In contrast, roots of plants adapted to waterlogging have been shown to contribute to increases in soil redox potential, by oxygen diffusion from the roots into the soil via aerenchyma (Armstrong et al.

Several traits that appear to be adaptive in wetland situations are common in these clades: rhizomatous growth form that allows rapid colonization of standing water; aerenchyma tissue in roots, rhizomes and culms, allowing tolerance of the anaerobic conditions at submerged sites; and inflated perigynia giving the buoyancy necessary for water dispersal.
