Small RNAs in rice cultivar Kasalath (Oryza sativa L.) induced by high temperatures during germination

Project description:The impact of global warming on weather patterns raises concerns for agriculture management. Using NGS technologies, we identified the miRNA profile that is expressed in rice cultivar grown at two different temperatures. We observed 118 and 100 miRNAs uniquely expressed at 35°C and 25°C respectively. Potential targets of these miRNAs have been identified. An interesting example, would be mir1863b which targets Os07g46670.3; a homologue of the ERD15 gene in Arabidopsis which is involved in dehydration stress response.

mRNA sequencing of whole 15 d old Oryza sativa shoots

Project description:The rice gene SUB1A-1 confers flooding tolerance restricting shoot growth during submergence. Rice with SUB1A also show more rapid recovery after submergence ends, but mechanisms by which SUB1A improves recovery from submergence had not been examined. In this study, the transcriptome was sequenced at five time points over a 24 hour submergence recovery period in near-isogenic rice genotypes with and without SUB1A.

Proteomic analysis response of rice (Oryza sativa) leaves to ultravoilet (UV-B) stress

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.

Genome-wide Expression Profiles of Drought and High-salinity Stresses-responsive Genes in Rice (Oryza Sativa L. Indica)

Project description:Three rice major tissues, namely flag leaf, shoot and panicle, were involved in this study. Each tissue had two kinds stress treatment, drought and high salinity, in 3 different time courses. For drought treated samples, an additional water recovery was applied. Each experiment had three replicates. Keywords: Comparison of gene expression in three tissues with stress treatment and without treatment To globally elucidate potential genes involved in drought and high-salinity stresses responses in rice, an oligomer microarray covering 37,132 genes including cDNA or EST supported and putative genes was applied to study the expression profiling of shoot, flag leaf, and panicle under drought or high-salinity treatment. Three rice major tissues, namely flag leaf, shoot and panicle, were involved in this study. Each tissue had two kinds stress treatment, drought and high salinity, in 3 different time courses. For drought treated samples, an additional water recovery was applied. Each experiment had three replicates.
