Plant Development: From Cell Fate to Organ Formation
Year: 2001
Type: article
Abstract: An excellent workshop under this title was held on the island of Capri from October 21 to 24, 2000. It was organized by Chris Bowler and Roberto Defez, as the 13th Meeting of the International Institute of Genetics and Biophysics (IIGB, Naples, Italy), and brought together plant developmental biologists covering a diverse set of topics, which were actually much broader than betrayed by the title. This report summarizes the presentations at the workshop, which was made possible through financial support from the European Union. Hormones control not only many aspects of development, but also responses of plants to the environment. One of the emerging themes is the convergence and interaction of several hormone pathways. Jérôme Giraudat (Gif-sur-Yvette) discussed several genetic screens to identify new Arabidopsis loci mediating the responses to the hormone abscisic acid (ABA). Screens for enhancers and suppressors of ABA insensitive mutants led to the isolation of ethylene response mutants. Incorporating recent work from several laboratories, Giraudat presented a model in which ABA acts downstream of hexose sensing to affect seed germination, and the effects of ABA are modulated both by gibberellins and ethylene.
