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:Phytochromes mediate a profound developmental shift when dark-grown seedlings are exposed to light. Here we show that a subset of genes is up regulated in phytochrome B (phyB) mutants even before dark-grown seedlings are exposed to light. Most of these genes bear the RY cis motif, which is a binding site of the transcription factor ABSCISIC ACID INSENSITIVE 3 (ABI3), and the phyB mutation also enhanced ABI3 expression. These changes in transcriptome have physiological consequences as seedlings of the abi3 mutant showed enhanced responses to pulses of far-red light, while ABI3 overexpressers exhibited the opposite pattern. Seedlings of the wild type derived from seeds germinated in full darkness showed enhanced expression of genes bearing the RY cis motif and reduced responses to far-red light. We propose that, via changes in ABI3 expression, light, perceived mainly by phyB in the seed, generates a downstream trans-developmental phase signal that pre-conditions the seedling to its most likely environment.

Project description:Light, an important environmental factor regulates most of plant physiology and development. In the photomorphogenic stage, light globally enhances translation status in de-etiolating Arabidopsis seedlings. More than 1500 genes showed increased translation but not transcription in this developmental process. This implies these mRNAs are translationally repressed in dark-grown seedlings. Through transcriptome and translatome comparisons, we revealed that p-bodies attenuate the translation of mRNAs in the etiolated seedlings. We found hundreds of mRNAs accumulated and also increased translation for thousands of genes in dark-grown dcp5-1, including genes known to regulate the transition from skotomorphogenesis to photomorphogenesis. Our data reports p-bodies regulate both RNA stability and attenuation of translation for specific mRNAs in the dark.
