چکیده انگلیسی
Carbon ion beams irradiation as an important type of ionizing radiation is one of the major approaches used to create mutants in plants. This study investigated the role of carbon ion beams irradiation in mitigating cold stress in Arabidopsis thaliana seedlings. The results showed that 50-Gy carbon ion beam irradiation appeared stimulatory effects on root length and fresh weight in Arabidopsis seedlings under cold stress. In comparison with control, the content of hydrogen peroxide, the production rate of superoxide anion radical, hydroxyl radical generation activity, and malondialdehyde content were obviously decreased in 50-Gy carbon ion beam irradiated seedlings in response to cold stress. Moreover, irradiated 50-Gy carbon ion beam in Arabidopsis seedlings were significantly triggered the efficiency of antioxidant under cold stress. Furthermore, we investigated the expression of cold-related genes in irradiated and non-irradiated samples. Carbon ion beams irradiation up-regulated the expression levels of C-REPEAT BINDING FACTORS (CBFs), INDUCER OF CBF EXPRESSION 1 (ICE1), ICE2, CALMODULIN-BINDING TRANSCRIPTION ACTIVATOR 3 (CAMTA3) and cold-regulated COR genes, in response to cold stress. This study suggests that low-dose carbon ion beams irradiation can modulate the physiological responses and up-regulate cold signaling genes in mitigating cold stress in the growth of Arabidopsis seedlings.
