Project description:Arabidopsis thaliana and Arabidopsis lyrata are two closely related Brassicaceae species, which are used as models for plant comparative biology. They differ by lifestyle, predominant mating strategy, ecological niches and genome organization. To identify heat stress induced genes, we performed RNA-sequencing of rosette leaves from mock-treated, heat-stressed and heat-stressed-recoved plants of both species. Analysis of genetic element transcriptional changes in response to 6 hours of 37°C heat stress and 48 hours of recovery in Arabidopsis thaliana Col-0 and Arabidopsis lyrata MN47.

Project description:In order to investigate possible roles of IDL and PIP/PIPL peptides, the transcriptomic response of Arabidopsis seedlings to treatment with PIPL3 peptide was analysed. PIPL3 (At4g37295) was chosen, as no functional data was available for this peptide; furthermore, PIPL3 was expressed in leaf tissue during seedling stages. Transcriptomic responses to 3 hours PIPL3 peptide treatment suggested a role in regulation of biotic stress responses and cell wall modification.

Project description:Environmental stress is detrimental to plants viability and requires an adequate reprogramming of cellular activities to maximize plant survival. We present a global analysis of the adaptive stress response of Arabidopsis thaliana to prolonged heat stress. We combine deep sequencing of RNA and ribosome protected fragments to provide genome wide map of adaptation to heat stress on at transcriptional and translational level. Our analysis shows that the genes with the highest upregulation upon heat stress are known heat-responsive gene, chaperons and other genes involved in protein folding control. Majority of these genes exhibits increase on both transcriptional and translational level. No translational inhibition or ribosome stalling was observed, which can be observed in the early thermal stress response, indicating that plants alter their cellular composition in order to adapt to the prolonged exposure to increased temperatures.

Project description:Analysis of transcriptional changes upon persistent heat stress with emphasis on epigenetically regulated genes 3 week old seedling grown in vitro were exposed to 37oC for 30 h (LHS). After heat stress, plants were analyzed immediately (R0) or allowed to recover at ambient temperature for 2 days (R2).

Project description:Arabidopsis plants that have experienced stress from water withdrawal show an improved ability to tolerate subsequent exposures as a ‘memory’ from the previous stress. This physiological stress memory is associated with ‘transcriptional memory’ illustrated by a subset of dehydrations stress responding genes that produce significantly different transcript amounts during repeated dehydration stresses relative to their response in the first. Here we report the genome-wide representation of dehydration stress transcriptional memory genes in A. thaliana. We identify four novel transcription patterns in response to repeated dehydration stress treatments. The nature of the proteins encoded by genes from each type of memory-response pattern is analyzed and the consequences of the genes’ memory behavior are considered in the context of possible biological relevance. The memory behavior of genes co-regulated by the dehydration/ABA and other abiotic stress and hormone responding pathways suggested that the crosstalk at the transcriptional level between them was affected as well. The intensity and the nature of specific biochemical, membrane, chloroplast, and stress response-related interactions during multiple exposures to dehydration stress are different from the responses to a single dehydration stress. The results reveal additional, hitherto unknown, levels of complexity of the plants’ transcriptional behavior when adjusting and adapting to recurring water deficits.

Transcriptomic responses to 3 hours PIPL3 peptide treatment suggested a role in regulation of biotic stress responses and cell wall modification. Two weeks old seedlings were treated either with 100 nM PIPL3 peptide (treated) or 100 nM mock peptide (control) and whole rosettes were harvested 3 hours after treatment. 4 biological replicates per treatment.

For each condition (water, S1, and S3) the transcriptome was sequenced for two replicates. The watered condition is considered the control.
