Our aim is to design strategies to improve flooding tolerance in plants. As a first approach, we are using the Arabidopsis ADH1 gene to identify promoter elements and regulatory factors involved in low oxygen responsiveness. A good candidate for anaerobic gene regulation is the transcription factor AtMYB2 (1). A second approach is to study the physiological contribution of fermentation pathways to flooding tolerance using sense/antisense transformants and a root growth survival assay (2). In a third approach, we are sequencing random clones from an anaerobically induced Arabidopsis root cDNA library, in order to identify signal transduction components.1: Hoeren et al.(1998),Genetics 149: 479 2: Ellis et al.(1999),Plant Phys. 199: 57
