Despite this there exists a huge gap in our understanding regarding the SV-mediated molecular alterations, which is a prerequisite to gain insight into SV-mediated plant development. This strongly suggests the existence of sophisticated molecular mechanisms for SV perception and signal transduction. A number of previous and recent studies reported developmental responses in plants tailored against SV of varied frequencies. Sound vibration (SV) is considered as an external mechanical force that modulates plant growth and development like other mechanical stimuli (e.g., wind, rain, touch and vibration). The recent keymaps button in the lower right corner of 'open keymap' activates a pull-down menu giving one-click access to the 25 most recently saved and loaded keymaps, in the. Soundplant 43 can open older keymaps saved in all previous versions of Soundplant, but saves keymaps in a newer format that can be opened only in versions 40 or later.
Notably, several touch regulated genes were also up-regulated by SV treatment suggesting a possible molecular crosstalk among the two mechanical stimuli, sound and touch. Phytohormonal analysis indicated that SV-mediated responses were, in part, modulated by specific alterations in phytohormone levels especially salicylic acid (SA). Data suggested that like other stimuli, SV also activated signature cellular events, for example, scavenging of reactive oxygen species (ROS), alteration of primary metabolism, and hormonal signaling. As a next step, we also studied the SV-mediated proteomic changes in Arabidopsis.
This mode generates three different forms of conduct: checking, repeating and criticising.Soundplant turns your computer keyboard into a versatile, low latency sound trigger and playable instrument. 2.2 Science as practice and science as an institution. Among these, touch genes ( TCH) are well-known for its touch-mediated rapid up-regulation 2.43. Thigmomorphogenetic responses, which include stunted growth, increase resistance to other stress, alteration in flowering time, senescence, and chlorophyll contents 1, are associated with differential expression of specific genes and proteins.

A direct evidence to this is the elicitation of defense response in Arabidopsis that leads to accumulation of defense molecules upon treatment with vibrations caused by churning sound of caterpillar 3. Thus, it is undeniable that plants have evolved sensitivity also towards sound vibration (SV) of various ecologically relevant frequencies. Developing an environmentally sound plant protection for.All across the biosphere, every niche inhabited by plants is full of vibrations produced by sound of biological and/or physical origin.
It has already been noticed that ultra and infrasound can interact with biological tissues 8. To avoid the controversy, in subsequent work, many researchers preferred single frequency acoustic vibration. Green music itself has been shown to increase oxygen uptake and polyamine content in chinese cabbage 7. Researchers argued that music is a complex mixture of various frequencies, amplitudes and tones, and has neither evolutionary nor ecological significance however, certain natural music (referred as green music), like bird’s singing, cricket’s stridulating and bee’s buzz etc., may be important 6. In preliminary studies, beneficial effect of music on plants was claimed by many researchers though it has been a subject of debate for decades 5. Sound is a vibrational mechanical force and its effect on plants is an emerging area of research for past few years.
SV has been reported to increase protective enzyme activities, cellular sugar, soluble protein, ATP content, and hormones in many different plant species 8, 9, 10. Sound in the range of audible frequencies was also reported to change developmental and physiological processes of plants (e.g., growth, seed germination, cell cycle progression, and plasma membrane architecture) 10.Whereas SV application in agriculture/biotechnology has been an area of much interest, studies suggesting the molecular and physiological effect of SV at cellular level are still at infancy. Employing plant acoustic frequency technology (PAFT), increased photosynthetic characteristics, growth and disease resistance were achieved in various vegetables 8. By virtue of its growth enhancing effect, SV has been widely implicated in agriculture for facilitating crop growth and yield.
Although the above studies suggest that SV has a big impact on plant physiology, these are only preliminary and insufficient to answer many questions at the cellular level. However, more focused research in the future course is required to explore this new area of plant biology.In the light of aforementioned studies, it is amply clear that there exist sophisticated mechanisms in plants for SV perception and associated signal transduction. Additionally, bending of roots of maize seedlings towards the sound source was also shown 14. Previous study has shown that maize seedlings can indeed generate sound in response to SV treatment of specific frequency 14.
We selected all the genes which showed more than 2-fold differential expression ( P 2 to prepare heatmap ( Fig. Maximum number of genes was differentially expressed especially by 500 Hz treatment. Microarray profiling of Arabidopsis plants treated separately with 5 different frequencies (250, 500, 1000, 2000 and 3000 Hz) at constant amplitude (80 dB) suggested differential expression of various genes ( Supplementary Table S1). We forwarded a model of SV-mediated transcriptomic, proteomic and hormonal changes in plant, based on the obtained results.Global Gene Expression Profiling after SV Treatments with Five Different FrequenciesFor microarray analysis, samples were harvested right after the SV treatments of 1 h (0 h time point) to check its immediate effect on global transcriptome ( Supplementary Fig. Additionally, we deciphered the SV-mediated changes in phytohormone levels. Herein, we investigated the global transcriptomic and proteomic changes in Arabidopsis upon exposure to SV of five single frequencies with constant amplitude to bridge this gap.

Twenty-three touch regulated genes were also up-regulated by SV treatments, which are marked as mechanostimulus responsive genes in this group ( Fig. Have shown touch-induced expression of 589 genes (around 2.5% of total genes) in Arabidopsis through microarray analysis 15. Based on their attributes, we classified these 59 genes into following groups.Full size image Group A (Mechanostimulus responsive genes)Lee et al. Heatmap clearly indicated that maximum gene up-regulation occurred by 500 Hz treatment.
Group B (Signaling related genes)Among the up-regulated genes, four were noted to function in cell signaling. Thus, those genes are mentioned in the other groups as well. Notably, several genes categorized in this group are involved in other biological process and/or have different functional role. At1g21910 ( DREB26, encoding an AP2 type TF) showed highest up-regulation by all the treatments.
The other three genes ( MPK11, WAKL2 and CRK41) are kinase family members. The one that showed the highest up-regulation is CML38, encoding Ca 2+ binding calmodulin-like protein. MPK11 and CRK41 are also marked as mechanostimulus responsive genes in the group A ( Fig.
Also, three ethylene response factor (ERF) family members , and three C3H family members were up-regulated by SV treatments. This group also includes two MYB TFs MYB77 (encoding an R2R3 type TF) and MYB44, which were significantly up-regulated by SV treatments. Two of the TFs that showed very high up-regulation at all treatments are DREB26 and At5g22380 ( ANAC090). Out of these 13 genes, 6 TFs are marked as mechanostimulus responsive in the group A: namely: DREB26, At3g50060 ( MYB77), At5g67300 ( MYB44), At5g47220 ( ERF2), At3g55980 ( SZF1), and At1g13260 ( RAV1). Group C (Transcription factors)Total thirteen genes that comprise a variety of TFs constitute this group.
