Abstract

The importance of lipid metabolism to appressorium turgor generation by the rice blast fungus Magnaporthe grisea will be investigated. The VTL1 vacuolar triacylglycerol lipase gene will be characterised by targeted gene replacement. Triacylglycerol lipase(s) will be purified from developing appressoria and characterised. The potential role of peroxisomal- beta-oxidation and the glyoxylate pathway in appressorium turgor generation will be assessed by characterisation of the non-pathogenic pth2 mutant, which lacks carnitine acyl transferase. Mutational analysis of the KAT1 and PHE1 genes which encode beta-oxidation enzymes, and the ICL1 isocitrate lyase gene will be carried out to test the hypothesis that glycerol accumulation in appressoria results predominantly from rapid vacuolar degradation of lipid bodies.
