This is a volatile chemical compound related to acetophenone and is a natural product that can be found in PosidoniaÃ¥ÃŠoceanica. The compound is also produced by the maleÃ¥ÃŠleaf-footedÃ¥ÃŠbug and used in its communication system. This substance is involved in plant-pathogen recognition. In vitro studies show that acetosyringone increases mycorrhizae formation in the fungus GlomusÃ¥ÃŠintraradices. Total synthesis of acetosyringone has been performed by Crawford et al in 1956.
