Surviving Mars: The role of black fungus Rhinocladiella similis in understanding life in perchlorate-rich environments

ABSTRACT: The study of the survival of terrestrial microorganisms in Martian conditions, especially in the presence of perchlorates, offers crucial insights for astrobiology. This research investigates the resilience of the extremophilic black fungus Rhinocladiella similis to the exposure to magnesium perchlorate and UV-C radiation, simulating a Martian environment. The results show that R. similis, previously known for its remarkable tolerance to acidic conditions, exhibits significant resistance to UV-C radiation combined with perchlorate and high concentrations of magnesium perchlorate.

Gene expression in a 3-dimensional reconstructed human corneal epithelial tissue after near-infrared irradiation simulating solar near-infrared radiation that reaches human tissues on the Earthâs surface

Project description:To clarify the effects of near-infrared radiation, we assessed DNA microarray after water-filtered broad-spectrum near-infrared (1100-1800 nm together with a water-filter that excludes wavelengths 1400-1500 nm) irradiation. We performed 5 rounds of near-infrared irradiation (at 10 J âcm2) using 2 sets of transparent polycarbonate plates, one to block UV and the other to block both UV and near-infrared.

Transcriptional response to UV treatment in several Arabidopsis thaliana accessions

Project description:UV radiation is a ubiquitous component of solar radiation that affects plant growth and development. Analysis of natural variation in response to UV radiation revealed significant differences among natural accessions of Arabidopsis thaliana. However, the genetic basis of this is to a large extent unknown. Here, we analyzed the response of Arabidopsis accessions to UV radiation stress by performing RNA-sequencing of three UV sensitive and three UV resistant accessions. The genome-wide transcriptional analysis revealed a large number of genes significantly up- or down-regulated only in sensitive or only in resistant accessions, respectively. Mutant analysis of few selected candidate genes suggested by the RNA-sequencing results indicate a connection between UV radiation stress and plant-pathogen-like defense responses.

p38-MK2 signaling axis regulates RNA metabolism after UV light-induced DNA damage

Project description:Ultraviolet (UV) light radiation induces the formation of bulky photoproducts in the DNA that interfere with replication and transcription. Recent studies showed that exposure of human cells to UV light globally affects transcription and alternative splicing, however, the signaling pathways and mechanisms that link UV light-induced DNA damage to RNA metabolism regulation remain poorly understood. Here, we provide a systems view on protein phosphorylation patterns induced by UV light, and uncover the dependencies of phosphorylation events on the canonical DNA damage signaling mediated by ATM/ATR or p38 MAP kinase pathway. We identify RNA binding proteins as primary targets and 14-3-3 family as direct readers of p38-MK2-dependent phosphorylation induced by UV light. Moreover, we show that MK2 phosphorylates the RNA binding subunit of the NELF complex NELFE on S115. NELFE phosphorylation promotes the recruitment of 14-3-3 and rapid dissociation of the NELF complex from chromatin that is accompanied with an increase in transcriptional elongation.

Transcription profiling of lettuce in response to UV-B radiation

Project description:UV-B radiation is one of the major environmental stresses that triggers a variety of plant responses. However, limited information is available regarding plant biological reactions which help to circumvent the potentially harmful effects of UV-B radiation in lettuce (Lactuca sativa L.). In this study, RNA-seq was performed to identify differentially expressed genes in response to UV-B radiation.

Project description:To explore possible interactive effects of UV-radiation, temperature and growth conditions, cultivated and field sporophytes of Saccharina latissima were exposed for 24h to UV-radiation at three different temperatures (2,7 & 12°C). Gene expression profiles under UV-radiation at different temperatures were assessed through microarray hybridizations, afterwards comparisons of gene expression profiles in field and culture sporophytes were carried out.

Root transcriptome remodeling of Arabidopsis in response to high levels of magnesium sulfate

Project description:Martian regolith (unconsolidated surface material) is a potential medium for plant growth in bioregenerative life support systems during manned missions on Mars. However, hydrated magnesium sulfate mineral levels in the regolith of Mars can reach as high as 10 wt%, and would be expected to be highly inhibitory to plant growth. A global approach was used to identify novel genes with potential to enhance tolerance to high MgSO4 stress. The early Arabidopsis root transcriptome response to elevated concentrations of magnesium sulfate was characterized in col-0, and also between col-0 and the mutant line cax1-1 – a mutant relatively tolerant of high levels of MgSO4•7H2O in soil solution. After 3 weeks of growth under hydroponic conditions, Arabidopsis thaliana col-0 roots were exposed to a basic nutrient solution (0.25 g/L MES, 1/16x MS, pH 5.7) with an additional 2.08 mM magnesium sulfate (total Ca:Mg ratio = 1:15) for 45 min., 90 min., or 180 min., while a col-0 control set was exposed to the basic nutrient solution without additional magnesium sulfate for 45 minutes. Arabidopsis thaliana cax1-1 roots were exposed to the basic nutrient solution with additional magnesium sulfate for 180 min. only. Four replicate containers were harvested for the control and each of the treatment sets, resulting in a total of 20 samples. Gene expression of the col-0 sets exposed to magnesium sulfate treatment for 45 min., 90 min., or 180 min. was compared to gene expression of the col-0 control set. Gene expression of the cax1-1 set exposed to magnesium sulfate treatment for 180 min. was compared to gene expression of the col-0 set exposed to magnesium sulfate treatment for 180 minutes.
