Clay nanoparticle-facilitated RNAi for non-transgenic modification of crops. This project aims to define the most effective spray formulations, consisting of clay nanoparticles and induced RNA interference (RNAi) to manipulate gene expression in plants. Topical application of double-stranded RNA (dsRNA) for RNAi represents an attractive alternative to genetically engineered crops. However, naked dsRNA is unstable and is not efficiently taken up by plants. For these reasons, topical application o ....Clay nanoparticle-facilitated RNAi for non-transgenic modification of crops. This project aims to define the most effective spray formulations, consisting of clay nanoparticles and induced RNA interference (RNAi) to manipulate gene expression in plants. Topical application of double-stranded RNA (dsRNA) for RNAi represents an attractive alternative to genetically engineered crops. However, naked dsRNA is unstable and is not efficiently taken up by plants. For these reasons, topical application of dsRNA has thus far produced only modest induction of RNAi in plants. Nanoparticle-facilitated manipulation of gene expression in plants will enable sustainable clean green strategies for protecting crops from diseases. This project will result in improved crop protection and productivity and boost the export potential of Australian crops.Read moreRead less
The genes and pathways regulated by the AMYB80 network are involved in Arabidopsis pollen development. Tapetum is the inner layer of an anther essential for pollen formation. The project will study tapetal AtMYB80 network regulating pollen development. Knowledge of the network will be important in developing means to protect crop yields against cold and drought. Regulation of AtMYB80 activity is being used to create hybrid crops of high productivity.
Nanoliposomal delivery of docosahexaenoic acid (DHA) to neuronal cells. Omega-3 fatty acids such as docosahexaenoic acid (DHA) are essential for brain function. They are effective as adjunct treatments for depression, but at high doses. The project will develop nanoliposomes to target delivery of DHA to brain cells. Efficient delivery of DHA to brain cells will increase its effectiveness as a dietary supplement and lessen the burden of disease.
