Development of Novel Pesticidal Agents. We have discovered a family of naturally occurring plant proteins called the cyclotides that have potent insecticidal activity against Helicoverpa species, one of the major pests on cotton and corn in Australia and world wide. Preliminary evidence has shown that they also have activity against major pests to livestock in Australia, including sheep blowflies. To develop these proteins as potential pesticidal agents it is necessary to understand the struct ....Development of Novel Pesticidal Agents. We have discovered a family of naturally occurring plant proteins called the cyclotides that have potent insecticidal activity against Helicoverpa species, one of the major pests on cotton and corn in Australia and world wide. Preliminary evidence has shown that they also have activity against major pests to livestock in Australia, including sheep blowflies. To develop these proteins as potential pesticidal agents it is necessary to understand the structural basis for their activity. We will do this by chemically synthesising peptides with selected residues mutated to determine their effects on activity.Read moreRead less
Environmental contamination and pig disease: an Australian microbe evolves. The Australian pig industry produces pork commodities from over 4.75 million pigs per year. Infectious diseases in industrial-scale piggeries can have a devastating effect on pork production, particularly on feed conversion efficiency and growth rates, and can pose downstream environmental contamination and food safety risks. This project aims to assess a current infectious disease problem in pigs by studying a microbe t ....Environmental contamination and pig disease: an Australian microbe evolves. The Australian pig industry produces pork commodities from over 4.75 million pigs per year. Infectious diseases in industrial-scale piggeries can have a devastating effect on pork production, particularly on feed conversion efficiency and growth rates, and can pose downstream environmental contamination and food safety risks. This project aims to assess a current infectious disease problem in pigs by studying a microbe that appears to have uniquely evolved in Australia. These results could inform the rational design of monitoring, prevention and treatment strategies to minimise infection outbreaks in Australian pigs and may result in production benefits to the pork industry, reduced environmental microbial contamination and safer food.Read moreRead less
