Abstract
L-methionine inhibits development of powdery mildew on cucumber leaf discs, floating on a 8×10−4 M solution of this compound. All other natural amino acids are ineffective in this way. This effect was reversed by 10−4 M folic acid. The possible interference of L-methionine with folic acid metabolism, and its importance for powdery mildew development are discussed.
Samenvatting
L-methionine verhindert de ontwikkeling van meeldauw op schijfjes komkommerblad, die op een 8×10−4 M oplossing van deze verbinding drijven. Alle andere naturrlijke aminozuren zijn in dit opzicht onwerkzaam. Een antagonering van dit effect werd verkregen door 10−4 M folinezuur aan de oplossing toe te voegen. De mogelijke invloed van L-methionine op de folinezuurstofwisseling en de gevolgen hiervan voor de ontwikkeling van meeldauw worden besproken.
