RNAseq analysis of the response of Arabidopsis thaliana to fractional gravity under blue-light stimulation during spaceflight
Traveling to nearby extraterrestrial objects having a reduced gravity level (partial gravity) compared to Earth's gravity is becoming a realistic objective for space agencies. The use of plants as part of life support systems will require a better understanding of the interactions among plant growth responses including tropisms, under partial gravity conditions. Here, we present results from our latest space experiments on the ISS, in which seeds of Arabidopsis thaliana were germinated, and seedlings grew for six days under different gravity levels, namely micro-g, several intermediate partial-g levels, and 1g, and were subjected to irradiation with blue light for the last 48 hours. RNA was extracted from 20 samples for subsequent RNAseq analysis. Transcriptomic analysis was performed using the HISAT2-Stringtie-DESeq pipeline. Differentially expressed genes were further characterized for global responses using the GEDI tool, gene networks and for Gene Ontology (GO) enrichment.
Comparative gene expression analysis in the Arabidopsis thaliana root apex using RNA-seq and microarray transcriptome profiles
The root apex is an important section of the plant root involved in environmental sensing and cellular development. Analyzing the gene profile of root apex in diverse environments is important and challenging especially when the samples are limiting and precious such as in spaceflight. The feasibility of using tiny root sections for transcriptome analysis was examined in this study. To understand the gene expression profiles of the root apex Arabidopsis thaliana Col-0 roots were sectioned into Zone-I (0.5 mm root cap and meristematic zone) and Zone-II (1.5 mm transition elongation and growth terminating zone). Gene expression was analyzed using microarray and RNA seq. Both the techniques arrays and RNA-Seq identified 4180 common genes as differentially expressed (with > two-fold changes) between the zones. In addition 771 unique genes and 19 novel TARs were identified by RNA-Seq as differentially expressed which were not detected in the arrays. Single root tip zones can be used for full transcriptome analysis; further the root apex zones are functionally very distinct from each other. RNA-Seq provided novel information about the transcripts compared to the arrays. These data will help optimize transcriptome techniques for dealing with small rare samples.
RNAseq analysis of the response of Arabidopsis thaliana phytochrome mutants (PhyA PhyB) to fractional gravity under blue-light stimulation during spaceflight
Traveling to nearby extraterrestrial objects having a reduced gravity level (partial gravity) compared to Earth s gravity is becoming a realistic objective for space agencies. The use of plants as part of life support systems will require a better understanding of the interactions among plant growth responses including tropisms under partial gravity conditions. Here we present results from the Seedling Growth space experiments on the ISS to complement the previously released GLDS-251 dataset including seeds of Arabidopsis thaliana wildtype plants. Seeds were germinated and seedlings grew for six days under different gravity levels namely micro-g several intermediate partial-g levels and 1g and were subjected to irradiation with blue light for the last 48 hours. RNA was extracted was obtained for 20 wildtype samples for subsequent RNAseq analysis in GLDS-251 here we add 36 samples from similarly exposed PhyA and PhyB mutants.
An environment with strong gravitational and magnetic field alterations synergizes to promote variations in Arabidopsis thaliana callus global transcriptional state
Using diamagnetic levitation we have exposed A. thaliana in vitro callus cultures to five environments with different levels of effective gravity (from levitation i.e. simulated mg* to 2g*) and magnetic fields (10.1 to 16.5 Tesla) and we have compared the results with those of similar experiments done in a Random Position Machine (simulated micro g) and a Large Diameter Centrifuge (2g) free of high magnetic fields. Microarray analysis indicates that there are changes in overall gene expression of the cultured cells exposed to these unusual environments but also that gravitational and magnetic field produce synergic variations in the steady state of the transcriptional profile of A. thaliana. Significant changes in the expression of structural abiotic stress and secondary metabolism genes were observed into the magnet field. These results confirm that the strong magnetic field both at micro g* or 2g* has a significant effect on the expression of these genes but subtle gravitational effects are still observable. These subtle responses to microgravity environments are opposite to the ones observed in a hypergravity one. seven-condition experiment MM2D Arabidopsis culture callus control vs. Treatment (altered gravity simulation GBF). Three GBF were used (LDC (2g) + control RPM (mg) + control and Magnet (mg* 0.1g* 1g* 1.9g* 2g*) + control). Biological replicates: 3 replicates in all conditions and controls except 1.9g* (2 replicates)
