Project description:Seven different Solanaceae species, Potato (Solanum tubersosum), Tomato (Solanum lycopersicum), Eggplant (Solanum melangena), Pepper (Capsicum annuum), Tobacco (Nicotiana tabaccum), Petunia and Nicotiana benthiamana were subjected to salt stress. The stress applied was 150mM NaCl and control plants were watered without the additional salt. Samples were collected at 0, 6, 12, 24, 48 and 96 hours after the first application of the salt. RNA was isolated using Qiagen RNeasy. Keywords: Direct comparison

Project description:Potato seedlings were subjected to cold, heat and salt stress. Expression profiles were captured at three different time-points, 3h, 9h and 27h from two different tissues, roots and leaves. The experiment was preformed independently three times. Commercially available true potato seeds (Variety Gilroy) were germinated on rafts floating on hydroponic medium in Magenta boxes. Plants were grown for 5 weeks prior to stress application under long day conditions (16h light and 8h dark) at 25C with gentle agitation. To initiate stress the medium was replaced with fresh medium pre-chilled to 4C (cold stress), pre-heated to 35C (heat stress) or supplemented with 100mM NaCl (salt stress). Cold and heat stress were maintained for the duration of the experiment by placing the Magenta boxes on ice or in a water-bath at 35C. For every individual sample two boxes of plants were used pooling a total of 6 plants per sample. For each time-point a single control sample was used by changing the media in a similar way as for the stress induction. A total of six boxes were combined for the pooled reference samples. Plants were harvested at the appropriate time and snap-frozen in liquid nitrogen. Roots and aerial tissue was separated prior to freezing. The tissue was stored at -80C freezer until isolation. Total RNA was isolated using RNeasy isolation kit. The intactness of the RNA was verified on gel and the concentration was adjusted to 3ug/ul by ethanol precipitation and re-suspension.

Project description:Salt stress has become one of the main abiotic stress factors restricting agricultural production worldwide. Sweet sorghum is an important salt and drought tolerant feed and energy crop. Its salt tolerance mechanism has not been widely studied. With the development of transcriptome sequencing technology, it is possible to study the molecular mechanism of sweet sorghum salt tolerance. The purpose of this study was to further reveal the potential salt-tolerant molecular mechanisms of sweet sorghum through high-throughput sequencing analysis of the transcriptome. Finally, through high-throughput sequencing, we read approximately 54.4G of raw base and 53.7G of clean base in total, and used FastQC to assign a quality score (Q) to each base in the read using a similar phred algorithm, Analysis shows that the data is highly credible. We conclude that RNA-based transcriptome characterization will accelerate the study of genetics and molecular biology of sweet sorghum salt tolerance mechanisms and provide a framework for this.

Project description:Potato plants are sensitive to multiple abiotic stresses such as drought, low temperature and high light. We analyzed the transcriptome of WT potato plants as well as that of transgenic potato plants expressing the Arabidopsis stress related transcription factor CBF1 that confers tolerance to multiple stresses.

Project description:Soil salinity is a major production constrain for agricultural crops, especially in Oryza sativa (rice). Analyzing physiological effect and molecular mechanism under salt stress is key for developing stress-tolerant plants. Roots system has a major role in coping with the osmotic change impacted by salinity and few salt-stress-related transcriptome studies in rice have been previously reported. However, transcriptome data sets using rice roots grown in soil condition are more relevant for further applications, but have not yet been available. The present work analyzed rice root and shoot physiological characteristics in response to salt stress using 250 mM NaCl for different timepoints. Subsequently, we identified that 5 day treatment is critical timepoint for stress response in the specific experimental design. We then generated RNA-Seq-based transcriptome data set with rice roots treated with 250 mM NaCl for 5 days along with untreated controls in soil condition using rice japonica cultivar Chilbo. We identified 447 upregulated genes under salt stress with more than fourfold changes (p value < 0.05, FDR < 0.05) and used qRT-PCR for six genes to confirm their salt-dependent induction patterns. GO-enrichment analysis indicated that carbohydrate and amino-acid metabolic process are significantly affected by the salt stress. MapMan overview analysis indicated that secondary metabolite-related genes are induced under salt stress. Metabolites profiling analysis confirmed that phenolics and flavonoids accumulate in root under salt stress. We further constructed a functional network consisting of regulatory genes based on predicted protein–protein interactions, suggesting useful regulatory molecular network for future applications.

Project description:Purpose:Identification of genes and miRNAs responsible for salt tolerance in upland cotton (Gossypium hirsutum L.) would help reveal the molecular mechanisms of salt tolerance. We performed physiological experiments and transcriptome sequencing (mRNA-seq and small RNA-seq) of cotton leaves under salt stress using Illumina sequencing technology. And quantitative reverse transcription polymerase chain reaction (qRT–PCR) methods and to evaluate protocols for optimal high-throughput data analysis Methods:We investigated two distinct salt stress phases—dehydration (4 h) and ionic stress (osmotic restoration; 24 h)—that were identified by physiological changes of 14-day-old seedlings of two cotton genotypes, one salt tolerant and the other salt sensitive, during a 72-h NaCl exposure. A comparative transcriptomics approach was used to monitor gene and miRNA differential expression at two time points (4 and 24 h) in leaves of the two cotton genotypes under salinity conditions. Results:During a 24-h salt exposure, 819 transcription factor unigenes were differentially expressed in both genotypes, with 129 unigenes specifically expressed in the salt-tolerant genotype. Under salt stress, 108 conserved miRNAs from known families were differentially expressed at two time points in the salt-tolerant genotype. Conclusions:Our comprehensive transcriptome analysis has provided new insights into salt-stress response of upland cotton. The results should contribute to the development of genetically modified cotton with salt tolerance.
