Project description:We evaluated differential RNA-seq coverage of all TAIR10-annotated introns in Arabidopsis seedlings subjected to heat stress. Transcriptome analyses of plants infected with bacteria suggested the untreated upf1-5 mutant was enriched not only with pathogen defense-associated mRNAs but also with transcripts encoding genes involved in the general abiotic stress responses. Therefore, we reasoned that global IR events in the upf1-5 mutant and in environmentally stressed wild-type plants may show similarities. Indeed, the transcriptomes of upf1-5 mutant and the heat-stressed wild-type seedlings shared an overlapping set of differentially expressed introns
Project description:Small RNA sequences from Arabidopsis thaliana Col-0 inflorescence tissues of three biological replicates. The data were analyzed to identify non-templated nucleotides in Arabidopsis small RNAs.
Project description:Plants often face combinatorial stresses in their natural environment. Here arsenic (As) toxicity was combined with hypoxia (Hpx) in the roots of Arabidopsis thaliana as it often occurs in nature. The present work aimed to explore the effects of single and combined hypoxia and As stress applied at realistic stress levels to hydroponically grown A. thaliana. Arsenic as well as hypoxic growth conditions generate a characteristic signaling pattern, a significant part of which is mediated by ROS. The current study utilized the microarray to determine the overlapping signalling pattern and changes in gene expression for the defined stress combinaton compared to individual stresses.
