Expression data from rice leaves treated or not with fungal elicitors and high-throughput pyrosequencing of endogenous small RNAs from Oryza sativa

Project description:High-throughput sequencing of small RNAs from rice was used to identify distinct miRNAs that are responsive to elicitors from the fungal pathogen Magnaporthe oryzae. [Expression profiling by array] We used microarrays to determine the expression behaviour of target genes for elicitor-regulated miRNAs. [High throughput sequencing] High-throughput sequencing of rice small RNAs was performed in two different tissues, leaves and roots, and two different time point of elicitor treatment, 30' and 2h Amplicons were prepared by 5M-BM-4and 3M-BM-4adaptor ligation in which the 5'-adaptor contained a 'barcode' consisting of a 4-nucleotide identifier sequence for each sample. The libraries containing unique barcodes were combined and subjected to pyrosequencing (454 Life SciencesTM, Roche) [Expression profiling by array] Leaves from rice plants were harvested at two time points after the onset of treatment (30' and 2h) with elicitors of Magnaporthe oryzae 18.1 and used for RNA extraction and hybridization on Affymetrix microarrays. Mock inoculations were performed with sterile water for control experiments. Three biological replicates were analyzed. Each sample represented a pool of approximately 150 rice plants. [High throughput sequencing] 8 samples examined: leaves and roots, treated or not with elicitors at two different time points, 30' and 2h (2x2x2)

Twig age-dependent negative correlation between Taxol accumulation and endophytic fungal assembles provide insights into screening efficient Taxol-related fungal elicitors

Project description:We identified two effective fungal elicitors, L01 (Guignardia) and J02 (Diaporthe). The two fungal elicitors might activate Taxol biosynthesis by regulating the MYC2a-controlled JA signaling pathway.

Bacterial lipopolysaccharides induce defense responses associated with Programmed cell death in rice cell

Project description:PAMP (Pathogen-Associated Molecular Pattern) recognition plays an important role in innate immune responses both in plants and animals. Lipopolysaccharides (LPS) of gram-negative bacteria are a typical PAMP molecule and have been reported to induce defense-related responses such as suppression of hypersensitive responses, defense gene espression and systemic resistance in plant. However the detailed analysis of these cellular responses and the molecular machinery involved in the perception and transduction of LPS molecule largely remains to be studied. Furthermore, the biological activities of LPS on plants have so far been reported only for dicots and no information is available on the action of LPS on monocots. We report here that bacterial LPSs, both from plant pathogens and non-pathogens, could induce various defense responses in rice cells, including reactive oxygen generation and defense gene expression. Global analysis of gene expression induced by two PAMP elicitors, LPS and chitin oligosaccharide elicitor, showed a close correlation between the gene responses induced by these elicitors, indicating the convergence of signaling cascades downstream of corresponding receptors. Further, we show that the defense responses induced by LPS are associated with programmed cell death, a finding so far not reported for LPS action on plant cells.

Expression data in response to Xoo. bacterial infection in rice

Project description:In response to bacterial infection, early transcriptional re-programming occurs in the host plant. We used microarrays to analyse the global transcriptomic response to Xoo. infection in a resistant rice cultivar (IR24). This was analysed in parallel with microarrays examining Xoo infection in a susceptible rice cultivar (IRBB21) as well as in response to Xoc [GSE19239], viral [GSE11025], parasite [GSE10373] and fungal [GSE7256, GSE18361] infections in rice, in order to identify common and distinct responses to biotic stress.

Transcriptomic study of the impact of iron toxicity on rice plant

Project description:transcriptomic study of the impact of iron toxicity on rice plant (Oryza sativa L.; cv ‘I Kong Pao’ ) after short term (3 days) or long term (3 weeks) exposure to ferrous iron (125 ppm). Twenty five days old rice seedlings were exposed to 0 or 125 mg/L ferrous iron for 3 days and 3 weeks in hydroponic culture. Comparison between control and iron stressed plants were done at the shoot and the root levels. The assays were replicated twice on two independent plant cultures.
