• Appressorium formation in germinating conidia of Magnaporthe grisea was inhibited on inductive and on noninductive surfaces by monounsaturated fatty acids with chain lengths of 16,18,or 20 carbon atoms. On a noninductive surface, the inhibition was only observed upon stimulation with 1,16-hexadecanediol or oleyl alcohol, but not upon stimulation with 8-(4-chlorophenylthio)-adenosine-3', 5'-monophosphate. In the C_18-series, fatty acids with a double bond in position 9 were the most active ones. At 1 μg/ml of oleic or elaidic acid, less than 30% of the germinated conidia formed appressoria. The mode of inhibition was competitive to the inducing agent. On an inductive surface, compared to a noninductive surface the concentrations of oleic and elaidic acid needed for inhibition of appressorium formation were one order of magnitude higher. Methyl esters of inhibitory fatty acids and acids with two double bonds were not active. Like oleyl alcohol, elaidyl alcohol and petrosclinyl alcohol stimulated infection structure for mation on the noninductive surface.
