Project description:Autophagy involves massive degradation of intracellular components and functions as a conserved system that helps cells to adapt to adverse conditions. In Arabidopsis thaliana, submergence induces the transcription of autophagy-related (ATG) genes and the formation of autophagosomes. To study the role of autophagy during submergence, we performed transcriptome analysis with atg5, an autophagy-defective mutant, under submergence conditions. Our data showed that submergence changed the expression profile of DEG in the atg5 versus wild-type.

Project description:Heavy rainfall causes flooding of natural ecosystems as well as farmland, negatively affecting crop performance and yield. While the response of the wild model organism Arabidopsis thaliana to such stress conditions is well understood, we hardly know anything about the response of its relative, the important oil crop plant Brassica napus. Here, we analyzed the molecular response of leaves of rapeseed seedlings to full submergence under illumination. RNAseq experiments revealed a strong carbon starvation response under submergence, but no indication for a low-oxygen response. We used two cultivars in this study, one Asian flooding-tolerant cultivar and one European hybrid cultivar, but those genotypes did not show strong differences in their responses to submergence.

Project description:This study profiles transcriptomic changes of Arabidopsis thaliana Col-0 in response to submergence. This dataset includes CEL files, RMA signal values and MAS5 P/M/A calls from total mRNA populations of plants at 9 to 10 leaf rosette stage. Biological replicates of root and shoot tissues were harvested after 7 h and 24 h of submergence in darkness along with corresponding non-submerged dark controls. To characterize the dark response, non-submerged light controls plants were harvested at the 0 h time point. Quantitative profiling of cellular mRNAs was accomplished with the Affymetrix ATH1 platform. Changes in the transcriptome in response to submergence and early darkness were evaluated, and the data led to identification of genes co-regulated at the conditional and organ-specific level.

Project description:RNA sequencing (RNA-seq) was performed to investigate potential roles of the unfolded protein response in submergence and recovery responses of Arabidopsis thaliana. Plants were grown to the 10-leaf stage and then subjected to 4 days of complete submergence. Samples were collected at four time points: prior to submergence (T0), after 1 day of submergence (1d), after 4 days of submergence (4d - end of submergence period), and 3 hours after de-submergence (recovery). For each time point, rosettes were collected and divided into two developmental zones: (i) old leaves (leaves 1 to 5) and (ii) young leaves (leaves 6 to 10 including the shoot apical meristem (SAM)). There were three biological replicates per tissue type of each genotype at each time point. Each biological replicate consisted of tissue pooled from two plants. Two genotypes were examined: Col-0 (wild type) and the bzip60/bzip28 double mutant, which is impaired in unfolded protein response signaling. RNA-seq libraries were prepared using the Illumina TruSeq Stranded mRNA protocol and sequenced on an Illumina platform to generate paired-end reads.

Project description:Arabidopsis plants display superior tolerance to submergence at the juvenile stage. We characterized the transcriptomic response to submergence in juvenile and adult plants. In this dataset, we include expression data from 2-week and 3-week old plants under dark air and dark submergence conditions.

Project description:Pot grown plants of Arabidopsis thaliana, Cardamine hirsuta, Cardamine pratensis, Rorippa palustris and Rorippa sylvestris where completely submerged under ambient light conditions. After 24 and 48 hours the shoots were harvested for expression analysis. Differential expression analysis, taking into account unsubmerged control plants revealed that the Rorippa genus had a pronounced down regulation of the cell cycle whereas the Cardamine had an attenuated response to submergence.
