Oxygen Signalling in Grapevine Bud Dormancy. Dormancy is an important economic and ecological trait of many trees and crop plants, including most commercially valuable fruit species. This project aims to: define oxygen and radicals of oxygen as central cues of grapevine bud development and dormancy; identify and model the developmental processes that occur during dormancy onset, maintenance and release (bud burst); as well as to identify the molecular and biochemical regulators of oxygen signals ....Oxygen Signalling in Grapevine Bud Dormancy. Dormancy is an important economic and ecological trait of many trees and crop plants, including most commercially valuable fruit species. This project aims to: define oxygen and radicals of oxygen as central cues of grapevine bud development and dormancy; identify and model the developmental processes that occur during dormancy onset, maintenance and release (bud burst); as well as to identify the molecular and biochemical regulators of oxygen signals in bud dormancy. The knowledge generated could provide a platform to test impacts of climate change on fruit and tree species, and lead to better management of fruit and tree species in agricultural and ecological systems.Read moreRead less
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
Genomic basis of clonal variation in Cabernet Sauvignon wine grapes. The commercial practice of vegetative propagation results in novel clones through discrete mutations, creating challenges for horticultural and wine industries. This project will use cutting edge molecular profiling to design methods to map the identity of grapevines in whole vineyards, enabling industry to capture this variation for crop improvement.
Environment, Management and Compositional Quality of Fruit and Wine of the Grapevine, 'Chardonnay". This project seeks to maintain Australia`s competitive edge in the ultra premium and icon global wine market by seeking to identify new objective descriptors for Chardonnay. These can then be applied across the full spectrum of sites, climates and management for this variety. It comprises three sub-programs that are integrated with vineyard and winery management: 1, natural product chemistry of fr ....Environment, Management and Compositional Quality of Fruit and Wine of the Grapevine, 'Chardonnay". This project seeks to maintain Australia`s competitive edge in the ultra premium and icon global wine market by seeking to identify new objective descriptors for Chardonnay. These can then be applied across the full spectrum of sites, climates and management for this variety. It comprises three sub-programs that are integrated with vineyard and winery management: 1, natural product chemistry of fruit, 2, fine-scale, vine biology in relation to site, season and management, and 3, complex systems analyses applying modern database, multivariate and data-mining technologies to assess and communicate visually, the key drivers of compositional quality.Read moreRead less

An expanded ?health-claims? system will likely be enacted by Food Standards Australia New Zealand within two years. Horticultural industries are attracted to the promotional ?point of difference? this offers. Many health-promoting compounds are antioxidants, including polyphenols that are abundant in fruit such as grape and citrus. Antioxidants are also involved in the plant's defences against abiotic and biotic stress. Here, the WA Table Grape industry has committed funds for an APAI to study regulation of antioxidants in relation to nutritional and postharvest qualities. Effects of preconditioning with mild oxidative stresses will be assayed, postharvest, using molecular and biochemical techniques.Read moreRead less
Influence of high temperature on phenology, metabolism and the fate of axillary buds and inflorescences in grapevine. Subtropical regions in Australia, due to a warm climate, land and water availability, have the potential to produce a variety of agricultural produce, particularly fruit, to meet market demand.

Subtropical regions in Australia, due to a warm climate, land and water availability, have the potential to produce a variety of agricultural produce, particularly fruit, to meet market demand. However adoption of fruit crops, many of which, including table grape, have temperate origins, requires intensive management. Despite years of agronomic R&D, production remains variable due to a lack of fundamental knowledge on how climate impacts on the development cycle, particularly flowering, required to produce fruit. This proposal will carry out basic research to provide knowledge that will enable consistent production and expansion of table grape and other temperate crop industries.Read moreRead less
Dissecting chloride transport in plants to secure an untapped source for improving plant productivity. Chloride and nitrate are central to physiological processes that determine crop yield and food production, but their uptake and transport within the plant body are antagonistic.

Chloride and nitrate are central to physiological processes that determine crop yield and food production, but their uptake and transport within the plant body are antagonistic. This project will gain a fundamental understanding of the mechanisms underlying this antagonism. This will provide new tools for improving salinity tolerance and the efficiency of fertiliser use, which can be used for the development of new crop varieties. Improving these traits will be essential if we are to successfully address the threats to Australian and global food security posed by salinity, and the rising economic and environmental costs of inefficient fertiliser use.Read moreRead less
