| Surprisingly, the bulk of leaf tissue remained green and without visible etiolation under anoxia. |
| Lack of oxygen or anoxia is a common environmental challenge which plants have to face throughout their life. |
| We screened several hundred inbred and exotic maize lines for their tolerance to anoxia. |
| Tolerance to anoxia is relevant to wetland species, rice cultivation and transient waterlogging of agricultural crops. |
| The anoxia probably prevented active and continuous bioturbation of the sediment. |
| Therefore, it is not possible to estimate by extrapolation the O 2 concentration in the water resulting in anoxia in the lacunae. |
