Expression data from rice seedlings of wild type and the CHR729 mutant

ABSTRACT: In order to study the function of CHR729 in rice, the T-DNA insertion mutant of CHR729 was obtained and analysed. Total RNAs were extracted from 11-day-old seedlings of both wild type (Hwayoung) and CHR729 mutant plants. Affymetrix GeneChip® Rice Genome Array hybridization was performed with three biological replicates. Data was analyzed with SAM Excel add-in and in-house perl scripts. Results showed that 254 genes are up-regulated, and 345 genes are down-regulated (with q – value at 5%).

CHD3 protein recognizes and regulates methylated histone H3 lysines 4 and 27 over a subset of targets in the rice genome.

Histone lysine methylation is an important component of the epigenetic system demarcating transcriptionally active and inactive chromatin domains. It is of primary importance in understanding how different histone lysine methylation marks and a specific combination of them are read and interpreted by chromatin proteins to regulate gene expression. In this paper, we report that the rice CHD3 protein CHR729 that was required for many aspects of plant development can interact with dimethylated hist ...[more]

Down-regulation of OsSRT1 induces DNA fragmentation and cell death in rice

Project description:In order to study the physiological function of OsSRT1, a 412 bp segment of the 3’-untranslated region of OsSRT1, which was not conserved with OsSRT2, was inserted in inverted repeats to build a construct for RNA interference (RNAi). The construct was used to transform an indica rice variety (Minghui63).To study whether the down-regulation of OsSRT1 affected gene expression, we compared the transcripts of the RNAi to the wild type plants by microarray analysis (Affymetrix). RNAs were isolated from young leaves of 11 day-old plants (before appearance of lesions in the RNAi plants). Affymetrix GeneChip® Rice Genome Array were performed. Data was analyzed with SAM excel add-in and in-house perl scripts.Analysis of data from three biological repeats revealed that 521 genes are up-regulated, and 213 genes are down-regulated (with q – value at 5%).

Differential microRNA expression and microRNA editing upon HP-PRRSV infection in vivo across different pig breeds

Project description:Purpose: To characterize the differential microRNA expression profiles and microRNA editing upon PRRSV infection, using NGS techonology, we sequenced small RNAs of the lungs of Tongcheng and Landrace pigs before (0 dpi) and after (3, 5, 7 dpi) infection with high-pathogenic PRRSV (HP-PRRSV). Methods: The miRNA expression profiles of the lungs of Tongcheng and Landrace pigs before (0 dpi) and after (3, 5, 7 dpi) HP-PRRSV infection were produced by using solexa platform. The raw reads with low qualities were filtered and the clean high quality reads were mapped to Ensembl Sus reference genome 10.2.71 using BWA. The unique mapped reads were retained for microRNA expression analysis. The raw reads counts of each microRNA were calculated by perl scripts and the differentially expressed microRNA (Fold change >2; FDR <0.05) were called using edgeR. The microRNA editing was identified using the methods described by Alon, S. and E. Eisenberg. Methods Mol Biol, 2013. Further analysis of microRNA editing was performed with perl scripts.

Expression data from rice lesion mimic mutant spotted leaf 5 (spl5)

Project description:The rice lesion mimic, spotted leaf 5 (spl5), created by M-NM-3-ray radiation, has spontaneous HR-like lesions on its leaves and shows enhanced resistance to rice blast and bacterial blight pathogens. Some genes were differentially expressed in this mutant compared with its WT control ZF802, and these genes were also associated with some important signaling pathways, such as defense response, oxidation-reduction process and stress response. We analyzed the transcriptional profiling of spl5 mutant and WT using the microarray, in order to reveal the signal pathway of SPL5 gene in regulation of disease resistance. Rice leaves were selected at lesion stages of spl5 mutant for RNA extraction and hybridization on Affymetrix microarrays. The lesions in rice leaves were belong to HR phenotype, which was one of the important reasons for rice disease resistance. In order to realize which genes were associated with the degree of lesions and mediated the disease resistance, we put the leaves of spl5 mutant into two categories, based on the degree of lesion formation: few lesions (FL), leaf area with 10-20% lesions and many lesions (ML), leaf area with 70-80% lesions.

RNA Sequencing analysis of transcriptomics to investigate the bile stress response in L. paracasei L9

Project description:Purpose: To understand the bile salts resistance mechanisms in L. paracasei L9 Methods: Samples from L9 cultured with or without bile salts were sequenced on an Illumina Hiseq platform. Three independent biological replicates were produced including 6 samples in total. Results: Raw data were firstly processed through in-house perl scripts to generate clean data, and then clean date were mapped to the reference genome, getting about 8-10 million total mapped reads per sample.

Babesia Infected/Control LongSAGE libraries for Boophilus microplus ovary tissue

Project description:Babesia infected (and control) ovary tissue was used to construct LongSAGE libraries. The intent was to find differential gene expression in both libraries. Details: The extraction was done using Ambion's ToTALLY RNA kit, and the concatemers where constructed using Invitrogen's I-SAGE Long kit. The concatmer files (multiple fasta sequence files) were processed using in-house perl scripts to extract the 17bp LongSAGE tags. **Note: contact person: Felix D.

Identification of rice ethylene-response mutants and characterization of MHZ7 in distinct ethylene response and yield trait regulation

Project description:Ethylene plays major roles in adaptive growth of rice plants in water-saturated soil; however, ethylene signaling in rice is largely unclear. Here, we report identification and characterization of ethylene-response mutants based on distinct ethylene-response phenotypes of dark-grown rice seedlings. The seeds were soaked in tap-water and germinated at 37M-BM-0C in the dark for two days (change the water daily). For ethylene treatment, we reduced the amount of water to 1.5-1.7cm below the seeds.Three-day old seedlings were treated with ethylene (10 ppm) for 8 hours at 28M-BM-0C in the dark. Seedling grown in the air was used as control. We isolated RNA from roots and shoots of wild-type and mutant.

Project description:In this dataset, we include the expression data obtained from untreated and blast pathogen treated rice seedlings using a variety of blast resistant rice line H4, as well as the susceptible rice line Zhonger-Ruanzhan. These data are used to obtain 4087 genes that are differentially expressed in response to blast pathogen in both of rice lines,as well as 717 genes that are differentially expressed between different lines both in the moch-treated and the blast treated. We used microarrays to detail the global gene expression in leaf from blast resistant rice line and susceptible rice line Four total samples were analyzed, The untreated rice line Zhonger-Ruanzhan: Zhonger-0;the untreated rice line H4:H4-0;Zhonger-Ruanzhan inoclutated with blast pathogen after 24h:Zhonger-24;H4 inoculated with blast pathogen after 24h: H4-24. We generated the following pairwise comparisons : H4-0 VS H4-24; Zhonger-0 vs Zhonger-24; H4-0 vs H4-0; Zhonger-24 vs H4-24.

GATA Transcription Factor (CGA1) Regulates Chloroplast Development in Rice

Project description:A transcription factor CYTOKININ-RESPONSIVE GATA FACTOR 1 (CGA1) regulates chloroplast development in rice (Oryza sativa) through modifying the expression of important nuclear expressed, chloroplast localized genes. A transcriptome analysis was done in wild type plants and transgenic rice over-expressing this OsCGA1 to identify the set of genes with altered expression. RNA was extracted from leaves of 4-wk old wild type and OsCGA1 overexpressing rice plants and hybridized to Affymetrix Rice Genome Array. Three biological replicates were sampled for wild type and OX plants.
