Abstract
The in vitro action of Taphrina wiesneri on coumarin and its related compounds were examined. Melilotic acid, which accumulates in larger amounts in infected cherry leaves than in healthy leaves, was produced from coumarin, 3,4-dihydrocoumarin, o-coumaric acid or o-coumaryl glucoside by the action of acetone-dried cells of the fungus. From the results it is suggested that in cherry plants infected with the fungus melilotic acid may be formed from these precursors contained as ordinary components in cherry leaves. Possible mechanisms of the conversion of coumarin to melilotic acid are also discussed.
