Identification of heat stress-responsive rice microRNAs and their target genes by high-throughput sequencing and degradome analysis

ABSTRACT: In this study, we identified a set of heat stress-responsive miRNAs and verified their targets through degradome sequencing. Nine libraries (triplicate for 0 h, 12 h and 24 h heat treatment) were constructed and sequenced. Four hundred and nineteen conserved miRNAs and 77 novel miRNAs were identified, of which, 40 conserved and two novel miRNAs were expressed differentially. Quantitative PCR of three selected miRNAs and their targets confirmed that these loci were responsive to heat stress. A total of 1364 target transcripts were identified for 114 conserved miRNA and a total of 65 were identified for 22 novel miRNA families. Gene function and pathway analyses showed that these genes probably play vital roles in rice heat stress tolerance.

Identification of miRNAs and their targets in tomato at moderately and acutely elevated temperatures by high-throughput sequencing and degradome analysis

Project description:MicroRNAs (miRNAs) are 19-24 nucleotide (nt) noncoding RNAs that play important roles in abiotic stress responses in plants. High temperatures have been the subject of considerable attention due to their negative effects on plant growth and development. Heat-responsive miRNAs have been identified in some plants. However, there have been no reports on the global identification of miRNAs and their targets in tomato at high temperatures, especially at different elevated temperatures. Here, three small-RNA libraries and three degradome libraries were constructed from the leaves of the heat-tolerant tomato at normal, moderately and acutely elevated temperatures (26/18°C, 33/33°C and 40/40°C, respectively). Following high-throughput sequencing, 662 conserved and 97 novel miRNAs were identified. Of these miRNAs, 96 and 150 miRNAs were responsive to the moderately and acutely elevated temperature, respectively. Following degradome sequencing, 349 sequences were identified as targets of 138 conserved miRNAs, and 13 sequences were identified as targets of eight novel miRNAs. The expression levels of four miRNAs and five target genes obtained by quantitative real-time PCR (qRT-PCR) were largely consistent with the sequencing results. This study enriches the number of heat-responsive miRNAs and lays a foundation for the elucidation of the miRNA-mediated regulatory mechanism in tomatoes at elevated temperatures.

Genome wide identification of circRNAs, miRNAs and their targets in tomatoes at heat, drought and their combination

Project description:Purpose: Circular RNAs (circRNAs) and microRNAs (miRNAs) play important roles in abiotic stress responses in plants. The aims of this study are to genome-widely identify the circRNAs, miRNAs and their targets in tomatoes at single heat, drought and their combination by high-throughput sequencing. Results: Following high-throughput sequencing, 765 miRNAs were identified in total with 335 conserved and 430 novel miRNAs in the 12 small-RNA libraries. Of these miRNAs, 32, 74 and 61 miRNAs were responsive to drought, heat and their combination, respectively. Following degradome sequencing, 50 sequences were identified as targets of 34 miRNAs in tomatoes at combined stress. Moreover, 467 circRNAs were identified in the 12 samples.

MicroRNA-guided regulation of heat stress response in wheat

Project description:Sequencing of 24 small RNA libraries produced 55.2M reads while 404M reads were obtained from the corresponding 24 PARE libraries. From these, 202 miRNAs were ascertained, of which mature miRNA evidence was obtained for 104 and 36 were found to be differentially expressed after heat stress. The PARE analysis identified 589 transcripts targeted by 84 of the ascertained miRNAs. PARE sequencing validated the targets of the conserved members of miRNA156, miR166 and miR393 families as squamosa promoter-binding-like, homeobox leucine-zipper and transport inhibitor responsive proteins, respectively. Heat stress responsive miRNA targeted superoxide dismutases and an array of homeobox leucine-zipper proteins, F-box proteins and protein kinases. Query of miRNA targets to interactome databases revealed a predominant association of stress responses such as signalling, antioxidant activity and ubiquitination to superoxide dismutases, F-box proteins, pentatricopeptide repeat-containing proteins and mitochondrial transcription termination factor-like proteins.

Identification of miRNAs from Glehnia littoralis by high-throughput sequencing and their response to salt stress

Project description:Glehnia littoralis is a perennial herb growing on the sandy beaches. In this study, high-throughput sequencing of small RNA was performed to identify miRNAs and their response to salt stress in G. littoralis. As a result, 37 conserved miRNAs belonging to 13 families and 37 novel miRNAs were identified. Among the 74 miRNAs, the expression levels of miR-156b*, miR-171, miR-171*, and miR-319 were downregulated and that of miR-399a, miR-399a*, miR-399b, miR-399b*, novel-9 and novel-14* were upregulated under salt stress. Target prediction of salt-responsive miRNAs indicated that these miRNAs exerted a role by regulating specific stress-responsive genes, such as SPLs. However, a lot of target genes of salt-responsive miRNAs were uncharacterized, which implied that there might be some new miRNA-mediated reguatory of salt response in G. littoralis. Small RNA profiles of G. littoralis under control (CK), salt stress (SS) and (RS)

Integrated analysis of transcriptome and miRNAome reveals the heat stress response of Pinellia ternata seedlings

Project description:Pinellia ternata (Thunb.) Briet., a valuable herb native to China, is susceptible to the "sprout tumble" phenomenon due to high temperatures, resulting in a significant reduction in yield. The molecular regulatory mechanisms underlying the response of P. ternata to heat stress are not well understood. In this study, we integrated transcriptome and miRNAome sequencing to identify heat response genes, microRNAs (miRNAs), and key miRNA-target pairs in P. ternata under heat stress and room temperature conditions. Transcriptome analysis revealed extensive reprogramming of 4,960 genes across various categories, predominantly associated with cellular and metabolic processes, responses to stimuli, biological regulation, cell parts, organelles, membranes, catalytic and binding activity. miRNAome sequencing identified 1,597 known/conserved miRNAs that were differentially expressed in two test conditions. According to the analysis, genes and miRNAs associated with regulation of transcription, DNA-templated, transcription factor activity and sequence-specific DNA binding pathway, may play a major role in the resistance to heat stress in P. ternata. Integration of expression data of transcriptome and miRNAome determined high confidence 41 miRNA-mRNA pairs forming 25 modules. MYB-like protein and calcium-responsive transcription coactivator may play an integral role in the resistance to heat stress in P. ternata. In addition, the candidate genes and miRNAs were subjected to quantitative real-time PCR to evaluate their expression patterns. These results offer a foundation for future studies exploring the mechanism and critical genes of resistance to heat stress in P. ternata.

Identification of wild soybean miRNAs and their target genes responsive to aluminum stress

Project description:In this study, two small RNA libraries and two degradome libraries were constructed from roots of Al-treated and Al-free Glycine soja seedlings. For miRNA, a total of 7,287,655 and 7,035,914 clean reads in Al-treated and Al-free small RNAs libraries were generated, and 105 known miRNAs ,51 p3/p5 strands of known miRNA and 80 novel miRNAs were identified. Among them, expression of 34 miRNAs was responsive to Al stress. Through degradome sequencing, 82 and 11 genes were identified as tagerts of known and novel miRNAs obtained from this study, respectively. Gene Ontology (GO) annotations of target transcripts indicated that 52 out of 66 targets cleaved by conserved miRNA families may play role in regulation of transcription.
