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

ABSTRACT: 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.

Project description:Salt stress is a primary cause of crop losses worldwide, and it has been the subject of intense investigation to unravel the complex mechanisms responsible for salinity tolerance. MicroRNA is implicated in many developmental processes and in responses to various abiotic stresses, playing pivotal roles in plant adaptation. Deep sequencing technology was chosen to determine the small RNA transcriptome of Saccharum sp cultivars grown on saline conditions. We constructed four small RNAs libraries prepared from plants grown on hydroponic culture submitted to 170mM NaCl and harvested after 1h, 6hs and 24hs. Each library was sequenced individually and together generated more than 50 million short reads. Ninety-eight conserved miRNAs and 33 miRNAs* were identified by bioinformatics. Several of the microRNA showed considerable differences of expression in the four libraries. To confirm the results of the bioinformatics-based analysis, we studied the expression of the 10 most abundant miRNAs and 1 miRNA* in plants treated with 170mM and with a severe treatment of 340mM NaCl. The results showed that 11 selected miRNAs had higher expression in samples treated with severe salt treatment compared to the mild one. We also investigated the regulation of the same miRNAs in shoots of four cultivars grown on soil treated with 170mM NaCl. Cultivars could be grouped according to miRNAs expression in response to salt stress. Furthermore, the majority of the predicted target genes had an inverse regulation with their correspondent microRNAs. The targets encode a wide range of proteins, including transcription factors, metabolic enzymes and genes involved in hormone signaling pathways of, probably assisting the plants to develop tolerance. Our work provides insights into the regulatory functions of miRNAs, thereby expanding our knowledge on potential salt-stressed regulated genes.

Project description:Transcriptional variation, also called expression level polymorphism (ELP), contributes to intra-specific phenotypic variation in many organisms. Differentially expressed transcripts are typically enriched for stress-related genes, suggesting that differences in response to the environment are a particularly common point of divergence among gentoypes. Analysis of ELPs also has been suggested as a way to assess unintended consequences of transgene introduction; however, it is important that interpretation of transcriptional changes be performed within the context of potential fitness effects. In these studies we sought to examine differential gene expression in response to salinity for two widely used Arabidopsis thaliana ecotypes, Wassilewskija (Ws) and Columbia (Col), and a single gene mutation (glabrous, gl1-1) in the Col background (Col(gl)), in relation to genetic, phenotypic, and fitness differences. Growth analyses were performed with seedlings germinated on culture media and growth chamber-grown plants carried through the full life cycle. Transcriptome analyses were performed with salt treated and control growth-chamber grown plants six days post initiation of salt stress. Ws plants had the least salt injury and highest dry matter accumulation and seed production in salt stressed conditions. ELPs among genoytypes and in response to 100 mM NaCl were enriched for genes associated with response to stress, including stress-associated transcription factors, heat shock and redox metabolism genes, and R genes. Application of salt resulted in many more transcripts up- or down-regulated in Col and Ws than in Col(gl). Many of the transcripts influenced by salt in Col were already altered in gl1-1 plants in the absence of salt, although Col(gl) plants did not show any detectable signs of stress, or effects on fecundity in the absence of salt treatment. The majority of salt-induced transcriptional changes that occurred in Ws also occurred in Col, suggesting common salt stress responses in these two ecotypes. Many more genes were affected by salt in Col than Ws, however, possibly reflecting the greater salt injury observed for Col. There was minimal overlap between the transcripts that differed for Ws and Col prior to salt treatment and those that were subsequently affected by salt stress. Thus, many genes conferring comparative salt stress tolerance in Ws likely differ from those whose expression levels are modified in response to salt stress. These studies demonstrate transcriptional variation among Arabidopsis genotypes in response to salt stress. Greater transcriptome differences did not necessarily correspond with greater genetic difference or phenotypic differences in morphology, fecundity, and resistance to salt stress. These results suggest that depending on circumstance, transcriptional changes can reflect response to injury, facilitate adaptive expression of fitness-associated traits, or allow for phenotypic buffering to minimize the impact of genetic changes. Three Arabidopsis genotypes were grown in the growth chamber in the absence and presence of salt stress. Plants from 20 days after sowing (6 days after salt treatment) were used for RNA extraction and hybridization on Affymetrix microarrays. There were two biological replicates for each genotype and salt treatment combination.
