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: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: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.

Project description:Plant can perceive and respond natural sound vibration (SV). Artificial SV also served as a novel trigger of induced resistance, although approaches for activating such plant innate immunity intensively studied on the use of biological and chemical agents (BCA). Artificial SV pre-treatment protected Arabidopsis thaliana seedlings against insect pests and fungal pathogens. However, SV-mediated epigenetic modulation remains unexplored while CBA-mediated induced resistance is known as a complicated process involving epigenetic regulation. Here, we performed a ChIP-seq analysis to understand the role of 10 kHz SV-mediated epigenetic modification in induced resistance against a soil-borne pathogenic bacterium Ralstonia solanacearum.

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:Cochlear hair cells (HCs) in the inner ear are responsible for sound detection. For HC fate specification, the master transcription factor Atoh1 is both necessary and sufficient. Atoh1 expression is dynamic and tightly regulated during development, but the cis-regulatory elements mediating this regulation remain unresolved. Unexpectedly, we found that deleting the only recognized Atoh1 enhancer, defined here as Eh1, failed to impair HC development. By using ATAC-seq (assay for transposase-accessible chromatin with high-throughput sequencing), we discovered two additional Atoh1 enhancers: Eh2 and Eh3. Notably, Eh2 deletion was sufficient for impairing HC development, and concurrent deletion of Eh1 and Eh2 or all three enhancers resulted in nearly complete absence of HCs. Lastly, we showed that Atoh1 binds to all three enhancers, consistent with its autoregulatory function. Our findings reveal that the cooperative action of three distinct enhancers underpins effective Atoh1 regulation during HC development, indicating potential therapeutic approaches for HC regeneration.
