Cotton is poorly adapted to waterlogged conditions, and can cause significant yield loss. Cotton does not form aerenchyma and so aerobic respiration cannot proceed in the roots which must rely on anaerobic fermentation. This presentation describes research that describes the physiology, crop growth, and yield responses to intermittent waterlogging. Research assessed performance of transgenic genotypes over-expressing Pdc and Adh proteins (Increased expression of these proteins may increase alcohol fermentation), and (2) the potential of a plant ethylene inhibitor (AVG, aminoethoxyvinylglycine) applied to the crop just prior to waterlogging to reduce fruit abscission.
