Abstrakt     Jasmonates are known to be widespread among plants and fungi. Their endogenous levels increase during senescence in plants. The aim of our was to define the action of the fungi in the presence of high concentrations of jasmonic acid (JA), which is known to increase in senescence. In experiments with hyphae suspension cultures of Laccaria laccata with 5.0 micro M JA we showed that the fungus decreased this concentration by 20% in one week. This layer chromatography was used for the detection of JA. As it is known, JA was detected only in non-mycorrhizal roots, but none in mycorrhical roots. We suggest that the mycorrhizal fungus restricts the jasmonic acid present in the roots and limits senescence.
