Other claims from this paper (7)
- Mechanism A damage signal is transferred from irradiated cells to shoot and root apical meristem cells and causes developmental alterations in Arabidopsis.
- Association The effects are associated with enhanced generation of reactive oxygen species in Arabidopsis.
- Association The effects are associated with decreased auxin-dependent transcription in Arabidopsis.
- Intervention effect Dimethyl sulfoxide, a ROS scavenger, can significantly reverse the alterations in postembryonic development and auxin-dependent transcription.
- Intervention effect Synthetic auxin 2,4-D can significantly reverse the alterations in postembryonic development and auxin-dependent transcription.
- Mechanism ROS and auxin-dependent transcription processes are suggested to play essential roles in the radiation-induced long-distance bystander effects.
- Observation Long-distance bystander/abscopal effects exist in intact Arabidopsis seeds.
