(Submitter supplied) Halotolerant species are of interest since they occur naturally in environments with excess toxic ions. The cyanobacterium Halothece sp. PCC 7418 (hereafter referred to as Halothece) exhibits remarkable halotolerance and was used to examine stress-responsive regulatory mechanisms. The effects of five different stimuli on Halothece transcriptomes were examined using RNA sequencing. In response to diverse stresses, there were both common and stress-specific transcriptional responses.

(Submitter supplied) Substantial evidence has been accumulated about the molecular basis underlying halotolerance; however, insights into the regulatory networks for relevant genes and mechanisms of their interplay remain elusive. Here, we present a comprehensive transcriptome investigation, using RNA sequencing, of specific metabolic pathways and networks in a halotolerant cyanobacterium, Halothece sp. PCC7418, including the circadian rhythm profile. more...

(Submitter supplied) 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. more...

(Submitter supplied) Soil salinity is one of the primary causes of yield decline in rice. Pokkali (Pok) is a highly salt-tolerant landrace whereas IR29, is salt-sensitive but a widely cultivated cultivar. Comparative analysis of these genotypes may offer better understandings of the salinity tolerance mechanism. The published reports largely underscored the importance of transcriptional regulation during salt stress in these genotypes, while, the regulation at translational level is also critically important. more...

(Submitter supplied) We sought to investigate the scope of transcriptome analyses of peppers subjected to four major environment stresses (heat, cold, drought, and salinity). For this, at the six-true-leaf stage, plants were subjected to a temperature of 10°C or 40°C to mimic cold or heat stress, respectively. For salinity stress, plants were treated with 50 mL of a 400 mM NaCl solution; for osmotic stress, the peppers were treated with 50 mL of 400 mM mannitol. more...

(Submitter supplied) In many habitats, microorganisms are exposed to high or fluctuating salinities and evolved specific acclimation strategies to thrive in those environments. Euryhaline microorganisms can grow in a broad range of salinities, from low ionic strength like freshwater up to twofold seawater salinities. Here, we analyzed the salt acclimation process of the euryhaline model cyanobacterium Synechocystis sp. PCC 6803 in a multi-omics approach by combining transcriptomic, proteomic and metabolomic analyses. The Overall, the comparison of salt-induced proteome and transcriptome changes revealed a good correleation between the proteome and transcriptome that as most the majority of stably up-regulated proteins also showed elevated mRNA transcript levels. However, a dynamic reorganization of the transcriptome occurred during the first hours after salt shock, which probably also involves the action of small regulatory RNAs acting at the post-transcriptional level. In addition to the rapid and stable steady upregulation of compatible solute biochemistry, a dynamic reorganization of the transcriptome occurred during the first hours after salt shock, which probably involves the action of small regulatory RNAs. Moreover, the coordinated induction of several stress proteins known to be involved in iron and oxidative stress responses as well as of mechano-sensitive channels was observed. Based on these data, an extended salt stimulon can be defined comprising many proteins directly or indirectly related to compatible solute metabolism, ion and water movements as well as a defined set of small regulatory RNAs. Moreover, the massive accumulation of the compatible solute glucosylglycerol had large impact on the overall carbon and nitrogen metabolism. Our comprehensive data set provides the basis for future attempts to engineer cyanobacterial salt tolerance and to search for processes regulating this important environmental acclimation process.

A global transcriptomic approach was carried out to determine these molecular mechanisms. S. xylosus modulated the expression of about 30% of the total genes during its growth and survival in the meat model. The expression of many genes encoding enzymes involved in glucose and lactate catabolism was up regulated. more...
