Abstrakt		The metabolism of the plant growth regulator jasmonic acid was studied in liquid cultures of Pisolithus tinctorius and Laccaria laccata. After 1 week of fermentation metabolites of jasmonic acid could be detected only in minute amounts in Laccaria laccata, whereas P. tinctorius converted 20 % of the jasmonic acid into 7-iso-cucurbic acid ( 14 %), 6-epi-7-iso-cucurbic acid (4 %) and cucurbic acid (2 %) by reducing the keto group of the jasmonic acid. The preferred configuration of the formed hydroxyl group is (6S). A possible role of this metabolic activity in mycorrhization steps was discussed. In the chloroform extract 24-methyllanosta-8, 24(24')-diene-3,22-diol could be found as a characteristic compound of the fungus.
