Population dynamics and genetic variation of plants with contrasting fire responses. We combine the traditional concerns of population viability analyses with the modern techniques of DNA fingerprinting for precise genotyping of individual plants and their seeds. We expect major breakthroughs in our understanding of how fire-killed species have survived thousands of years of frequent burning by Aborigines (by identifying seeds dispersed long distances from burnt parents); how paternity of offspr ....Population dynamics and genetic variation of plants with contrasting fire responses. We combine the traditional concerns of population viability analyses with the modern techniques of DNA fingerprinting for precise genotyping of individual plants and their seeds. We expect major breakthroughs in our understanding of how fire-killed species have survived thousands of years of frequent burning by Aborigines (by identifying seeds dispersed long distances from burnt parents); how paternity of offspring changes over the lifespan of plants which retain their seeds for many years; at what age within-plant genetic variation is at a maximum as a guide to optimal fire management; and the extent that deleterious somatic mutations explain low seed set among long-lived species.Read moreRead less
Understanding the control of male germ-line development by the germline-restrictive silencing factor in plants. The world population is currently increasing at an unprecedented rate, with a concomitant requirement to double the food production from the same amount of arable land. To ensure global political and social stability, equitably increasing sustainable food production without compromising environmental integrity remains a major challenge. This proposal investigates the molecular mechanis ....Understanding the control of male germ-line development by the germline-restrictive silencing factor in plants. The world population is currently increasing at an unprecedented rate, with a concomitant requirement to double the food production from the same amount of arable land. To ensure global political and social stability, equitably increasing sustainable food production without compromising environmental integrity remains a major challenge. This proposal investigates the molecular mechanisms underlying male germ line initiation and development in plants. Switching off male gamete development in some crop plants will create male sterile lines, which, when crossed with genetically distinct lines, will have the potential to produce hybrids that yield 20-30 percent more crop without additional inputs.

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
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

Dryland salinity is an issue of national significance due to its impact on primary industries which contribute billions of dollars to our economy. However, millions of hectares of arable land are now affected by salinity, with devastating effects on crops, native plants, water quality and wildlife. This project works with the rural community and exploits the unique gene pool of certain Australian salinity-tolerant plants for environmental benefits (revegetation, salinity control) and simultaneous economic returns through using these for timber and perennial fodder. The project thus addresses the national priorities of preventing the expansion of salinity, putting it to sustainable uses and preserving biodiversity.Read moreRead less
