<h4>Background</h4>Endogenous small (sm) RNAs (primarily si- and miRNAs) are important trans/cis-acting regulators involved in diverse cellular functions. In plants, the RNA-dependent RNA polymerases (RDRs) are essential for smRNA biogenesis. It has been established that RDR2 is involved in the 24 nt siRNA-dependent RNA-directed DNA methylation (RdDM) pathway. Recent studies have suggested that RDR1 is involved in a second RdDM pathway that relies mostly on 21 nt smRNAs and functions to silence ...[more]

Project description:Plant roots are the primary site of perception and injury for saline-alkaline stress. The current knowledge of the saline-alkaline stress transcriptome is most focused on salt (NaCl) stress. Only a little alkaline (NaHCO3) stress transcriptome is limited to one time point after stress. Time-course analysis and comparative investigation on roots in the alkaline stress condition are needed to understand the gene response networks that are subject to alkaline tolerance. We used microarrays to detail the global programme of gene expression underlying NaHCO3 treatment and identified distinct classes of regulated genes during this process. Three week old Glycine soja seedling roots from 3cm root apex were harvested in two independent biological replicates after 0, 0.5, 1, 3, 6, 12 and 24h treatment with 50mmol/L NaHCO3 stress for RNA extraction and hybridization on Affymetrix microarrays. To minimize biological variance, roots from three plants originating from the same experiment, condition and cultivar was pooled.

Project description:Transcriptome of Glycine soja leaf tissue during a detailed time course formed a foundation for examining transcriptional processes during NaHCO(3) stress treatment. Of a total of 2,310 detected differentially expressed genes, 1,664 genes were upregulated and 1,704 genes were downregulated at various time points. The number of stress-regulated genes increased dramatically after a 6-h stress treatment. GO category gene enrichment analysis revealed that most of the differentially expressed genes were involved in cell structure, protein synthesis, energy, and secondary metabolism. Another enrichment test revealed that the response of G. soja to NaHCO(3) highlights specific transcription factors, such as the C2C2-CO-like, MYB-related, WRKY, GARP-G2-like, and ZIM families. Co-expressed genes were clustered into ten classes (Pâ<â0.001). Intriguingly, one cluster of 188 genes displayed a unique expression pattern that increases at an early stage (0.5 and 3 h), followed by a decrease from 6 to 12 h. This group was enriched in regulation of transcription components, including AP2-EREBP, bHLH, MYB/MYB-related, C2C2-CO-like, C2C2-DOF, C2C2, C3H, and GARP-G2-like transcription factors. Analysis of the 1-kb upstream regions of transcripts displaying similar changes in abundance identified 19 conserved motifs, potential binding sites for transcription factors. The appearance of ABA-responsive elements in the upstream of co-expression genes reveals that ABA-mediated signaling participates in the signal transduction in alkaline response. Young leaves of three-week-old Glycine soja were harvested in two independent biological replicates after 0, 0.5, 1, 3, 6, 12 and 24h treatment with 50mmol/L NaHCO3 stress for RNA extraction and hybridization on Affymetrix microarrays. To minimize biological variance, leaves from three plants originating from the same experiment, condition and cultivar was pooled.

Project description:Controversy regarding genetically modified (GM) plants and their potential impact on human health contrasts with the tacit acceptance; of other plants that were also modified, but not considered as GM products (e.g., varieties raised through conventional breeding such as mutagenesis). What is beyond the phenotype of these improved plants? Should mutagenized plants be treated differently from transgenics? We have evaluated the extent of transcriptome modification occurring during rice improvement through transgenesis versus mutation breeding. We used oligonucleotide microarrays to analyze gene expression in four different pools of four types of rice plants and respective controls: (i) a; gamma-irradiated stable mutant, (ii) the M1 generation of a 100-Gy gamma-irradiated plant, (iii) a stable transgenic plant obtained for production of an anticancer antibody, and (iv) the T1 generation of a transgenic plant produced aiming for abiotic stress improvement, and all of the unmodified original genotypes as controls. We found that the improvement of a plant variety through the acquisition of a new desired trait, using either mutagenesis or transgenesis, may cause stress and thus lead to an altered expression of untargeted genes. In all of the cases studied, the observed alteration was more extensive in mutagenized than in transgenic plants. We propose that the safety assessment of improved plant varieties should be carried out on a case-by-case basis and not simply restricted to foods obtained through genetic engineering. Experiment Overall Design: Plant Materials Experiment Overall Design: Two genetically stable Oryza sativa L. ssp. japonica lines: a gamma-irradiated ricemutant(cv. EstrelaA)and a well characterized transgenic rice line (cv. Bengal) were used as well as controls. The stable mutant was obtained in 1988 by gamma-irradiation, had already gone over 10 generations of self-pollination, and had a mature average height about 45 cm lower than the wild type. The stable transgenic line, which was already in the third generation of self-pollination after transformation, expresses a ScFV antibody (ScFvT84.66) against carcinoembryonic antigen, a well characterized tumor-associated marker antigen. Experiment Overall Design: We have also used two genetically unstable rice lines: the M1 generation of a 100-Gy gamma-irradiated line (98% survival after mutagenesis) and the T1 generation of an Agrobacterium-transformed transgenic line (both cv. Nipponbare) containing one copy of the BCBF1 gene driven by the AtRD29A promoter from Arabidopsis and one copy of the hpt II gene. We used seeds from the same self-pollinated panicle for control and irradiation/transgenesis. The unstable mutant line chosen for this experiment was the one showing a phenotype more similar to that of the nonirradiated control. Experiment Overall Design: In the case of the transgenic lines, stability was based on the stable Experiment Overall Design: inheritance of the introduced transgenes in the homozygous progeny. Regarding the mutagenized plants we have defined as genetically stable plants those that, after mutagenesis, had already gone through several cycles of self-pollination while maintaining the desirable traits. Experiment Overall Design: RNA Extraction and Microarrays Experiment Overall Design: Two pools of six whole seedlings were prepared for each condition under test, and RNA was isolated with the RNeasy Plant Mini Kit (Qiagen) following the manufacturerâ??s instructions. Total RNA was kept at -80°C and sent to the Affymetrix core facility (Instituto Gulbenkian de Ciência, Experiment Overall Design: Oeiras, Portugal), where quality-control analysis was carried out before cDNA synthesis from themRNA[with appropriate oligo(dT) primers], labeling (through synthesis of cRNA with incorporation of biotinylated ribonucleotide analogs), and hybridization to the GeneChip Rice Genome Array (Affymetrix). This array contains probes to query 51,279 transcripts representing two rice subspecies (48,564 japonica transcripts and 1,260 transcripts of indica subspecies). Experiment Overall Design: Data Analysis Experiment Overall Design: Microarrays data analysis was performed with Partek Genomics Suite software. Affymetrix CEL files were imported by using the Robust Multichip Average method, which involves four steps: background correction of the perfect match values, quintile normalization across all of the chips in the experiment, Log2 transformation, and median polish summarization. The logged data were used for hierarchical cluster analysis and statistical analysis. Experiment Overall Design: Hierarchical cluster analysis was performed by using Pearsonâ??s dissimilarity product moment correlation coefficient and Wardâ??s algorithm. Experiment Overall Design: For the identification of differentially expressed genes we used ANOVA Experiment Overall Design: and a false discovery rate with a 0.05 threshold.

Project description:Hydrogen peroxide (H2O2) can act as a signaling molecule that influences various aspects of plant growth and development, including stress signaling and cell death. Catalase deficient plants are pioneering systems which accumulate hydrogen peroxide (H2O2) from peroxisomal origin during photorespiratory challenges. Respiratory burst oxidase homologues D and F are known to participate in intracellular oxidative stress response launched in cat2 mutants (Chaouch et al., 2012). We studied the compared the transcriptional response of cat2 rbohD and cat2 rbohF double mutants versus the cat2 background to further adress their role during photorespiratory stress. After 3 weeks of growth, leaf tissue from the three different genotypes was harvested in triplicate.

Project description:The combination of robust physiological models with “omics” studies holds promise for the discovery of genes and pathways linked to how organisms deal with drying. Here we used a transcriptomics approach in combination with an in vivo physiological model of re-establishment of desiccation tolerance (DT) in Arabidopsis thaliana seeds. We show that the incubation of desiccation-sensitive (DS) germinated Arabidopsis seeds in a polyethylene glycol (PEG) solution re-induces the mechanisms necessary for expression of DT. Based on a SNP-tile array gene expression profile, our data indicates that the re-establishment of DT, in this system, is related to a programmed reversion from a metabolic active to a quiescent state similar to prior to germination. Our findings show that transcripts of germinated seeds after the PEG treatment are dominated by those encoding LEA, seed storage and dormancy-related proteins. On the other hand, a massive repression of genes belonging to many other classes such as photosynthesis, cell wall modification and energy metabolism occurs in parallel. Furthermore, comparison with a similar system for Medicago truncatula reveals a significant overlap between the two transcriptomes. Such overlap may highlight core mechanisms and key regulators of the trait DT. Taking into account the availability of the many genetic and molecular resources for Arabidopsis, the described system may prove useful for unraveling DT in higher plants.

Project description:Identification of genes differentially expressed in roots of Arabidopsis Col-0 and ndr1-1 mutants 48 h post inoculation with the fungal pathogen Verticillium longisporum. Arabidopsis Col-0 and ndr1-1 seeds were grown in petri dishes with liquid MS medium supplemented with 0.2% sucrose. After two weeks on a horizontal shaker (40 rpm), plants were rinsed twice in sterile distilled water and transferred to liquid 0.5xMS medium without sucrose, supplemented with 200 conidia ml-1 of V. longisporum isolate VL1 (CBS110220). Control plants were grown in 0.5x MS only. At 48 hours post inoculation, materials were harvested in biological replicates (>50 plant roots) and immediately frozen in liquid nitrogen. RNA was extracted with Aurum Total RNA Mini Kit (Bio-Rad) and hybridized to the Arabidopsis ATH1 Genome Array at the DNAVision facility (Gosselies, Belgium). Microarray assays were performed with triplicate biological root samples. Normalization of the microarray data was performed using the Robust Multichip Average (RMA) method as implemented by the “quantile normalization” function in the Bioconductor 1.3 software.

Project description:Comparative transcriptome was profiled of rice seedling shoots in responding to live S. meliloti1021(LS) and dead S. meliloti1021 (DS) inoculation. The shoots with LS and DS were collected at 1, 2, 5 and 8 DAI respectively for microarry analysis. A total of 2413 differentially expressed genes (DEGs) were detected (q ⤠0.05 and 1.5-fold change used as a cutoff), showing significantly differences between LS and DS. Enriched gene ontology terms and pathways analysis indicated that functions of these DEGs were observably involved in biotic stress, cellular regulation, plant hormone transduction, cell cycle and cell division. Among the classes of transcription factors, some key regulatory gene families such as WRKYs, NAC, bZIP, MYB and ZIM were involved in responding to defense. Others such as AUX, E2F/DP, BES1 and GASR were growth related. We used microarrays to profile the global view of gene expression underlying S. meliloti 1021 inoculation and identified regulated plant genes and pathway that likely key events in endophytic colonization and molecular promotion mechanism. Surface sterilized seeds were germinated in petri plates with distilled water in the dark for 3 days at 28°C. And then transferred aseptically into sterilized glass bottle, which containing 175 cm3 of sterile vermiculite and 100 mL of 1/4 Kimura B solution. After 2 days transferred to sterilized glass bottle, the seedling were inoculation with live S. meliloti1021 (LS) as treatment and dead S. meliloti1021 (DS) as control. Shoots from inoculated by live S. meliloti1021 (LS) and dead bacteria as control (DS) were collected at 1, 2, 5 and 8 DAI respectively. Every RNA sample was derived from 5 independent seedlings. In sum, four time points were selected and three biological replicates were performed, totally 24 rice genome arrays were used.

Project description:KMD is genetically engenered to be highly resistant to lepidopteran pests through expressing a synthetic cry1Ab gene and its parent non-transgenic rice is Xiushui 11.The developmental duration of BPH feeding on KMD2 was significantly delayed. And moreover, the fecundity of BPH was significantly lower when fed on Bt rice than on the non-Bt parental plants.To investigate unintended effects in KMD2 that causes changes in BPH performance, we performed microarray (GeneChip) analysis to compare the gene expression profiles between Bt rice and non-transgenic parental plants in response to BPH infestation. We used microarrays to detect Bt-independent variation, which might render Bt rice more defensive or less nutritious to BPH. For BPH treatment, 10 second-instar nymphs were infested onto each 30-day-old seedling. After 72 h, the BPH nymphs were carefully removed and rice shoots of both BPH-infested and non-infested plants were sampled for microarray analysis. There were four treatments: Xiushui 11-non infested, Xiushui 11-BPH infested, KMD2-non infested, KMD2-BPH infested, three biological replications.
