The Arabidopsis spaceflight transcriptome: a comparison of whole plants to discrete root, hypocotyl and shoot responses to the orbital environment

ABSTRACT: Arabidopsis thaliana was evaluated for its response to the spaceflight environment in three replicated experiments on the International Space Station. Two approaches were used; GFP reporter genes were used to collect gene expression data in real time within unique GFP imaging hardware, and plants were harvested on orbit to RNAlater for subsequent analyses of gene expression with using Affymetrix and SAGE transcriptome analyses. Three tissue types were examined (leaves, hypocotyls and roots) and compared to analyses conducted with whole plants. Transcriptome analyses with whole plants suggested that the spaceflight environment had little impact on the transcriptome of arabidopsis, however, closer examination of selected tissues revealed that there are a number of tissue-specific responses that arabidopsis employs to respond to this novel environment

<h4>Background</h4>Spaceflight presents a novel environment that is outside the evolutionary experience of terrestrial organisms. Full activation of the International Space Station as a science platform complete with sophisticated plant growth chambers, laboratory benches, and procedures for effective sample return, has enabled a new level of research capability and hypothesis testing in this unique environment. The opportunity to examine the strategies of environmental sensing in spaceflight, w ...[more]

Project description:Relatively little is known about the presence and regulation of pathways involved in nutrient acquisition in the brown tide forming alga, Aureococcus anophagefferens. In this study, Long-SAGE (Serial Analysis of Gene Expression) was used to profile the A. anophagefferens transcriptome under nutrient replete (control), and nitrogen (N) and phosphorus (P) deficiency with the goal of understanding how this organism responds at the transcriptional level to varying nutrient conditions. This approach has aided A. anophagefferens genome annotation efforts and identified a suite of genes up-regulated by N and P deficiency, some of which have known roles in nutrient metabolism. Genes up-regulated under N deficiency include an ammonium transporter, an acetamidase/formamidase, and two peptidases. This suggests an ability to utilize reduced N compounds and dissolved organic nitrogen, supporting the hypothesized importance of these N sources in A. anophagefferens bloom formation. There are also a broad suite of P-regulated genes, including an alkaline phosphatase, and two 5’-nucleotidases, suggesting A. anophagefferens may use dissolved organic phosphorus under low phosphate conditions. These N- and P-regulated genes may be important targets for exploring nutrient controls on bloom formation in field populations. Aureococcus anophagefferens CCMP 1984 was obtained from the Provasoli-Guillard Center for the Culture of Marine Phytoplankton (CCMP). The cultures were grown at 18C on a 14 h:10 h light:dark cycle (140 µmol quanta m-2 s-1). Nitrogen- and phosphate-replete (883 µM NO3- and 36.3 µM PO43-) cells, –N (40 µM NO3-) cells, and –P (1 µM PO43-) cells were grown in autoclaved L1 media with no Si (Guillard and Hargraves 1993), prepared using 0.2 µm filtered Vineyard Sound seawater. Vitamins (thiamine, biotin, and B12) were sterile filtered and added to the media after autoclaving. Replete cells were harvested during mid log phase of growth, while –N and –P cells were harvested at the onset of stationary phase when N or P was depleted.

Project description:We determined the strand-specific transcriptome of the fission yeast S. pombe under multiple growth conditions using a novel RNA/DNA hybridization mapping (HybMap) technique. HybMap uses an antibody against an RNA/DNA hybrid to detect RNA molecules hybridized to a high density DNA oligonucleotide tiling microarray. HybMap exhibited exceptional dynamic range and reproducibility, and clearly revealed coding, non-coding and structural RNAs, as well as new RNAs conserved in distant yeast species. Virtually the entire euchromatic genome (including intergenics) is transcribed, with heterochromatin dampening intergenic transcription. Transcriptomes of alternative growth conditions reveal changes in both coding and non-coding RNAs. Interestingly, our analysis reveals large numbers of non-coding RNAs, extensive antisense transcription, new properties of antisense transcripts, and induced divergent transcription. Furthermore, HybMap informed the efficiency and locations of RNA splicing genome-wide. Finally, a remarkable feature is observed at heterochromatin boundaries inside centromeres; strand-specific transcription islands around tRNAs. These new features are discussed in terms of organism fitness and transcriptome evolution. Keywords: yeast, gene expression, bioinformatics The dynamic transcriptome of S.pombe was determined using a whole genome tiling array hybridized to total RNA. Transcripts were detected using an antibody specific to RNA/DNA hybrids. This technique, called HybMap, was used across three different growth conditions (Heat shock, MMS treatment, and minimal media) in addtion to standard conditions. To further understand the transcriptome, we isolated PolyA RNA from S.pombe grown in standard conditions and used the HybMap method. Finally, the transcriptome was compared to Pol II, histone, and H3K36me3 ChIP occupancy. NOTE: Processed microarray data values listed in this repository represent only those probes that align to unique genomic positions. Probes that align to multiple genomic locations (reported in the Platform description) may not have values. Please refer to the web link above for a complete genomic data set.
