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.

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.

Epigenetic programming of plant sperm cells. Most of the grains and seeds that form the world's food supply are the result of the successful functioning of sperm and egg cells during fertilisation. This proposal aims to investigate the nature of sperm cell genome programming in plants and unravel molecular processes that give these cells their unique identity. This innovative and challenging research will also provide an excellent opportunity for training the next generation of scientists. The o ....Epigenetic programming of plant sperm cells.

This proposal aims to investigate the nature of sperm cell genome programming in plants and unravel molecular processes that give these cells their unique identity. This innovative and challenging research will also provide an excellent opportunity for training the next generation of scientists. The outcomes of this proposal will enhance Australia's international lead in this field and will pave the way toward the development of new approaches for sustaining and enhancing crop productivity under changing environmental conditions.

A new approach to control of plant parasitic nematodes. Plant parasitic nematodes are the fourth most important plant pathogens worldwide. The aim of this project is to develop ?proof-of-concept? of a new strategy for nematode control, based on a synthetic ?cell death? resistance gene, in which tight specificity of expression of the resistance gene is provided using two gene promoters. The work focusses on finding the best combination of promoters which are switched on by infection of plants w ....A new approach to control of plant parasitic nematodes. Plant parasitic nematodes are the fourth most important plant pathogens worldwide. The aim of this project is to develop ?proof-of-concept? of a new strategy for nematode control, based on a synthetic ?cell death? resistance gene, in which tight specificity of expression of the resistance gene is provided using two gene promoters. The work focusses on finding the best combination of promoters which are switched on by infection of plants with nematodes. It is based on an Australian patent which has wide applicability in plant biotechnology. Nematode control will benefit horticultural and broadacre farming by reducing pathogen losses and improving quality.Read moreRead less
