Low-level Gamma Ray Exposure to Rice Seedlings in Iitate Village (Fukushima) Activates Self-defense Responses Unraveled by DNA Microarray Analysis

ABSTRACT: In the summer of 2012, one year after the 3.11 accident at Fukushima Daiichi nuclear power plant following the Great Tohoku Earthquake, a project was initiated to examine the effects of low-level gamma radiation on rice plants. The site of the experiment was the highly contaminated Iitate village in Fukushima prefecture of Japan. The basic experimental strategy was to expose healthy rice seedlings to continuous low-dose gamma radiation and examine the morphological and molecular genetic changes therien. Selected gene expression profiles of internal control, DNA replication/repair, oxidative stress, photosynthesis, and defense/stress functions were examined by semi-quantitative RT-PCR. Results revealed that low-level gamma radiation affects the expression of numerous genes, in particular sh
