Developing molecular and physiological markers for marker-assisted barley breeding for waterlogging tolerance. The overall loss in crop production due to waterlogging is second largest after drought, and more than 5 million hectares in Australia are prone to waterlogging. This project will develop physiological and molecular markers allowing for the development of waterlogging tolerant crops, thus contributing to the National Goal of ‘Responding to Climate Change and Variability’.
Membrane transporters in oxidative stress signalling and tolerance in plants. Oxidative stress imposed by salinity and drought severely limits agricultural crop production, resulting in multibillion dollar losses to farmers. Australia is one of the driest continents, with a significant proportion of arable land affected by salinity. Thus, developing salt- and drought tolerant species is critical to minimise the impact of these stresses on crop production. This project will reveal specific ionic ....Membrane transporters in oxidative stress signalling and tolerance in plants. Oxidative stress imposed by salinity and drought severely limits agricultural crop production, resulting in multibillion dollar losses to farmers. Australia is one of the driest continents, with a significant proportion of arable land affected by salinity. Thus, developing salt- and drought tolerant species is critical to minimise the impact of these stresses on crop production. This project will reveal specific ionic mechanisms mediating reactive oxygen species signalling and tolerance in plants. This will help achieve the above goal by providing plant breeders with vital information on key genes controlling oxidative stress tolerance in plants. Read moreRead less
Coping with flooding: nutrient transport in oxygen-deprived roots. Flooding damages plants by reducing oxygen supply to roots. The project will study effects of low oxygen on nutrient transport by roots. Understanding root functioning during low oxygen will enhance knowledge of plant acclimation to soil water logging. The project will contribute to the National Goal of 'Responding to Climate Change and Variability'.
Halophytes for high-saline agriculture: optimising performance and understanding physiology. The recent drought has shaved off up to 1 per cent of Australia's economic growth and resulted in losses of over $6 billion in crop and livestock production. At the same time, very large volumes of water with impaired chemical quality are generated by industry and municipal water treatment processes. In most cases, these cannot be used directly for crop irrigation and have to be disposed of at extreme co ....Halophytes for high-saline agriculture: optimising performance and understanding physiology. The recent drought has shaved off up to 1 per cent of Australia's economic growth and resulted in losses of over $6 billion in crop and livestock production. At the same time, very large volumes of water with impaired chemical quality are generated by industry and municipal water treatment processes. In most cases, these cannot be used directly for crop irrigation and have to be disposed of at extreme cost and waste. This project will utilise halophytes as 'alternative cash crops' to use the saline water produced by the coal seam gas operations in the Surat Basin area in Queensland. This will result in a saving of at least $48 million over the five years of operation.Read moreRead less
Genetic control of flowering in legumes. Flowering in plants is strongly regulated by environmental factors, with important consequences for their natural distribution and use in agriculture. This project will isolate genes, characterize genetic diversity and dissect molecular mechanisms that regulate flowering, contributing to fundamental biology, crop improvement and research training.
The failure-threshold of leaves in drought. This project aims to reveal how specific water-stress thresholds damage the leaves of Australian crop and forest species during drought. Water stress affects agricultural productivity and plant survival in drought-prone regions such as Australia. Using optical and X-ray techniques, this project seeks to visualise and quantify the dynamic processes of damage and repair in leaves under stress. Anticipated outputs include a practical basis to predict drou ....The failure-threshold of leaves in drought. This project aims to reveal how specific water-stress thresholds damage the leaves of Australian crop and forest species during drought. Water stress affects agricultural productivity and plant survival in drought-prone regions such as Australia. Using optical and X-ray techniques, this project seeks to visualise and quantify the dynamic processes of damage and repair in leaves under stress. Anticipated outputs include a practical basis to predict drought-induced canopy death; identification of threats to ecologically sensitive plants; and selection and screening tools to improve the drought resilience of agriculturally important crop species.Read moreRead less
Ion transporters regulating plant adaptive responses to salinity and the modes of their control by compatible solutes in plant cells. Plants respond to saline conditions by a significant elevation in the level of compatible solutes in the cytosol. It appears that these solutes are not directly involved in conventional osmoprotection, but instead have a regulatory role in cell metabolism. This project will apply a range of state-of-the-art biophysical and molecular techniques to investigate the m ....Ion transporters regulating plant adaptive responses to salinity and the modes of their control by compatible solutes in plant cells. Plants respond to saline conditions by a significant elevation in the level of compatible solutes in the cytosol. It appears that these solutes are not directly involved in conventional osmoprotection, but instead have a regulatory role in cell metabolism. This project will apply a range of state-of-the-art biophysical and molecular techniques to investigate the modes of control exercised by compatible solutes over the activity of major plasma membrane transporters involved in plant adaptive responses to salinity. The work will substantially advance our understanding of salt tolerance and will provide a sound basis for genetic engineering of salt tolerant crops.Read moreRead less
Reducing environmental footprint by improving phosphorous use efficiency. While modern agriculture relies heavily on the use of phosphorous fertilizers, most of them are not used by plants and lost in runoff, resulting in a massive environmental damage through contamination of waterways (termed eutrophication). This project takes advantage of an untapped resource - a unique collection of Tibetan wild barley genotypes, to reveal key traits that confer superior phosphorus use efficiency in wild ba ....Reducing environmental footprint by improving phosphorous use efficiency. While modern agriculture relies heavily on the use of phosphorous fertilizers, most of them are not used by plants and lost in runoff, resulting in a massive environmental damage through contamination of waterways (termed eutrophication). This project takes advantage of an untapped resource - a unique collection of Tibetan wild barley genotypes, to reveal key traits that confer superior phosphorus use efficiency in wild barley and identify appropriate candidate genes and their position on chromosomes for further incorporating these traits into commercial barley cultivars. This will reduce the environmental footprint of modern agricultural practices on terrestrial and aquatic ecosystems without compromising food security.Read moreRead less
