Zearalenone and flower bud formation in thin-cell layers of Nicotiana tabacum L.

Three lines of evidence indicated a connectionbetween zearalenone (ZEN) and flower bud formationin thin cell layer (TCL) explants of Nicotianatabacum L. cv. Samsun. (1) There were two peaks inthe endogenous ZEN level during the formation offlower buds. (2) The specific inhibitor of ZENbiosynthesis, malathion (MAL), inhibited thebiosynthesis of endogenous ZEN and at the same timeflower bud neoformation. (3) Exogenous ZEN inducedflower bud neoformation.
