Abstract: Despite knowledge on the responses elicited in plants shortly after exposure to ionising radiation (IR), there is, so far, very little information on the effects elicited when plants are allowed to recover from irradiation. Such recovery studies are vital as they may help to not only determine the long-term consequences of radiation exposure in plants, but also, provide more insight into the mechanisms underpinning plant responses to IR. This PhD project demonstrates that both Arabidopsis and rice plants are able to recover from radiation exposure through overall molecular influence of growth, development and the physiological status. We also demonstrate that under the current experimental conditions used, rice plants are not more radiosensitive compared to Arabidopsis as previously thought. Taken together, the information gained from this study will contribute towards a more comprehensive mechanistic understanding of IR-induced effects in living systems, which will allow for the strengthening of current legislation that has been formulated towards radiation protection of the environment.
