Identification of CLF-regulated transcripts using strand-specific RNA-sequencing in Arabidopsis

ABSTRACT: CURLY LEAF (CLF), the major histone methyltransferase of Polycomb Repressive Complex 2 (PRC2), modifies trimethylation of histone H3 lysine 27 (H3K27me3) and mediates dynamical chromatin repression in Arabidopsis. Here we used strand specific RNA-sequencing to profile Arabidopsis transcriptomes obtained from roots, shoots, flowers and siliques of Col-0 and clf-28 plants. Our analysis identified a large number of CLF-regulatedd transcripts in Arabidopsis. Transcriptome profiling in roots, shoots, inflorescences and siliques of WT and clf-28 plants with 3 biological replicates.

CURLY LEAF (CLF), a histone methyltransferase of Polycomb Repressive Complex 2 (PRC2) for trimethylation of histone H3 Lys 27 (H3K27me3), has been thought as a negative regulator controlling mainly postgermination growth in Arabidopsis (Arabidopsis thaliana). Approximately 14% to 29% of genic regions are decorated by H3K27me3 in the Arabidopsis genome; however, transcriptional repression activities of PRC2 on a majority of these regions remain unclear. Here, by analysis of transcriptome profiles ...[more]

Project description:CURLY LEAF (CLF), the major histone methyltransferase of Polycomb Repressive Complex 2 (PRC2), modifies trimethylation of histone H3 lysine 27 (H3K27me3) and mediates dynamical chromatin repression in Arabidopsis. Here we profiled Arabidopsis transcriptomes obtained from roots, leaves, flowers and siliques of Col-0 (As described under GEO ID: GSE38612) and clf-28 plants using RNA-seq. Our analysis uncovered 3835 transcription units were up-regulated in clf-28. Compared with ChIP-CHIP data, we found at least 42% of them were associated with H3K27me3. Transcriptom profiling in roots, leaves, flowers and siliques of clf-28 plants.

Identification of CLF-regulated transcripts in embryos at the mature-green stage by strand-specific RNA-sequencing in Arabidopsis

Project description:CURLY LEAF (CLF), the major histone methyltransferase of Polycomb Repressive Complex 2 (PRC2), modifies trimethylation of histone H3 lysine 27 (H3K27me3) and mediates dynamical chromatin repression in Arabidopsis. Our previous results suggested that CLF may play regulatory roles on seed size and lipid biosynthesis in embryos at the mature-green stages. Here we used strand specific RNA-sequencing to profile Arabidopsis transcriptomes obtained from isolated embryos at the mature-green stage of Col-0 and clf-28 plants. Our analysis identified a large number of CLF-regulatedd transcripts in developmenting embryos in Arabidopsis. Issolated embryos of WT and clf-28 with 2 biological replicates

Transcriptome profiling of siliques at 4 developmental stages in Arabidopsis

Project description:To search for the differential expressed genes during post-fertilization and embryonic development in Arabidopsis, We profiled transcriptome of siliques at 4 developmental stages using RNA-seq based on poly(A) selection. Each RNA library yielded 100 million 101-bp paired-end reads.Using Tophat and Cufflinks with the Arabidopsis TAIR10 annotation as reference, we identified 33,451 assembled transcripts in 4 samples. Of them, 5,608 were up-regulated genes in at least one sample. A group of them are preferentially expressed at mature green-stage of seeds. Transcriptome profiling in 0-5 day, 6-10 day, 11-15 day and 16-20 day post-anthesis siliques

Identification of long ncRNAs using RNA-seq in Arabidopsis

Project description:We profiled Arabidopsis transcriptom using RNA-seq. Each RNA library yielded 223-250 million 101-bp single-end reads (235M on average). Using Tophat and Cufflinks, 30,199~30,650 assembled transcripts were identified in each of 4 samples. Of them, 1340 ones were derived from intergenic regions including 278 long intergenic ncRNAs (LincRNAs). Comparing with the 6,480 lincRNAs we identified by analysis of 200 tiling array data sets, 2,708 lincRNAs were also detected by RNA-seq. Transcriptom profiling in roots, leaves, flowers and siliques.

Analysis of gene expression patterns of Arabidopsis roots grown in methyl jasmonate (MeJA), cytokinin (CK), MeJA/CK- treated conditions

Project description:Purpose: Understanding of MeJA, CK effect on regulation of gene expression patterns in Arabidopsis roots Total mRNA was extracted from 7-day-old Arabidopsis roots grown in MeJA (10uM), CK (50nM) and MeJA/CK-treated conditions. To generate cDNA libraries with TruSeq RNA library kit, 1 Î¼g of total RNA was used. This step consisted of polyA-selected RNA extraction, RNA fragmentation, random hexamer primed reverse transcription and 100 nt paired-end sequencing by Illumina HiSeq2000. 4,403 genes satisfying |fold change|â¥2 in at least one data set were collected.
