Lamarckian lizards: novel integration of telomere epigenetics, free radicals and innate antioxidants in condition-dependant sexual signal evolution. In 2009, the Nobel Prize in physiology was awarded Drs. Blackburn, Greider and Szostak for discoveries on telomeres. This project will investigate how telomeres not only cap chromosomes from destruction by free radicals, but also have a key role in life itself, in their influence on ageing, longevity, ornaments and lifetime reproductive success.
Breeding for improved Australian hop varieties by induced mutations. Hop (Humulus lupulus) plants are vital to the brewing industry. Their main commercial products are alpha-acids and oils, which contribute to the bitter taste and aroma of beer. Hops possess different alpha-acids, including humulone (desirable) and cohumulone (non-desirable), and different oils, including humulene (desirable). Recently, beta-acids have been identified as useful compounds for emerging markets. Induced mutagen ....Breeding for improved Australian hop varieties by induced mutations. Hop (Humulus lupulus) plants are vital to the brewing industry. Their main commercial products are alpha-acids and oils, which contribute to the bitter taste and aroma of beer. Hops possess different alpha-acids, including humulone (desirable) and cohumulone (non-desirable), and different oils, including humulene (desirable). Recently, beta-acids have been identified as useful compounds for emerging markets. Induced mutagenesis will be used to alter the genetic make-up of hops, to obtain varieties with: (i) higher humulone; (ii) lower cohumulone; (iii) higher humulene; and (iv) higher beta-acids. This research will greatly assist the Australian hop industry by short-cutting traditional breeding performed by crossing.Read moreRead less
Genetic control of flowering and photoperiodism in pea. The timing of flowering in many plant species is strongly influenced by photoperiod. The mechanisms by which photoperiod controls flowering will be investigated using the garden pea as a model system. New pea mutants impairing photoperiod responses will be identified and characterized, and photoperiod response genes from Arabidopsis will be mapped and used for expression studies in pea. This work will provide important new information about ....Genetic control of flowering and photoperiodism in pea. The timing of flowering in many plant species is strongly influenced by photoperiod.

New pea mutants impairing photoperiod responses will be identified and characterized, and photoperiod response genes from Arabidopsis will be mapped and used for expression studies in pea. This work will provide important new information about the physiological roles of the Arabidopsis genes and the molecular identity of the pea genes. It will add to our knowledge of how flowering is regulated, and this will have important agronomic applications.Read moreRead less
Comparative genetics of flowering and photoperiod responsiveness in legumes. The results from this project will add to our basic knowledge of the way in which environmental factors influence flowering in plants. The timing and duration of flowering is a critical determinant of yield for many crop species, and of market value for many ornamental species. A better understanding of the basic genetics and physiology of flowering will thus be relevant for plant breeders and horticulturalists seeking ....Comparative genetics of flowering and photoperiod responsiveness in legumes.

The timing and duration of flowering is a critical determinant of yield for many crop species, and of market value for many ornamental species. A better understanding of the basic genetics and physiology of flowering will thus be relevant for plant breeders and horticulturalists seeking to modify flowering responses to suit particular production strategies, and will help to maintain the strong position of Australia as a world leader in applied aspects of plant/environment interactions. It will also strengthen the international reputation of Australia for high-quality basic research in plant development.Read moreRead less

Genetic legacy of climate change in Australian temperate forests. This work will make a significant contribution to the understanding of the Quaternary history of the forests of south-eastern Australia. Finding the location of glacial refugia is crucial to the development of long-term conservation strategies, as they are areas of high genetic and species diversity. Understanding the evolutionary processes that affect genetic diversity and gene flow of these keystone species (Nothofagus cunningha ....Genetic legacy of climate change in Australian temperate forests. This work will make a significant contribution to the understanding of the Quaternary history of the forests of south-eastern Australia. Finding the location of glacial refugia is crucial to the development of long-term conservation strategies, as they are areas of high genetic and species diversity. Understanding the evolutionary processes that affect genetic diversity and gene flow of these keystone species (Nothofagus cunninghamii, N. moorei, Acacia melanoxylon, Eucalyptus viminalis) will help their long-term management.Read moreRead less

A major international eucalypt genomic project is underway. Australia needs to take part because the Australian public would expect Australia to be at the forefront of research on one of its national symbols. Eucalypts are critically important to biodiversity and commercial forestry. The development of the proposed generic eucalypt DArT chip will help keep Australia at the forefront of genetic and genomic research in eucalypts and help develop our biotechnology industry. Such research is essential for future forest tree breeding. Furthermore, eucalypt forests are one of our most important natural assets and their continual preservation requires that we develop better knowledge of their natural genetic variation and development.Read moreRead less
Molecular pathways controlling light-regulated development in legumes. Legumes are widely grown as forage and grain crops and make a substantial contribution to the Australian economy. Light is an important determinant of plant architecture and productivity and we need to know more about how development is regulated by light in this important plant group. The natural light environment faced by plants is complex and varies with crop density, season and time of day.

Legumes are widely grown as forage and grain crops and make a substantial contribution to the Australian economy. Light is an important determinant of plant architecture and productivity and we need to know more about how development is regulated by light in this important plant group. The natural light environment faced by plants is complex and varies with crop density, season and time of day. Understanding the interaction of photoreceptors and plant hormones in the control of growth is vital for manipulating crops to meet changing agronomic requirements. Training of students in state-of-the art techniques and the generation of new germplasm for use by other researchers and plant breeders will be other significant outcomes of the project.Read moreRead less

In order to study such processes our collective experience strongly suggests and increasing need for geographic amalgamation of necessary and complementary molecular and biomedical techniques. We therefore request funding to establish a collaborative research laboratory in a novel research field - Evolutionary Immuno-Ecology- in which all vital aspects, from a mechanistic to an evolutionary level, can be studied at one research centre.Read moreRead less

Meiotic recombination is a key source of the genetic variation upon which evolution thrives. This project aims to exploit new genomic resources to provide the first detailed study of recombination in Australia’s iconic Eucalypts and clarify its evolutionary role. This project will study: variation in the rate of recombination along the 11 Eucalypt chromosomes, and determine genome features which are associated with ‘hotspots’ and ‘coldspots’ of recombination; the patterns of variation in recombination rate between species, genotypes, sexes and chromosomes; and, whether the environment and population history affect recombination and thus evolvability of natural populations.Read moreRead less
