Identification of microRNAs and Their Targets in Ulmus pumila under Salt Stress by High-Throughput Sequencing

ABSTRACT: MicroRNAs (miRNAs) are a class of endogenous small RNAs that play important roles in growth, development, and environmental stress response processes in plants. Ulmus pumila is a typical deciduous broadleaved tree species of north temperate, and is widely distributed in central and northern Asia, which has important economic and ecological value. With the spread and aggravate of soil salinisation, salt stress has become a major abiotic stress that highly affects the normal growth and development of U. pumila. However, to date, no investigation into the influence of salt stress on U. pumila miRNAs has been reported. To identify miRNAs and predict their target mRNA genes under salt stress, three small RNA libraries were generated and sequenced from CK (without salt stress), LSS (light salt stress for a short time) and MSL (medium-heavy salt stress for a long time) roots of U. pumila seedlings. Through integrative analysis, 245 conserved miRNAs representing 30 families and 64 novel miRNAs were identified, of which 89 exhibited altered expression level under salt stress, and 232 potential targets for the miRNAs were predicted and annotated in U. pumila. The expressions of six differentially expressed miRNAs were validated by qRT-PCR. These salt responsive miRNAs may play crucial roles in U. pumila defense against salt stress, and our miRNA data provides valuable information regarding further functional analysis of miRNAs involved in salt tolerance of U. pumila and other forest tree species.

Identification of known and novel miRNAs in the salt tolerant rice Oryza sativa cv. Pokkali in root and shoots of control and NaCl exposed seedlings

Project description:The advent of next generation sequencing (NGS) has greatly enriched the database of miRNAs. For plants so far 8455 miRNAs sequences from 73 species and 15401 miRNAs sequences from 150 species have been deposited in miRBase 21.0 and Plant Non-coding RNA Database, respectively. The occurrence of miRNAs in such a huge number, which is still increasing, is because of the fact that the profile of miRNAs expression differs greatly from species to species, both quantitatively and qualitatively. Besides, even within a species it is expected that the miRNA expression profile would differ from cultivar to cultivar depending on the trait with regard to which the two cultivars differ, and on the same logic it is also expected that their expression profile would differ considerably in the plant under contrasting environmental conditions. However, report on comparative study of expression profile of miRNAs in rice cultivars, or in any crop cultivars, contrast for salt tolerance, or tolerance to any abiotic stress is scant. Therefore, the current study was planned to see the expression profile of miRNAs in a salt-tolerant rice (Oryza sativa L. ssp indica) cultivar (cv.) Pokkali in presence and absence of NaCl and to check the response pattern of a few important salt-responsive miRNAs in a salt-sensitive rice cultivar Badami in order to identify the miRNAs and their targets that could be involved in the salt tolerance process

RNA-seq Analysis of the Salt Stress Induced Transcripts in Fast Growing Bioenergy Tree, Paulownia elongata

Project description:Paulownia elongata is a fast-growing tree species native to China that is grown in different climates, types of soils, and can be easily re-grown. The versatility of the P. elongata species makes it an ideal candidate for biofuel production. High soil salinity is known to inhibit plant growth dramatically or lead to death. Salinity in soil is a detrimental abiotic stress affecting crop production worldwide and a hindrance for potential crop candidates used for biofuel production. The purpose of this study was to characterize the salt-induced transcriptome of P. elongata. Transcriptome differences in response to salt stress were determined by RNA sequencing (RNA-seq) using next generation sequencing and bioinformatics analysis. A total of 646 genes were found to have significant altered expression in response to salt stress, and expression levels of a selective subset of these genes were chosen and confirmed using quantitative real-time PCR. To the best of our knowledge, this is the first report of salt-induced transcriptome analysis in P. elongata. The current study indicates that the differential expression of certain genes may have an important role in the adaptation of P. elongata in response to salt stress. Functional characterization of these genes will assist in future development of salt tolerance in P. elongata, which could be used to enhance biofuel production.

Identification of microRNAs in Caragana intermedia by high-throughput sequencing and expression analysis of 12 microRNAs and their targets under salt stress

Project description:MicroRNAs (miRNAs) are endogenous small RNAs that play important roles in various biological and metabolic processes in plants. Caragana intermedia is an important ecological and economic tree species that is prominent in the desert environment of west and northwest China. To date, no investigation into C. intermedia miRNAs has been reported. In this study, high-throughput sequencing of small RNAs was performed to identify both conserved and novel miRNAs, and also their target mRNA genes in C. intermedia. Based on sequence similarity and hairpin structure prediction, 132 putative conserved miRNAs (12 of which were confirmed to form hairpin precursors) belonging to 31 known miRNA families were identified. Ten novel miRNAs (including the miRNA* sequences of three novel miRNAs) were also discovered. The expression of 12 miRNAs was validated in different tissues, and the 12 miRNAs were further assessed by qRT-PCR after salt treatment. Furthermore, 36 potential target genes of 17 known miRNA families and two potential target genes of one novel miRNA were predicted, and some target genes were also assessed by qRT-PCR after salt treatment. Our study provides a basic catalog of miRNAs and their targets, which will promote further understanding of the important roles of miRNAs in C. intermedia and in other species of the leguminous genus, Caragana.

Olive (Olea europaea) cv.Chondrolia Chalkidikis: Control vs NaCl-treated

Project description:A comparative transcriptomics approach was used as a tool to unravel gene regulatory networks underlying salinity response in olive trees by simulating as much as possible olive growing conditions in the field. Specifically, we investigated the genotype-dependent differences in the transcriptome response of two olive cultivars, a salt tolerant and a salt sensitive. A 135 day long comparative salinity experiment was conducted using one year old trees exposed to NaCl stress for 90 days followed by 45 days of post-stress period. Total RNA was extracted from the root samples after 15, 45 and 90 days of NaCl-treated and un-treated olive trees as well as after 15 and 45 days of post-treatment period and used for microarray hybridizations using a loop design. Hierarchical clustering of differentially expressed transcripts revealed two major, distinct clusters for each cultivar. Despite the limited number of probe set, transcriptional regulatory networks were constructed for the salt-tolerant and salt-sensitive cultivar. The comparison of the salt responsive transcriptional regulatory networks in olive with those reported for Arabidopsis suggests that a tree species might respond in a similar to Arabidopsis way at the transcriptome level under salinity stress.

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.
