Ascorbate and glutathione integrate the control of grapevine development. This project aims to make a step-change in understanding how the growth of woody perennial crops is regulated. The study of herbaceous annual plants has established that the antioxidants, ascorbate and glutathione, are important in regulating every step of plant development. However, this cannot readily translate to perennial life cycles. This project will develop novel genetic tools in grapevine that enable functional stu ....Ascorbate and glutathione integrate the control of grapevine development. This project aims to make a step-change in understanding how the growth of woody perennial crops is regulated. The study of herbaceous annual plants has established that the antioxidants, ascorbate and glutathione, are important in regulating every step of plant development. However, this cannot readily translate to perennial life cycles. This project will develop novel genetic tools in grapevine that enable functional studies of these antioxidants in a perennial plant for the first time. It will investigate how ascorbate and glutathione regulate the development of grapevine, and how these functions integrate with hormone and energy metabolism. The outcomes will advance our ability to manage perennial crops in current and future climates.Read moreRead less
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
Solving smoke taint: Overcoming the impacts of vineyard exposure to smoke. Vineyard exposure to bushfire smoke can taint grapes, causing significant revenue losses where smoky, ashy characters render wine unsaleable. Smoke taint therefore remains an ongoing threat to the viability of the wine industry. This project aims to safeguard grape and wine quality by building the wine industry’s capacity to predict, mitigate and respond to risk associated with vineyard smoke exposure. Expected outcomes i ....Solving smoke taint: Overcoming the impacts of vineyard exposure to smoke. Vineyard exposure to bushfire smoke can taint grapes, causing significant revenue losses where smoky, ashy characters render wine unsaleable. Smoke taint therefore remains an ongoing threat to the viability of the wine industry. This project aims to safeguard grape and wine quality by building the wine industry’s capacity to predict, mitigate and respond to risk associated with vineyard smoke exposure. Expected outcomes include establishing the mechanism by which smoke compounds are taken up by grapes and the factors that influence their sensory impact on wine. The development of innovative and interdisciplinary strategies for detecting and alleviating smoke taint will deliver important economic benefit to the Australian wine sector.Read moreRead less
Finding the missing links in salt and water transport in plants. Grain crops and horticultural plants use proteins called aquaporins to move water across cell membranes, but a group of these proteins can also transport some important nutrient ions as well as toxic sodium ions. This project aims to reveal the molecular pathways that regulate water and ion transport via aquaporins using advanced techniques in biophysics and molecular biology. These results will provide novel insights into how plan ....Finding the missing links in salt and water transport in plants. Grain crops and horticultural plants use proteins called aquaporins to move water across cell membranes, but a group of these proteins can also transport some important nutrient ions as well as toxic sodium ions. This project aims to reveal the molecular pathways that regulate water and ion transport via aquaporins using advanced techniques in biophysics and molecular biology. These results will provide novel insights into how plants coordinate and adapt to changing water and salt conditions, addressing a missing link in how ions and water move in and out of plant vacuoles. Benefits include an expanded, innovative range of targets for plant breeding programs to improve plant productivity in our changing climate.Read moreRead less
Root-to-shoot: modeling the salt stress response of a plant vascular system. Salt and drought are the two major abiotic stresses affecting crop plant health, growth and development. We aim to understand salt and water transport in plants and the physiological effects of soil salinity. Using biophysical models, we will quantify the movement of salt through plant organs, tissues and cells, from root to leaf. We aim to answer the question of how salt moves across the different tissues and major org ....Root-to-shoot: modeling the salt stress response of a plant vascular system. Salt and drought are the two major abiotic stresses affecting crop plant health, growth and development. We aim to understand salt and water transport in plants and the physiological effects of soil salinity. Using biophysical models, we will quantify the movement of salt through plant organs, tissues and cells, from root to leaf. We aim to answer the question of how salt moves across the different tissues and major organs, how salt accumulates in root, leaf and shoot cells, and how movement and accumulation is controlled by the diversity of transport mechanisms operating in plants. We aim to quantify tissue tolerance, osmotic tolerance and ionic tolerance and discover new mechanisms by which plants can stave off the effect of salt stress.Read moreRead less

The ARC Training Centre for Innovative Wine Production aims to tackle challenges to wine production through innovative, multi-disciplinary research. Australia’s grape and wine industry is a multi-billion dollar industry, yet in some areas profitability is low. Reasons include extreme weather events, soil salinity and diseases, inefficient practices, a low level of technological innovation and high input costs. New technologies and process efficiencies developed as part of this project will reduce environmental impact, drive production costs down and profits and employment up. The project will mount a suite of industry-led projects to deliver outcomes to boost Australia’s competitiveness as a supplier of sustainably-produced premium branded wine to the world.Read moreRead less
