Exploring diurnal rhythm in Brachypodium distachyon transcriptome through time-course RNAseq

Project description:Plants are continuously exposed to varying environmental conditions; some anticipated diurnal changes in light and temperature and others far less predictable. Key to adaptation to a diurnal environment is the anticipation provided by the circadian clock, which coordinates broad changes in gene expression with a period of about 24 h.Here we present the analysis of RNA sequencing to measure transcript abundance over time in Brachypodium distachyon entrained in photo- and thermocycles then transferred to photocycles or thermocycles alone, or constant light and temperature conditions.

Transcriptome profiling reveals insight into the cold response of perennial ryegrass genotypes with contrasting cold tolerance

Project description:Knowledge about molecular mechanisms underlying cold and freezing stress responses in perennial ryegrass is scarce. The current study aims to study cold and freezing stress responses of perennial ryegrass genotypes with contrasting cold tolerances. A panel of 160 genotypes were screened for cold tolerances based on electrolyte leakage % measured after 24 hrs at 12 °C and 24 hrs at 14 °C. Among them, 4 genotypes (2 low EL% and 2 high EL%) were selected to study cold and freezing stress responses. Plants were sampled at 6 timepoints; control (T1), beginning of cold acclimation (T2), 2 weeks into cold acclimation (T3), end of cold cold acclimation (T4), -5°C (T5), -10 °C (T6) followed by RNA extraction and sequencing.

Gene Expression During Recovery from Freezing

Project description:Freezing causes physiological changes even in a hardy, cold-acclimated wild type. During recovery from freezing, gene expression will reflect the induction of damage-repair processes distinct from the damage-prevention associated with cold acclimation. This will be detected by observing the wild-type transcriptome at two time points during recovery from a freezing episode. The appropriate control is the unfrozen, cold-acclimated wild type.

Brassinosteroids participate in the control of basal and acquired freezing tolerance of plants

Project description:Brassinosteroids (BRs) are growth-promoting plant hormones that play a role in abiotic stress responses, but molecular modes that enable this activity remain largely unknown. Here we show that BRs participate in the regulation of freezing tolerance. BR signaling-defective mutants of Arabidopsis thaliana were hypersensitive to freezing before and after cold acclimation. The constitutive activation of BR signaling, in contrast, enhanced freezing resistance. Evidence is provided that the BR-controlled basic helix–loop–helix transcription factor CESTA (CES) can contribute to the constitutive expression of the C-REPEAT/DEHYDRATION-RESPONSIVE ELEMENT BINDING FACTOR (CBF) transcriptional regulators that control cold responsive (COR) gene expression. In addition, CBF-independent classes of BR-regulated COR genes are identified that are regulated in a BR- and CES-dependent manner during cold acclimation. A model is presented in which BRs govern different cold-responsive transcriptional cascades through the posttranslational modification of CES and redundantly acting factors. This contributes to the basal resistance against freezing stress, but also to the further improvement of this resistance through cold acclimation. We used microarray data to investigate the contribution of different pathways to cold tolerance of Arabidopsis thaliana .

Proteomic analysis of the apoplast reveals a differential cold acclimation response among winter wheat crown tissues

Project description:The crown is the critical region for survival of winter wheat exposed to low temperature stresses. When wheat is exposed to non-freezing low temperatures, they can increase their freezing tolerance (cold acclimation, ACC). Changes within the apoplast are thought to be crucial for acquisition of freezing tolerance. However, how individual tissues within the ccrown, namely the shoot apical meristem (SAM, responsible for new shoot growth) and vascular transition zone (VTZ, located at the base of the crown)enhance tolerance to freezing has not yet been characterized. In the present study, we conducted shotgun proteomic analysis of the apoplast fluid to investigate ACC-induced proteins in the SAM and VTZ.

Impact of heavy metals on cold acclimation of Salix viminalis roots

Project description:Frost is a major abiotic stress limiting plant growth and development. Climate change models predict an increase in the magnitude and frequency of late-frost events, which, together with an observed loss of soil insulation, will significantly damage roots. To withstand freezing stress, plants have evolved an adaptative process known as cold acclimation. While this process is well documented, it is known that the plant response to multiple stresses is unique and cannot be deduced from the response to each stress taken separately. Here, we investigate the impact of long-term metal exposure on the cold acclimation of Salix viminalis roots. To do so, we used physiological, transcriptomic and proteomic approaches. We found that while metal exposure significantly affected plants morphology and physiology, it did not impede cold acclimation. The impact of the simultaneous exposure to metals and cold acclimation on the transcriptome was unique, while at the proteomic level, the cold acclimation component seemed to be dominant. Further analysis revealed that metals strongly and negatively impacted the cellular antioxidant system. While this should have led to a loss of frost tolerance, it was not observed. A group of proteins was identified that could have played a role in compensating the impediment of the antioxidative system in metal-exposed roots.

Cold acclimation in the sfr3-1 mutant

Project description:The sfr3-1 mutation causes freezing-sensitivity in Arabidopsis thaliana. The mutated gene has been identified by positional cloning and is currently being characterised. The mutant appears normal when grown in the warm (no phenotype has been identified associated with such growth). However, following cold acclimation and subsequent freezing mutant plants are severely damaged whilst wild type plants are not. This suggests that sfr3 is deficient in the cold acclimation process. Micro-array analysis will enable the identification of any transcriptional changes during the cold acclimation process. This information will then be used, together with information obtained by gene characterisation, in order to more fully understand the nature of the sfr3 mutation.

Larvae of Drosophila melanogaster exhibit transcriptional activation of immune response pathways and antimicrobial peptides during recovery from supercooling stress

Project description:The biochemical and molecular mechanisms of insect cold acclimation prior to cold stress have been relatively well explored. The mechanisms linked to recovery and repair after cold stress received much less attention.Here we focus on recovery from cold stress in the larvae of vinegar fly (Drosophila melanogaster) that were exposed to two physiologically distinct cold stress situations; supercooling (S, survival > 90%) and freezing (F, survival < 10%), both at -5°C.The transcriptomic responses to cold stress were analyzed.
