A novel reversible male sterility system for hybrid seed production in canola, cotton and oilseed mustard. Demand for grains, fibre and other agricultural products has recently increased significantly. Hence, the security of food production is emerging as a critical global issue. We have identified a central component (AtMYB103) controlling tapetum and thus pollen development and designed a novel reversible male sterility system using AtMYB103. The efficient hybrid seed production systems develo ....A novel reversible male sterility system for hybrid seed production in canola, cotton and oilseed mustard. Demand for grains, fibre and other agricultural products has recently increased significantly. Hence, the security of food production is emerging as a critical global issue. We have identified a central component (AtMYB103) controlling tapetum and thus pollen development and designed a novel reversible male sterility system using AtMYB103. The efficient hybrid seed production systems developed in this project for canola, cotton and mustard will increase the productivity of the Australian oilseed and fibre industries. AtMYB103 gene is conserved among many crop plants. Hence, the new technologies and knowledge gained will be applicable to a wide range of crop plants and have important implications for the agricultural and food industries.Read moreRead less
Gene identification and genetic marker analysis of herbicide resistance in Lolium rigidum. Herbicide resistance threatens the vibrant, export-focused Australian cropping industry and environmental sustainability. The Australian herbicide resistance problem is far greater than elsewhere in the world. Herbicide resistance must be avoided, managed and reversed to ensure profitable agriculture and an environmentally sustainable landscape. This research will contribute to the national wealth through ....Gene identification and genetic marker analysis of herbicide resistance in Lolium rigidum. Herbicide resistance threatens the vibrant, export-focused Australian cropping industry and environmental sustainability. The Australian herbicide resistance problem is far greater than elsewhere in the world. Herbicide resistance must be avoided, managed and reversed to ensure profitable agriculture and an environmentally sustainable landscape. This research will contribute to the national wealth through helping ensure the profitability of vital Australian export agricultural industries and the sustainability of the soil/land resource. This proposal will ensure that Australia leads international herbicide resistance research and will enable the capture of intellectual property and commercial opportunities. Read moreRead less
Assembly and function of arabinogalactan-proteins: a class of proteoglycans involved in plant growth and development. We aim to define the mechanisms by which a family of cell surface proteoglycans, the arabinogalactan-proteins (AGPs), are assembled and contribute to the regulation of plant growth and development using Arabidopsis, a model system amenable to a functional genomics strategy. This will be achieved through the application of bioinformatics for gene discovery and molecular, biochemi ....Assembly and function of arabinogalactan-proteins: a class of proteoglycans involved in plant growth and development. We aim to define the mechanisms by which a family of cell surface proteoglycans, the arabinogalactan-proteins (AGPs), are assembled and contribute to the regulation of plant growth and development using Arabidopsis, a model system amenable to a functional genomics strategy. This will be achieved through the application of bioinformatics for gene discovery and molecular, biochemical and genetics approaches to define gene function. Understanding mechanisms that control plant growth and development will ultimately impact on industries (agriculture, horticulture and forestry) vital to Australia's prosperity.Read moreRead less

Achievements of the Objectives will specifically address National Research Priority 3 by developing breakthrough science and utilising frontier technologies with application to Australia's agri-biotechnology industries. In addition to contributing to world class research outcomes, we will train highly skilled graduates and postdoctoral fellows in functional genomics technologies, thereby contributing to the "knowledge nation".Read moreRead less
Characterisation and selection of phytocompound and physical seed quality characters of chickpea (Cicer arietinum). To develop and expand both value and volume of the Australian market share for chickpea. Retention and expansion of existing markets will occur through improved seed physical traits such as size, colour and processing efficiency, whilst creation of new markets will be achieved through enhancing novel traits such as the level of phytocompounds. In collaboration with Victoria's Dep ....Characterisation and selection of phytocompound and physical seed quality characters of chickpea (Cicer arietinum). To develop and expand both value and volume of the Australian market share for chickpea. Retention and expansion of existing markets will occur through improved seed physical traits such as size, colour and processing efficiency, whilst creation of new markets will be achieved through enhancing novel traits such as the level of phytocompounds. In collaboration with Victoria's Department of Primary Industry staff, genes governing chickpea quality traits will be characterised through applying novel combinations of selection and analytical methods. A multidsciplinary team of plant breeders, grains chemists and molecular biologists will advance chickpea breeding in Australia by applying cutting-edge technologies.Read moreRead less
Seed quality and disease resistance trait mapping in lentil (Lens culinaris ssp. culinaris). To protect and increase our world lentil market share, the mission of the Australian lentil breeders is to develop lentil varieties with superior seed qualities. Three highly desirable seed quality traits are; fatter and larger shape, better splitting efficiency and resistance to blemishing by ascochyta blight infection. To speed up the development of varieties with these traits, the genetic loci governi ....Seed quality and disease resistance trait mapping in lentil (Lens culinaris ssp. culinaris). To protect and increase our world lentil market share, the mission of the Australian lentil breeders is to develop lentil varieties with superior seed qualities. Three highly desirable seed quality traits are; fatter and larger shape, better splitting efficiency and resistance to blemishing by ascochyta blight infection. To speed up the development of varieties with these traits, the genetic loci governing them will be characterised and closely associated molecular markers identified. Markers will be validated for their use in marker-assisted breeding programs via back-crossing and field and glass house testing.Read moreRead less
Pyramiding ascochyta blight (A. rabiei) resistance in chickpea. Ascochyta blight (A. rabiei) is the most devastating disease that affects chickpea production in Australia. This project will produce enhanced chickpea breeding germplasm with sustainable resistance to ascochyta blight. This will be achieved through the enrichment of highly informative genome linkage maps and the development of molecular markers closely associated with novel resistance genes. Markers will be used to screen backcross ....Pyramiding ascochyta blight (A. rabiei) resistance in chickpea. Ascochyta blight (A. rabiei) is the most devastating disease that affects chickpea production in Australia. This project will produce enhanced chickpea breeding germplasm with sustainable resistance to ascochyta blight. This will be achieved through the enrichment of highly informative genome linkage maps and the development of molecular markers closely associated with novel resistance genes. Markers will be used to screen backcrossed populations for novel resistance in order to pyramid the genes involved. The most resistant lines, to all of the A. rabiei pathotypes, will be selected for use in future resistance breeding programs.Read moreRead less
