Radiata pine is Australia's premiere softwood plantation species occupying in excess of one million hectares, contributing over $18 billion to Australia's GNP and providing employment to 130,000 Australians. With a trade deficit in forest and forest products of $1.85 billion, current massive plantation establishment efforts are in train to reverse this trend. These have to be backed by research into the factors that determine the base resource's quality, growth and sustainability. Results will lead to improved resource quality, increased productivity and new industrial opportunities, directly improving our trade position and releasing pressure on our native forest resources.Read moreRead less
Mechanistic characterisation of genotype x environment interactions in sorghum and arabidopsis. Sorghum is an economically important cereal crop for Australia. In Australia, sorghum is used as a staple animal feed and it is very important for the live stock industry. With the predicted changes of temperature and rainfall patterns due to climate change, negative effects on sorghum yield are expected, which can have adverse effects on Australian economy. Our studies will identify and mark genes th ....Mechanistic characterisation of genotype x environment interactions in sorghum and arabidopsis. Sorghum is an economically important cereal crop for Australia. In Australia, sorghum is used as a staple animal feed and it is very important for the live stock industry. With the predicted changes of temperature and rainfall patterns due to climate change, negative effects on sorghum yield are expected, which can have adverse effects on Australian economy. Our studies will identify and mark genes that regulate flowering and seed production in sorghum in response to changes in temperature and light interactions. These studies will help to develop novel sorghum varieties with desirable characters through plant-breeding programmes.Read moreRead less
Identification of genes controlling wood fibre properties in Eucalyptus nitens. Australian forestry is shifting to high intensity eucalypt plantations and increasingly focussing on development of breeds and clones with superior wood and pulp traits. Many of these traits are under moderate to strong genetic control and DNA markers have helped identify regions on eucalypt chromosomes that influence these traits. This project aims to identify the genes at these chromosomal locations that influence ....Identification of genes controlling wood fibre properties in Eucalyptus nitens. Australian forestry is shifting to high intensity eucalypt plantations and increasingly focussing on development of breeds and clones with superior wood and pulp traits. Many of these traits are under moderate to strong genetic control and DNA markers have helped identify regions on eucalypt chromosomes that influence these traits. This project aims to identify the genes at these chromosomal locations that influence wood fibre development and which have a strong influence on major commercial traits. The project will increase our understanding of wood and fibre development in eucalypts, and facilitate development of genetic markers to track superior genes during breeding.Read moreRead less
Understanding the differentiation of the endocardium. The project aims to understand the genetic regulation of endocardial development. The heart is essential for survival, its beat the indicator of life. The endocardium, the heart’s inner lining, is required for signalling during heart development and is a major component of the valves, septa and trabeculae. Despite its indispensable role, little is known about how it forms or develops. This project integrates two complementary approaches that ....Understanding the differentiation of the endocardium. The project aims to understand the genetic regulation of endocardial development. The heart is essential for survival, its beat the indicator of life. The endocardium, the heart’s inner lining, is required for signalling during heart development and is a major component of the valves, septa and trabeculae. Despite its indispensable role, little is known about how it forms or develops. This project integrates two complementary approaches that have identified the earliest marker of endocardial differentiation and devised the method to make endocardium from stem cells. Knowledge from this work will inform future research into growing and regenerating damaged tissue.Read moreRead less
Identifying genes causing thermal evolution of ectotherm body size. Cold-blooded animals increase in body size as they are found in populations at greater distances from the equator. These patterns are due to populations adapting to temperature. The aim of this project is to identify the genes involved in this adaptation process. We will do this by taking advantage of a well-studied body size cline in the vinegar fly on the east coast of Australia, and by building on an international collaborati ....Identifying genes causing thermal evolution of ectotherm body size. Cold-blooded animals increase in body size as they are found in populations at greater distances from the equator. These patterns are due to populations adapting to temperature. The aim of this project is to identify the genes involved in this adaptation process. We will do this by taking advantage of a well-studied body size cline in the vinegar fly on the east coast of Australia, and by building on an international collaboration between a leading UK and two Australian research groups. In doing so we will provide an explanation at the molecular level for one of the great unresolved phenomena in biology: why do cold-blooded animals get bigger in the cold? The research also leads to the potential to manipulate body size in animals.Read moreRead less
Kruppel-like factors and the methylome. This project aims to test the hypothesis that the KLF/SP family of transcription factors work in part via dynamic interactions with methylated cytosine nucleotides in DNA. This is fundamental to their function as pioneer factors in reprograming and their ability to co-ordinate differentiation and organogenesis. Conversely, dynamic changes in methylation status engage or disengage new regulatory elements in the genome via recruitment of KLF/SP family protei ....Kruppel-like factors and the methylome. This project aims to test the hypothesis that the KLF/SP family of transcription factors work in part via dynamic interactions with methylated cytosine nucleotides in DNA. This is fundamental to their function as pioneer factors in reprograming and their ability to co-ordinate differentiation and organogenesis. Conversely, dynamic changes in methylation status engage or disengage new regulatory elements in the genome via recruitment of KLF/SP family proteins as specific effectors. This project will address a new paradigm in genetics that is likely to underpin development.Read moreRead less

Most human traits have a genetic component and display substantial diversity within and among populations. How natural selection changes and maintains genetic variation in human traits is a long-standing question in evolution that the proposed project aims to answer. Using innovative statistical methods and largest genomic “big” datasets ever across populations of different ancestral backgrounds, this project expects to generate new knowledge on the roles of natural selection in shaping the genetic variation in traits and identify key factors that drive the differentiation of human populations. These outcomes will significantly improve our understanding on the evolution of human traits and adaptation of populations to changing environments.Read moreRead less
Why is most of the genetic variance for complex traits undetected by large powerful screens of common variants? The genomics revolution has made it possible to measure thousands of DNA variants in individuals. These variants have been associated with phenotypic outcomes in a range of species. Paradoxically, even very large studies have only accounted for a fraction of the resemblance between relatives that we know exist. Our study will test three specific hypotheses to explain this paradox. A be ....Why is most of the genetic variance for complex traits undetected by large powerful screens of common variants? The genomics revolution has made it possible to measure thousands of DNA variants in individuals. These variants have been associated with phenotypic outcomes in a range of species. Paradoxically, even very large studies have only accounted for a fraction of the resemblance between relatives that we know exist. Our study will test three specific hypotheses to explain this paradox. A better understanding about the genetic architecture for complex traits will improve the efficiency of gene mapping methods, including applications in humans for traits related to productive ageing and a healthy start to life, will lead to more efficient selection programs in agricultural populations and will inform us with respect to past evolutionary events.Read moreRead less
