Project description:In this study, carbon-ion beams generated via the heavy-ion medical accelerator in Chiba (HIMAC) were targeted to growing rice seedlings (7-days-old) to examine their effect on this genome model. Both physiological parameters, such as growth, and molecular events, specially the gene expression profiles were examined immediately after irradiation (at 270 Gy dose) by rice oligo (22K) DNA microarrays. Genome-wide transcriptional profiling of radiation-response genes in rice provides us with first report on how our radioactive environment affects a plant species. Experiment Overall Design: An in vivo 7-days-old rice seedling model system was used, where whole seedlings were used for exposure to the emitted radiation from HIMAC (carbon ion beams). Dye-swap or reverse labeling with Cy3 and Cy5 dyes procedure was applied followed by hybridization and wash processes, and the hybridized microarrays (G4138A) were scanned using a GenePix microarray scanner followed by the Gene Pix 4000 analysis application program for image analysis and data extraction processes. The GeneSpring Ver. 4 software was used for normalization.

Project description:Rice (Oryza staiva) is staple food for the human consumption and model plants for genetic and molecular studies. Only few studies have been conducted on ultraviolet-B (UV-B) stress on rice. UV-B stress effects different morphological and physiological changes in plants. However, underlying mechanisms governing these integrated responses are unknown. In this study, we conducted proteomic response of rice leaves to UV-B stress using two-dimensional gel electrophoresis and identified the selected proteins by mass spectrometry analysis. To identify changes in protein accumulation in response to UV-B stress, two cultivars, i.e., IR6 and REX were irradiated by artificial UV-B radiation. Four 4 levels of daily biologically effective UV-B radiation intensities, 0 (control), 5, 10, and 15 kJ m-2 d-1 were imposed. We conducted this experiment in Sunlit Soil-Plant-Atmosphere-Research (SPAR) chambers to mimic the natural environment.

Project description:Fairy rings are zones of stimulated grass growth by the interaction between the fungi and the plant. In the previous research, we reported the identification of the “fairy”, 2-azahypoxanthine (AHX), produced by the fairy ring-forming fungus and the mechanism of its growth-promoting activity using DNA microarray. We discovered AOH, a common metabolite of AHX in plants. We investigate expression profiling of rice seedlings treated with AHX or AOH for the mechanism of their growth-promoting activity.

Project description:Autotoxicity plays an important mechanism in regulating plant productivity. Ferulic acid (FA) is phytotoxic and was identified in extracts and residues of rice plants as a candidate for rice allelochemicals. To help characterize the autotoxicity mechanism of rice, we present the first large-scale, transcriptomic analysis of rice root responses to ferulic acid.
