Project description:Sound wave can cause various developmental and physiological changes in plant. It strongly suggests the existence of sophisticated molecular mechanisms for sound perception in plant. Hence gene expression study is important. We investigated the global gene expression in Arabidopsis upon five different single frequency treatment. Sound treated Arabidopsis was used for RNA extraction and hybridization on Affymetrix microarrays. Five different frequency (250, 500, 1000, 2000 and 3000 Hz) was applied at 80 db on 20 days old plant for one hour. Immediate after treatment (0 hour) rosette samples were harvested.

Project description:A deficiency of pejvakin, a protein of unknown function, causes a strikingly heterogeneous form of deafness. Pejvakin-deficient (Pjvk-/-) mice also exhibited variable auditory phenotypes. Correlation between their hearing thresholds and the number of pups per cage suggested a possible harmful effect of pup vocalizations. Direct sound or electrical stimulation showed that the cochlear sensory hair cells and auditory pathway neurons of Pjvk-/- mice and patients were exceptionally vulnerable to sound. Pjvk-/- cochleas displayed features of marked oxidative stress and impaired anti-oxidant defenses. We showed that pejvakin is associated with peroxisomes, and is required for the oxidative stress-induced proliferation of these organelles. In Pjvk-/- hair cells, peroxisomes displayed structural abnormalities after the onset of hearing. Noise-exposure of wild-type mice rapidly upregulated Pjvk cochlear transcription, and triggered peroxisome proliferation in hair cells and primary auditory neurons. Our results reveal that the anti-oxidant activity of peroxisomes protects the auditory system against noise-induced damage.

Three RNA samples was extracted from dissected organ of Corti (OC) for each genotype (Pjvk-/- and Pjvk+/+ mice) and analyzed (triplicate OCmm-1, OCmm-2, and OCmm-3 for Pjvk-/-, and triplicate OCpp-1, OCpp-2, and OCpp-3 for Pjvk+/+).

Project description:We evaluated the molecular mechanism underlying this delaying fruit ripening by performing RNA-sequencing analysis of tomato fruits at 6 h, 2 days (d), 5 d and 7 d after 1 kHz sound vibration treatment. Differentially expressed genes revealed that some of these genes are involved in plant hormone and cell wall modification processes. Ethylene and cytokinin biosynthesis and signalling genes were downregulated by sound vibration treatment, whereas genes involved in flavonoid, phenylpropanoid and glucan biosynthesis were upregulated. Our results indicate that sound vibration helps delay fruit ripening through the sophisticated regulation of RNAs and transcription factor genes.

Project description:Sound vibration (SV), a mechanical stimulus, can trigger various molecular and physiological changes in plants. Herein, we investigated the effect of SV pre-treatment on Arabidopsis immunity to measure the priming potential of SV. Arabidopsis plants (fourteen-day-old) were treated with sound vibration (1000 Hz, 100 dB) for daily 3 hours up to 10 days in a soundproof chamber. The control plants were kept in a similar sound-proof chamber without SV exposure (daily 3 h) up to 10 days. After that, control and SV-treated plants were challenged with Botrytis cinerea spores. The result showed that SV pre-treatment increases the disease resistance of Arabidopsis against B. cinerea. Samples from three different time points were analyzed through microarray: (1) right after the 10th day of 3h SV treatment (0 h time point), and (2) after Botrytis spore inoculation (12 and 24 hpi time points). RNA was isolated from rosette leaves.

Project description:Sound vibration (SV) causes various developmental and physiological changes in plants. It strongly suggests the existence of sophisticated molecular mechanisms for SV perception and signaling in plants. However, the underlying molecular mechanism of SV-mediated plant responses remains elusive. Herein, we investigated the transcript changes in Arabidopsis thaliana upon five different single frequencies of SV treatment.

Project description:Changes in microbiome composition have been associated with a wide array of human diseases, turning the human microbiota into an attractive target for therapeutic intervention. Yet clinical translation of these findings requires the establishment of causative connections between specific microbial taxa and their functional impact on host tissues. Here, we infused gut organ cultures with longitudinal microbiota samples collected from therapy-naïve irritable bowel syndrome (IBS) patients under low-FODMAP (fermentable Oligo-, Di-, Mono-saccharides and Polyols) diet. We show that post-diet microbiota regulates intestinal expression of inflammatory and neuro-muscular gene-sets. Specifically, we identify Bifidobacterium adolescentis as a diet-sensitive pathobiont that alters tight junction integrity and disrupts gut barrier functions. Collectively, we present a unique pathway discovery approach for mechanistic dissection and identification of functional diet-host-microbiota modules. Our data support the hypothesis that the gut microbiota mediates the beneficial effects of low-FODMAP diet and reinforce the potential feasibility of microbiome based-therapies in IBS.
