| It has been widely suggested that phellem, a corky outer layer derived from the cork cambium may function as aerenchyma, but until now no-one had tested that hypothesis. |
| Programmed cell death also takes place in the cortex of adventitious roots to form aerenchyma. |
| An example of this kind of adaptation is the formation in aquatic plants of an especially porous plant tissue called aerenchyma. |
| Finally, long-term morphological changes are induced, such as the formation of lenticels and aerenchyma to improve the oxygen permeability of the tissue. |
| Fusoid cells are characteristically found only in bamboos, and have been considered as aerenchyma tissues. |
| Extensive aerenchyma tissues in the cortex permit the rice plant to persist in very poorly drained soils. |
