10-Oxo-trans-8-decenoic acid (ODA): production, biological activities, and comparison with other hormone-like substances in Agaricus bisporus.

The few well-characterized fungal growth-regulating substances include 10-oxo-trans-8-decenoic acid (ODA) and hercynine. This report deals with production and tissue location of ODA. It also describes some biological activities of addition of ODA, hercynine and cytokinins on growth and postharvest morphogenesis of mushrooms. Production of ODA in sporophore extracts was limited mainly by oxygen availability and the possible occurrence of a competitive metabolic pathway. Presumably synthesized within the stipe and skin tissues, ODA accumulated in the gills. Mycelium growth rate on a potato-based medium was significantly increased in the presence of ODA. Moreover, stipe lengthening was slightly stimulated by 10 or 100 micro M ODA. ODA appeared poorly active, and mycelium growth on asparagine-glucose medium was strongly inhibited by 200 micro M ODA. In contrast with cytokinins or hercynine, ODA did not speed up cap opening. Finally, tests carried out on animal cells suggested a dose-dependent cytoto

xic effect of ODA.
