Different expression of miRNAs targeting helicases in rice in response to low and high dose rate γ-ray treatments.

ABSTRACT: 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 of the unanswered questions regarding DNA repair in plants. Under these premises, microRNAs have emerged as molecules involved in gene regulation in response to various environmental conditions as well as in other as
