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.
Dissecting transcriptional responses of nucleolin mutants to red light stimulation and darkness in ground reference conditions
Understanding plant adaptive responses to the space environment is a requisite for enabling space farming. Spaceflight produce deleterious effects on plant cells particularly affecting ribosome biogenesis a complex stress-sensitive process coordinated with cell division and differentiation known to be activated by red light. Here we have used mutants from the two nucleolin genes in Arabidopsis (NUC1 and NUC2) encoding the main regulator of the ribosome biogenesis in the nucleolus in order to better understand their role in adaptive response mechanisms to stress. Thus we show that nucleolin stress-related gene NUC2 can compensate the environmental stress provided by darkness in nuc1 plants while nuc2 plants are not able to provide a complete response to red light. These ground control findings as part of the ESA/NASA Seedling Growth spaceflight experiments will determine the basis for the identification of a genetic background enabling an adaptive advantage for plants in future space experiments.
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.
Adaptive response of Arabidopsis seedlings in microgravity and Mars reduced gravity environment is enhanced by red light photostimulation
The response of plants to the spaceflight environment and microgravity is still not well understood although there has been an increased emphasis on this topic. Even less is known about plants response to partial or reduced gravity levels. In the absence of the directional cues provided by the gravity vector the plant is especially perceptive to other cues such as light. Here we investigate the response of Arabidopsis thaliana 6-day-old seedlings to microgravity and the Mars partial gravity level during spaceflight as well as the effects of red light photostimulation by determining meristematic cell growth and proliferation. These experiments involve microscopic techniques together with transcriptomic studies. We demonstrate that microgravity and partial gravity trigger differential responses. The microgravity environment activates hormonal routes responsible for proliferation/growth and upregulates plastid/mitochondrial-encoded transcripts even in the dark. In contrast the Mars gravity level inhibits these routes and activates responses to stress factors to restore cell growth parameters only when red photostimulation is provided. This response is accompanied by upregulation of numerous transcription factors such as the environmental acclimation-related WRKY family. In the long term these discoveries can be applied in the design of bioregenerative life support systems and space farming.
