Project description:Purpose: To identify abiotic stress responsive and tissue specific miRNAs at genome wide level in wheat (Triticum aestivum) Results: Small RNA libraries were constructed from four tissues (root, shoot, mature leaf and spikelets) and three stress treatments of wheat seedlings (control, high temperature, salinity and water-deficit). A total of 59.5 million reads were obtained by high throughput sequencing of eight wheat libraries, of which 32.5 million reads were found to be unique. Using UEA sRNA workbench we identified 47 conserved miRNAs belonging to 20 families, 1030 candidate novel and 51 true novel miRNAs. Several of these miRNAs displayed tissue specific expression whereas few were found to be responsive to abiotic stress treatments. Target genes were predicted for miRNAs identified in this study and their grouping into functional categories revealed that the putative targets were involved in diverse biological processes. RLM-RACE of predicted targets of three conserved miRNAs (miR156, miR160 and miR164) confirmed their mRNA cleavage, thus indicating their regulation at post-transcriptional level by corresponding miRNAs. Expression profiling of confirmed target genes of these miRNAs was also performed. Conclusions: This is the first comprehensive study on profiling of miRNAs in a variety of tissues and in response to several abiotic stresses in wheat. Our findings provide valuable resource for better understanding on the role of miRNAs in stress tolerance as well as plant development. Additionally, this information could be utilized for designing wheat plants for enhanced abiotic stress tolerance and higher productivity. Total eight (three stress, one control and four tissue specific small RNA libraries were pepared and sequenced independently [wheat control (WC), wheat high temperature stressed (WHTS), wheat salinity stressed (WSS) and wheat drought stressed (WDS), wheat shoot(WSH), wheat leaf (WLF), wheat flower(WFL), wheat root(WRT)] on Illumina GAIIx

Project description:We report the application of transcriptome sequencing technology for high-throughput profiling of Serratia marcescens for producing prodigiosin. By obtaining over 163 million bases of sequence from Serratia marcescens genome DNA, we generated transcriptome -state maps of Serratia marcescens 12h cells, 24h cells, and 36h cells at 30C and 37C,respectively. We explored the mechanism of S. marcescens response temperature regulation at the transcription level through transcriptome sequencing technology. We found that the pig gene cluster at low temperature would favor at the transcriptional level, however, higher temperature resulting in instability and loss of enzyme activity. Numerous amino acid metabolic pathways involved in prodigiosin biosynthesis in S. marcescens responded to temperature changes, and metabolic fluxes were directed towards prodigiosin biosynthesis. At the same time, quorum sensing, two-component regulatory system and sRNA were stimulated by temperature to regulate PG biosynthesis and involve strain virulence and exclusive genes. Moreover, inhibition factors was the one reason for S. marcescens incapable synthesis of prodigiosin at 37C. This study laid a good foundation for understanding the biological functions of prodigiosin, improving the temperature tolerance of industrial strains, and excavating temperature-sensitive regulatory elements.

Project description:Exposure to cold conditions is a major abiotic stress affecting crop growth and productivity. Elucidation of genetic mechanisms underlying response to low temperature is needed. To assess the relationship between the genes and the cold tolerance of wheat, transcriptomics analyses were performed to study changes in gene profiles of cultivar Jing 411 after cold acclimation and freezing treatment. The wheat cultivar Jing 411 was subjected to transcriptome sequencing. The RNA was sequenced on a HiSeq 2500 platform, and the generated data were analyzed using TopHat v2.0.

Project description:Purpose: We aimed to provide a basis for the adaptive mechanism and a rich resource for the discovery and identification of novel genes involved in the cold and heat stress response in Solenopsis invicta. retinal transcriptome profiling (RNA-seq) to microarray and quantitative reverse transcription polymerase chain reaction (qRT–PCR) methods and to evaluate protocols for optimal high-throughput data analysis Methods: Solenopsis invicta was reared at lab condition, and incubated at 4 different temperature for 24h (10, 20, 30 and 40℃). RNA was extracted using Trizol reagent and Illumina sequencing was performed at Macrogen. Illumina short reads were quality-filtered and Illumina-based de novo transcriptome assembly was performed. Differential Gene Expression Analysis was studied for different tempearture conditions. Results: Totally 99,085 unigenes was obtained which at least 19,154 were annotated with gene descriptions, gene ontology terms, and metabolic pathways. 86 GO functional sub-groups and 23 EggNOG terms resulted. DEGs with log2FC≥10 were screened and were compared at different temperatures. We found 203, 48 and 66 specific DEGs co-regulated at 10, 20 and 40℃, respectively compare with 30℃. Comparing transcriptome profiles for differential gene expression resulted various DE proteins and genes, including cytochrome P450, NADH dehydrogenase subunit 1, cuticle protein and HSP which have previously been reported to be involved in cold and high temperature resistance. GO analysis revealed that antioxidant activity up-regulated under high temperature stress. Conclusions: we compared the transcriptomes of S. invicta under high- and low-temperature stresses using RNA-Seq technology based on the high-throughput sequencing. Comparative transcriptome analysis identified many genes and a large number of changes were discovered in metabolic pathway through the GO and KEGG enrichment analysis. Our data will facilitate further molecular investigations and genomic research. Many high- and low-temperature significantly up-regulated genes were first identified in this study. These newly found genes may be important and necessary to RIFA overwintering and its behavior for adaptation in new environment as well as quarantine area.

Retinal transcriptome profiling (RNA-seq) to microarray and quantitative reverse transcription polymerase chain reaction (qRT–PCR) methods and to evaluate protocols for optimal high-throughput data analysis Methods: Solenopsis japonica was reared at lab condition, and incubated at 2 different temperature for 24h (9, and 25℃) under dark conditions. RNA was extracted using Trizol reagent and Illumina sequencing was performed at Macrogen. Illumina short reads were quality-filtered and Illumina-based de novo transcriptome assembly was performed. Differential Gene Expression Analysis was studied for different tempearture conditions. Results: Totally 89,657 unigenes was obtained which overall 43,375 were annotated with gene descriptions, gene ontology terms, and metabolic pathways. 86 GO functional sub-groups and 25 EggNOG terms resulted. DEGs with FC≥2 and FC≤-2, P-value<0.05 were screened and were compared at two different temperatures. We found 138 DEG down regulated and 271 DEG up regulated when the S. japonica incubated at 9 ℃ and compared with 25℃ treated group. Comparing transcriptome profiles for differential gene expression resulted various DE proteins and genes, including cytochrome P450, NADH dehydrogenase subunit 1, cuticle protein and HSP which have previously been reported to be involved in cold and high temperature resistance. GO analysis revealed that antioxidant activity up-regulated under high temperature stress. Conclusions: we compared the transcriptomes of S. japonica under normal room temperature and low-temperature using RNA-Seq technology based on the high-throughput sequencing. Comparative transcriptome analysis identified many genes and a large number of changes were discovered in metabolic pathway through the GO and KEGG enrichment analysis. Our data will facilitate further molecular investigations and genomic research. Many low-temperature significantly up-regulated genes were first identified in this study. These newly found genes may be important and necessary to S. japonica overwintering and its behavior for adaptation in new environment.
