Abscisic acid (ABA) was the last major hormone to be identified, although its existence had been forecast for some time. Groups lead by Addicott studying hormonal relationships in cotton (Ohkuma et al., 1963) And Wareing studying dormancy in woody perennials independently identified Abscisin II in cotton and Dormin in woody plants (Corniforth et al., 1965). The two compounds were ultimately determined to be identical and were given the name Abscisic acid in 1967 at a plant hormone conference in Ottawa, Canada.
