Project description:Plants transcriptome react to environment temperature changes profoundly. In Arabidopsis seedlings, genes respond to temperature fluctuations to adopt the ever-changing ambient environment. We used microarrays to detail the global programme of gene expression underlying heat stress response progress in Arabidopsis. Ten-day-old Arabidopsis seedlings were selected for RNA extraction and hybridization on Affymetrix microarrays. We sought to explore the heat stress response in transcriptome, thus we treat the plants with heat stress. While in order to identify the interaction between light and temperature signaling pathways in plant , we treat Arabidopsis with heat stress under both light and dark conditions. To that end, our plant tissues are grouped as: HS-LIGHT, HS-DARK,CONTROL-LIGHT,CONTROL-DARK.

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.
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
