title: Induction of resistance of wheat plants to pathogens by pretreatment with N-methylated substances.
abstract: It has been established that the application of N-methylated compounds as N, N-dimethyl-L-tyrosine and glycine-betaine can induce resistance to biotrophic fungi (Erysiphe graminis, Puccinia recondita) in wheat (Yubileynaya) at two different pretreatment concentrations. This dose-dependent "double immune response" of plants is the basic phenomenon of the biochemical immunization. These N-methylated compounds are potential formaldehyde generators and the formaldehyde formed can take part in the induction of resistance of wheat plants. It seems that the dose-dependent "double immune response" of plants is in correlation with the biotransformation steps of formaldehyde cycle as a fundamental biochemical pathway.
