Identification of microRNAs that are differentially expressed in drought and As stressed rice

ABSTRACT: We have characterized the changes in miRNA expression profiles in rice leaves under drought stress and As stress and compared these to unstressed leaves. 10 pairs of drought responsive and 8 pairs of As responsive miRNA-gene were identified and validated by qRT-PCR. This study identifies putative specific miRNA-mRNA regulatory modules with roles during drought and As stress. Putative microRNAs identified in this study are involved in hormone signaling, lipid and carbohydrate metabolism, and antioxidant defence. The results of this study will assist in elucidating the role of miRNAs in post-transcriptional regulation of target genes during abiotic stress and may contribute to the development of strategies to engineer drought and heavy metal resistance.

Gene expression profile from field-grown drought-stressed cotton

Project description:Drought-responsive genes were identified in leaf tissues of the cotton Acala 15-1799, a cotton genotype derived in the Southwest USA. Most of the identified genes such as the heat shock proteins have been described as responsive to drought and heat in other plant species. Microarray analysis was used to identify drought-responsive genes that might confer this cotton genotype with an improved tolerance to drought stress. Leaves from cotton plants watered or exposed to drought stress were used for RNA extraction and generarion of cRNA probes for hybridization of Affymetrix microarrays. Microarray technology was used to identify drought-responsive genes in cotton to assist in molecular breeding program. The supplementary file 'GSE18253_differentially_expressed.txt' lists the differentially expressed genes.

Differential gene expression analysis of drought responsive sense and antisense genes in Populus

Project description:In this study we employ a strand-specific RNA-seq appoach and stranded gene expression analysis tools to identify drought responsive antisense gene loci and sense-antisense gene pairs in Populus. we generated and sequenced 28 strand-specific cDNA libraries derived from either leaf or root tissues of Populus trichocarpa plants associaed with both short-term drought (24 hours of water stress of 40% of field capacity) and long-term drought ( 25 days of water stress of 40% of field capacity) . We mapped over 71 billion nucleotides to Populus genome. Our data demonstrates that with the current sequence depth ~ 19 % of Populus genome undergoes antisense transcription subjected to drought regulation. All in all we have identified that in root tissues 524 differentially expressed antisense genes and 247 drought-responsive SA gene pairs which are significantly regulated by drought (padj <0.05). Taken all data from both drought treatments, we have identified 1185 unique drought-responsive antisense gene loci and 606 drought-responsive SA gene pairs (padj <0.05).

A Genome-Wide Characterization of New and Drought Stress Responsive MicroRNAs in Populus euphratica

Project description:We present an efficient method to genome-wide discover new and drought stress responsive miRNAs in P. euphratica. High throughput sequencing of P. euphratica leaves found 197 conserved miRNAs between P. euphratica and Populus trichocarpa. Meanwhile, 189 new miRNAs which belonged to 120 families were identified, a large increasing to the number of P. euphratica miRNAs. Target prediction and degradome sequencing verification of 22 new and 21 conserved miRNA targets showed these targets were involved in multiple biological processes, including transcription regulation and response to stimulus. Furthermore, comparison of high-throughput sequencing with miRNA microarray profiling data indicated that 104 miRNA sequences were up-regulated, while 27 were down-regulated under drought stress. This preliminary characterization based on our findings provided a framework for future analysis of miRNA genes and their roles in key traits of poplar as stress resistance plant breeding and environment protection usage. Examination of sRNA expression in 2 poplar leaf samples in drought and normal growth conditions.

Identification and characterization of novel maize miRNAs involved in different genetic background

Project description:MicroRNAs (miRNAs) are a class of small, non-coding regulatory RNAs that regulate gene expression by guiding target mRNA cleavage or translational inhibition in plants and animals. At present there is relatively little information regarding the role of miRNAs in the response to drought stress in maize. In this study, two small RNA libraries were sequenced, and a total of 11,973,711 and 14,326,010 raw sequences were generated from growing leaves of drought-tolerant and drought-sensitive maize seedlings, respectively. Further analysis identified 192 mature miRNAs, which include 124 known maize (zma) miRNAs and 68 potential novel miRNA candidates. Additionally, 167 target genes (259 transcripts) of known and novel miRNAs were predicted to be differentially expressed between two maize inbred lines. Of these, three novel miRNAs were up-regulated and two were down-regulated under drought stress. The expression of these five miRNAs and nine target genes was confirmed using quantitative reverse transcription PCR. The expression of three of the miRNAs and their putative target genes exhibited an inverse correlation, and expression analysis suggested that all five may play important roles in maize leaves. Finally, GO annotations of the target genes indicated a potential role in photosynthesis, may therefore contribute to the drought stress response. This study describes the identification and characterization of novel miRNAs that are the differentially expressed in drought-tolerant and drought-sensitive inbred maize lines. This provides the foundation for further investigation into the mechanism of miRNA function in response to drought stress in maize.

Utilization of transcriptome, small RNA, and degradome sequencing to provide insights into drought stress and re-watering treatment in Medicago ruthenica (Degradome-Seq)

Project description:Drought is a major limiting factor in foraging grass yield and quality. Medicago ruthenica is a high-quality forage legume with drought resistance, cold tolerance, and strong adaptability. In this study, we integrated transcriptome, small RNA, and degradome sequencing in identifying drought response genes, miRNAs, and key miRNA-target pairs in M. ruthenica under drought and re-watering treatment conditions. A total of 3,905 genes and 50 miRNAs (45 conserved and 5 novel miRNAs) were significantly differentially expressed between the re-watering (RW) vs. drought (DS) comparison and control (CK) groups. The degradome sequencing analysis revealed that 348 miRNAs (37 novel and 311 conserved miRNAs) were identified with 6,912 target transcripts, forming 11,390 miRNA-target pairs in the three libraries. There were 38 differentially expressed targets from 16 miRNAs in DS vs. CK, 31 from 11 miRNAs in DS vs. RW, and 6 from 3 miRNAs in RW vs. CK; 21,18, and 3 miRNA-target gene pairs showed reverse expression patterns in DS vs. CK, DS vs. RW, and RW vs. CK comparison groups, respectively. These findings provide valuable information for further functional characterization of genes and miRNAs in response to abiotic stress, in general, and drought stress in M. ruthenica, and potentially contribute to drought resistance breeding of forage in the future.

Transcription profiling of Arabidopsis wild type and abi1td mutant plants stressed by ozone or drought to better understand ABA signalling

Project description:Ozone at an elevated level is an important environmental stress factor that limits plant growth and development. To test how O3-induced ROS signalling interacts with the ABA pathway we present a global characterization of O3-responsive genes in the abi1td mutant. To understand better ABA signalling and the interactions between stress-response pathways we also performed a microarray analysis of drought-treated abi1td and WT plants. Since ABA signalling is well known to mediate defined responses based on the WT and different mutants analysis in drought stress conditions, the comparison of the O3 and drought stress response in abi1td enabled the identification of new processes depending on ABA-related pathways in O3-treated plants. Altogether, our findings indicate that ABI1 plays the role of a general signal transducer linking diferrent hormone signalling pathways to O3 stress tolerance.<br><br><br><br>Key words: ROS signalling; ABA signalling; ozone stress; drought stress; environmental stress; gene knockout;
