Understanding and avoiding transgene silencing in sugarcane. Sugarcane is one of the world's major crops for food (sugar) and fuel (ethanol, electricity co-generation). It is one of the most appealing target crops for metabolic engineering aimed at renewable biomaterials and biofuels. Australia has invested strongly to achieve scientific leadership in gene technologies in our major export crops including sugarcane.

Sugarcane is one of the world's major crops for food (sugar) and fuel (ethanol, electricity co-generation). It is one of the most appealing target crops for metabolic engineering aimed at renewable biomaterials and biofuels. Australia has invested strongly to achieve scientific leadership in gene technologies in our major export crops including sugarcane. Field tests show that development of methods to avoid unstable expression or 'silencing' of introduced genes is now a critical requirement for practical application. The current project emerges from industry recognition of the need to understand and avoid transgene silencing. The methods developed using sugarcane are expected to have rapid applicability for wider benefits in agriculture.Read moreRead less
eSorghum as a bio-fuel feedstock for arid environments. Increasing fuel costs, finite resources and the need to develop more carbon neutral and cleaner fuels have created a need for renewable sources. Ethanol and future generation biofuels (butanol and more energy-rich alcohols) can be extracted from biomass sources. Sorghum is an ideal bioenergy feedstock in the hotter, drier areas of Northern Australia, where starch (grain), sugar and lignocellulose (stover) can be amassed in this water effi ....eSorghum as a bio-fuel feedstock for arid environments. Increasing fuel costs, finite resources and the need to develop more carbon neutral and cleaner fuels have created a need for renewable sources. Ethanol and future generation biofuels (butanol and more energy-rich alcohols) can be extracted from biomass sources. Sorghum is an ideal bioenergy feedstock in the hotter, drier areas of Northern Australia, where starch (grain), sugar and lignocellulose (stover) can be amassed in this water efficient plant. Identifying and manipulating the genes to enable the improvement of sorghum as a dedicated bioenergy crop, will enable the increased efficiency of the Australian biofuels industry and create sustainable rural industries.Read moreRead less
Genetic transformation of the biodiesel producing tree legume Pongamia pinnata. In response to global climate change and the threat of declining reserves of fossil fuels, liquid fuels of the future are to be manufactured in greater proportion from sustainable biological resources. Pongamia, a native legume tree, has the potential to make a significantly positive impact on the emerging biofuels industry. As a legume Pongamia requires no nitrogen fertiliser, is not a food crop, and can grow well o ....Genetic transformation of the biodiesel producing tree legume Pongamia pinnata. In response to global climate change and the threat of declining reserves of fossil fuels, liquid fuels of the future are to be manufactured in greater proportion from sustainable biological resources. Pongamia, a native legume tree, has the potential to make a significantly positive impact on the emerging biofuels industry. As a legume Pongamia requires no nitrogen fertiliser, is not a food crop, and can grow well on marginal lands unlikely to be used for food crops. Improvement of Pongamia through the genetic tools developed in this project will provide an environmentally sustainable source of biodiesel long into the future.Read moreRead less
