A higher ethylene concentration under
flooding increases the sensitivity of adventitious root-forming
tissues and plays a principal role in aerenchyma formation.
Waterlogging stress during formative phase caused 13.00,
21.63, 26.52 and 42.5 % reductions in plant height, tiller
production, leaf area and total biomass respectively. Anaerobic
polypeptides (ANPs) recently reported have shown to be
involved in the pathwayswhich mobilize sucrose or starch for
ethanol fermentation, which is necessary to maintain energy
production under anaerobic conditions.
