| Bovie and Hughes found that a sublethal dose of UV rays at 280 nm inhibited cell division of Paramecia. |
| In many systems, sublethal oxidative stress was found to be involved either directly or indirectly in PCD processes. |
| In the past, these parameters have been chosen with limited insight into the lethal and sublethal injury that may occur on a cellular level. |
| Other work in this field has focused on cellular and enzymatic biomarkers as indicators of sublethal effects. |
| What is the nature of the damage inflicted by mechanical stress and how can this damage, including sublethal damage to cells, be detected? |
| There was no sublethal damage to the one-day-old plants, which were all killed when attacked. |
