Project description:Analysis of 96-hours-old-rice seedlings with promoted-growth induced by implantation with low-energy nitrogen ion beam. Ion-beam implantation can induce changes in 351 up-regulated transcripts and 470 down-regulated transcripts, including signaling proteins, kinases, plant hormones, transposable elements, transcription factors, non-coding protein RNAs, secondary metabolites, resistance proteins, peroxidase, chromatin modification and even miRNAs. Results provide insight into the molecular basis of biological effects of plants that implanted by ion beam. Three sample groups—the controls, the ion-beam implanted samples and vacuum-treated samples. Three replicates were included in each sample group. Radiation induced gene expression rice seedlings was measured at 96 hours after germination of the seeds.

Project description:Linear energy transfer (LET) is an important factor affecting several aspects of the irradiation effect, e.g. cell survival and mutation frequency, making the heavy-ion beam an effective mutagen. To study the mechanisms behind LET-dependent effects, expression profiling was performed after heavy-ion beam irradiation of imbibed rice seeds. Array-based experiments at three time points (0.5, 1, 2 h after the irradiation) revealed that the number of up- or down-regulated genes was highest 2 h after irradiation. Array-based experiments with four different LETs at 2 h after irradiation identified LET-independent regulated genes that were up/down-regulated regardless of the value of LET; LET-dependently regulated genes, whose expression level increased with the rise of LET value, were also identified.

Oryza sativa L. 'Nipponbare' seeds were imbibed for 3 days. The seeds were irradiated with 22.5 or 50 keV/μm C-ion at a dose of 15 Gy. Gene expressions of irradiated and unirradiated embryos were measured at 0.5, 1, and 2 hours after irradiation. Three independent experiments were performed at each time and LET.
