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.

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: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: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.
