Rice whole transcriptome differences at two temperature levels surveyed by RNA-Seq

ABSTRACT: We report that TOG1 coordinates global changes of gene expression upon high temperature to support rice thermotolerant growth. We performed gene ontology (GO) enrichment analysis of the differentially expressed genes in rice seedlings grown at 25 ℃ and 30 ℃ and found that when temperature increases, wild-type dramatically adjusts the expression level of hundreds of genes in GO terms polysaccharide metabolic process, carbohydrate metabolic process, glucan metabolic process, carbon fixation, response to stimulus and organic substance metabolic process required for growth. However, in a tog1 mutant, the differentially expressed genes in response to the temperature increase significantly enriched in GO terms response to stimulus, response to oxidative stress and response to stress, whereas the coordination of primary metabolic processes and carbon fixation were largely impaired or undetectable. Differentially expressed mRNA profiles of 22-day-old wild type (WT) and tog1 rice upon a temperature difference were generated by deep sequencing

RNA-Seq dependent transcriptional analysis unveils adaptive mechanisms in the intestine of sea cucumber Apostichopus japonicus during aestivation

Project description:Sea cucumbers (Holothuroidea; Echinodermata), cycle annually between aestivation when water temperature is above about 25°C in the summer and active life when temperature is below about 18°C. We used RNA-Seq to determine gene expression profiles of intestine tissue of A.japonicus during non-aestivation (NA), deep-aestivation (DA), and arousal from aestivation (AA). At least 15 individuals per stage, intestines at NA, DA and AA stages were used for our experiments.

Project description:Sea cucumbers (Holothuroidea; Echinodermata) cycle annually between aestivation, when water temperature is above about 25Â°C in the summer, and active life, when temperature is below about 18Â°C. We used RNA-Seq to determine gene expression profiles of respiratory tree tissue of A. japonicus during non-aestivation (NA), deep-aestivation (DA), and arousal from aestivation (AA). At least 15 individuals per stage, respiratory tree at NA, DA and AA stages were used for our experiments.

Next-generation sequencing analyses of the differently expressed genes of wild type and atcep1 mutant Arabidopsis thaliana

Project description:Purpose: The goal of this study is to compare the differently expressed genes in the wild type and the KDEL-tailed cysteine protease AtCEP1 knockout (atcep1) Arabidopsis using RNA-sequencing (RNA-seq). Methods: Arabidopsis buds mRNA profiles of anther development stages 5-6, 7-9, and 10-11 of the wild type (WT) and atcep1 mutant were generated by deep sequencing via Illumina HiSeqTM 2000. The sequence reads that passed quality filters were analyzed at the transcript isoform level with the following steps: Remove reads with adaptor sequences; Remove reads in which the percentage of unknown bases (N) is greater than 10%; Remove low quality reads, in which the percentage of the low quality base (base with quality value â¤ 5) is greater than 50%. The clean reads were mapped to the Arabidopsis reference genome and reference genes using SOAP aligner/SOAP2. No more than 2 mismatches were allowed in the alignment. The gene expression level was calculated using RPKM (Reads Per Kb per Million reads). Differential expression analysis between the wild type and the atcep1 mutant was performed using the DEGseq R package (1.12.0) based on normalized read counts. A corrected P value of < 0.005 and |log2Ratio| > 1 were set as the threshold for significantly differential expression. Results: We identified 872 genes showing significant differential expression, and in the atcep1 mutant, the upregulated genes significantly outnumbered the downregulated genes at the three time points. The GO analysis of the differently expressed genes showed that the expression of genes participating in anther tapetal secretory structure formation, pollen wall development, and tapetal cell wall generation, clearly changed. Arabidopsis buds mRNA profiles of development stages 5-6, 7-9, and 10-11 of the wild type (WT) and atcep1 muant were generated by deep sequencing via Illumina HiSeqTM 2000.

A global profiling of gene expression in chilling stress in rice

Project description:RNA-Seq was performed to study the change of gene expression before and after chilling treatment in rice. Different change patterns were identified. We have provided a complete view of transcriptome under cold stress condition, which will deepen our understanding of gene expression regulation in cold stress response as well as cold stress response mechanism for monocot plants. The mRNA profiles of 15-day-old rice seedlings with and without chilling treatment (4 Â°C for 33 h) were generated by deep sequencing using Illumina Hiseq 2000 platform.

12DAA 20DAA 28DAA RNA-Seq

Project description:According to the physiological change of the ear leaf, the developing ear leaf after pollination can be divided into three classes: mature leaves [ML, 0–14 days after pollination (DAP)]; early senescent leaves (ESL, 15–24 DAP); and later senescent leaves (LSL, 25–30 DAP). We harvested ear leaves at 12 DAP, 20 DAP, and 28 DAP, representing ML, ESL, and LSL, respectively. To identify genes involved in the leaf senescence process, we sequenced three cDNA libraries, ML (12 DAP), ESL (20 DAP), and LSL (28 DAP) using an Illumina HiSeqTM 2000.

Transcriptomic analysis of wild-type (WT) and curled-cotyledon(cco) mutant in soybean

Project description:Soybean is one of the most economically important crops in the world. The cotyledon is the nutrient storage area in seeds, and it is critical for seed quality and yield. Cotyledon mutants are important for the genetic dissection of embryo patterning and seed development.Here, we characterised a soybean curled-cotyledon (cco) mutant. Compared with wild-type (WT), the entire embryos of cco mutant resembled the “tail of swallow”. To explore the molecular mechanisms underlying soybean cotyledon development, we executed RNA-Seq using the Illumina HiSeq2000 system. Pods at 7DAF collected from WT and cco were analyzed by RNA-seq.

RNA-seq transcriptome analysis of Panax japonicus, and its comparison with other Panax species to identify potential genes involved in the saponins biosynthesis

Project description:In this study, we have performed Illumina based RNA sequencing to characterize the transcriptome and expression profiles of genes expressed in 5 tissues of P. japonicus. RNA sequencing and de novo transcriptome assembly for P. japonicus resulted in a total of 135,235 unigenes with 78,794 (58.24%) unigenes being annotated using NCBI-nr database. Transcriptome profile and GO enrichment analysis for 5 tissues of P. japonicus showed that although each tissue was characterized by several unique unigenes with leaf showing the most unique unigenes among all, overall processes were evenly conserved across all tissues. Examination of 5 tissues of Panax japonicus

RNA-seq of pericarp of purple-grain wheat Luozhen No.1 of 15 days (D15) and 20 days (D20) shading treatment after pollination, against 15 DAP, 20 DAP untreated controls. The purple-grain wheat were grown under natural field conditions at Shandong Agricultural University Experimental Station (36169 N, 117169 E), Taian, China during Octubor, 2015 to June, 2016.

Project description:Purple-grain wheat are caused by anthocyanin accumulation in the seed coat. But little is known about molecular mechanism of anthocyanin biosynthesis. The anthocyanin biosynthesis and accumulation were affected by light in purple-grain wheat. The spikes of purple-grain wheat Luozhen No.1 were bagged with four-layer Kraft paper bags after pollination. To identify genes involved in the anthocyanin biosynthesis, we sequenced four pericarp cDNA libraries, D15 (15 DAP), D20 (20 DAP) of shading treatment, and L15 (15 DAP), L20 (20 DAP) of untreated control using an Illumina HiSeqTM 2000. After quality control, raw reads are filtered into clean reads which will be aligned to the reference sequences. The alignment data is utilized to calculate distribution of reads on reference genes and mapping ratio, and proceed with downstream analysis including gene and isoform expression, deep analysis based on gene expression (PCA/correlation/screening differentially expressed genes and so on),exon expression, gene structure refinement, alternative splicing, novel transcript prediction and annotation, SNP detection, Indel detection. Further, we also perform deep analysis based on different expression genes, including Gene Ontology (GO) enrichment analysis, Pathway enrichment analysis, cluster analysis, and finding transcriptor factor.
