Many wetland species form aerenchyma and a barrier to radial O(2) loss (ROL) in roots. These features enhance internal O(2) diffusion to the root apex. Barrier formation in rice is induced by growth in stagnant solution, but knowledge of the dynamics of barrier induction and early anatomical changes was lacking.
