provide a platform to rapidly accelerate our present capacity for Xenopus oocyte expression analysis of nutrient transport proteins. This facility will greatly aid our current research quantum in this field and allow for new discoveries related to nutrient transport in plants.Read moreRead less
A novel role for phytochrome in dormancy release inhibition. Seed dormancy contributes to the persistence of weeds in agriculture by enabling seeds to remain viable in the soil for many years, and is a major reason why annual ryegrass (Lolium rigidum) has become the most economically damaging weed in Australian agriculture. Recently we discovered a new way to control dormancy release and germination in these seeds. This project to identify the changes occurring within the seeds during dormancy r ....A novel role for phytochrome in dormancy release inhibition. Seed dormancy contributes to the persistence of weeds in agriculture by enabling seeds to remain viable in the soil for many years, and is a major reason why annual ryegrass (Lolium rigidum) has become the most economically damaging weed in Australian agriculture. Recently we discovered a new way to control dormancy release and germination in these seeds. This project to identify the changes occurring within the seeds during dormancy release will underpin our efforts to manipulate emergence timing in order to improve the efficacy of current weed control practices and contribute to sustainable farming systems.Read moreRead less
Does plasma membrane perception of 2,4-D influence auxin resistance? This project aims to investigate the role of the cell membrane in synthetic auxin herbicide resistance by analysing the functions and interaction partners of candidate resistance proteins. It is expected that this project will generate new knowledge about the very early response of plants to auxin and the difference between susceptible and resistant weeds in perceiving auxin herbicides. Expected outcomes of this project include ....Does plasma membrane perception of 2,4-D influence auxin resistance? This project aims to investigate the role of the cell membrane in synthetic auxin herbicide resistance by analysing the functions and interaction partners of candidate resistance proteins. It is expected that this project will generate new knowledge about the very early response of plants to auxin and the difference between susceptible and resistant weeds in perceiving auxin herbicides. Expected outcomes of this project include the identification of potential herbicide synergists and a greater understanding of how weeds develop resistance to auxin herbicides. This should benefit Australian grain growers by providing more effective weed control options and lessening the amount of unnecessarily-applied herbicide in the environment.Read moreRead less
