The role of phytotoxins in ray blight disease of pyrethrum and significance of toxin tolerance to disease resistance. Ray blight disease, caused by Phoma ligulicola, is the greatest threat to the Australian pyrethrum industry causing $2.0M in annual losses. We aim to clarify the pathology of P.ligulicola in pyrethrum, focussing on the role of fungal toxins during infection. Toxin importance in disease will be determined through histology and induction of toxin- pathogen mutants. Toxins will be ....The role of phytotoxins in ray blight disease of pyrethrum and significance of toxin tolerance to disease resistance. Ray blight disease, caused by Phoma ligulicola, is the greatest threat to the Australian pyrethrum industry causing $2.0M in annual losses. We aim to clarify the pathology of P.ligulicola in pyrethrum, focussing on the role of fungal toxins during infection. Toxin importance in disease will be determined through histology and induction of toxin- pathogen mutants. Toxins will be characterised and used in tissue culture to select obtain toxin tolerant pyrethrum clones that will be evaluated for agronomic performance and disease resistance. Successful development of resistant clones will decrease production costs, minimise risk of fungicide resistance development and reduce environmental pollution.Read moreRead less

Summary
Purchase of a Benchtop Triple Quadrupole Gas Chromatograph Mass Spectrometer. This submission seeks funding to replace the existing 18 year old bench top gas chromatography/mass spectrometry instrument with a modern instrument, so providing the research community with a facility capable of meeting the increasingly more demanding analytical requirements of current research projects. The requested instrument will make a substantive contribution to improving research output. In comparison with th ....Purchase of a Benchtop Triple Quadrupole Gas Chromatograph Mass Spectrometer. This submission seeks funding to replace the existing 18 year old bench top gas chromatography/mass spectrometry instrument with a modern instrument, so providing the research community with a facility capable of meeting the increasingly more demanding analytical requirements of current research projects. The requested instrument will make a substantive contribution to improving research output. In comparison with the existing instrument it will be 2 orders of magnitude more sensitive, enable an additional two forms of ionisation, have the capacity to perform 3 additional types of mass spectrometry experiments and will have manufacturer spares support.Read moreRead less
