Evidence: 100 • authority: 72

Radioresistance is the level of ionizing radiation that organisms are able to withstand. Ionizing-radiation-resistant organisms (IRRO) were defined as organisms for which the dose of acute ionizing radiation (IR) required to achieve 90% reduction (D10) is greater than 1,000 gray (Gy) Radioresistance is surprisingly high in many organisms, in contrast to previously held views. For example, the study of environment, animals and plants around the Chernobyl disaster area has revealed an unexpected survival of many species, despite the high radiation levels. A Brazilian study in a hill in the state of Minas Gerais which has high natural radiation levels from uranium deposits, has also shown many…

Different expression of miRNAs targeting helicases in rice in response to low and high dose rate γ-ray treatments.. Ionizing radiation currently represents an important tool to generate genetic variability that does not exist in nature, especially in plants. Even so, the radiological protection still represents a subject of regulatory concern. In plants, few reports dealing with the effects of γ-rays, in terms of dose rate (rate of energy deposition) and total dose (energy absorbed per unit mass), are available. In addition, plants are known to be more radioresistant than animals. The use of ionizing radiations for studying various aspects of transcription regulation may help elucidate some…

Antioxidant Defenses and Poly(ADP-Ribose) Polymerase (PARP) Activity Provide "Radioresilience" Against Ionizing Radiation-Induced Stress in Dwarf Bean Plants.. Exposure to ionizing radiation (IR) poses a significant risk for all organisms. Although plants are generally more resistant than animals, radiation still impacts their structure and function. Plant resistance to ionizing radiation is a pivotal property to guarantee their survival. This study evaluates bean leaves' early and long-term responses to oxidative stress induced by ionizing radiation. To assess the early response, we measured a battery of photosynthetic efficiency and oxidative stress markers after exposure of dwarf bean pl…
