“…It can be seen that, under the "stimulation" of audio control technology, the output of some crops can be effectively improved, which is an effective way to realize pollution-free ecological agriculture. At the same time, the crops themselves may have many physiological changes in the process of "enjoying" audio control technology, which will lead to changes in growth capacity [49][50][51][52]. The present results showed that different plants had different responses to acoustic stimulation at different growth stages, but the mechanism is still unclear.…”

The excessive use of pesticides and fertilizers reduces the quality of crops, harms human health, and causes environmental pollution, thus hindering the sustainable development of agriculture. In the process of realizing ecological agricultural production, audio control technology has increasingly become an area of concern. As a physical agricultural technology, it has become a combination of music acoustics and agricultural science. However, the research on the ecological role and function of audio control technology is still relatively lacking. In view of this, the authors studied the effects of audio control technology (specific frequency sound wave and different types of music) on the growth of lettuce, and showed that the specific frequency sound wave treatment produced by the plant acoustic frequency technology generator significantly increased the growth of lettuce compared with the condition of silent environment processing. Treatments of different types of music (electronic music, rock music, and classical music) promoted lettuce growth, especially the significant increase in the output of edible parts under the influence of electronic music. The research results further showed that the specific frequency sound wave treatment produced by the plant acoustic frequency technology generator enhanced the chlorophyll content of lettuce leaves (1.98 ± 0.15 mg/g), thus promoting photosynthesis. Different types of music had different effects on the photosynthesis of lettuce leaves; electronic music treatment increased the chlorophyll content of lettuce (1.48 ± 0.07 mg/g), and had the greatest impact.

“…Cavitation is the mechanical breakage of the continuous water column in a xylem vessel that occurs when the tensile strength of the water column is exceeded. This is accompanied by the build-up of mechanical pressure, which, when released, leads to elastic wave propagation [11]. In other words, there is an abrupt release of tension in the xylem vessel lumen as the liquid water under negative pressure is replaced by water vapor [52].…”

Plants have long been considered passive, static, and unchanging organisms, but this view is finally changing. More and more knowledge is showing that plants are aware of their surroundings, and they respond to a surprising variety of stimuli by modifying their growth and development. Plants extensively communicate with the world around them, above and below ground. Although communication through mycorrhizal networks and Volatile Organic Compounds has been known for a long time, acoustic perception and communication are somehow a final frontier of research. Perhaps surprisingly, plants not only respond to sound, they actually seem to emit sound as well. Roots emit audible clicks during growth, and sounds are emitted from xylem vessels, although the nature of these acoustic emissions still needs to be clarified. Even more interesting, there is the possibility that these sounds carry information with ecological implications, such as alerting insects of the hydration state of a possible host plant, and technological implications as well. Monitoring sound emissions could possibly allow careful monitoring of the hydration state of crops, which could mean significantly less water used during irrigation. This review summarizes the current knowledge on sound perception communication in plants and illustrates possible implications and technological applications.

“…Chemical ecology and related studies of intra- and inter-organismal signalling mediated by fungi and bacteria such as microbiome research and mycelium communication systems deal with chemical and physical signals and receptors at the level of cells or organisms. The signals are referred to as “infochemicals” and studies suggest that far from stressors leading to uncertain outcomes, the responses are highly controlled [ 71 , 72 , 73 , 74 , 75 ]. Chemicals can be identified and tested, clear hypotheses can be formulated.…”

The role of signalling in initiating and perpetuating effects triggered by deposition of ionising radiation energy in parts of a system is very clear. Less clear are the very early steps involved in converting energy to chemical and biological effects in non-targeted parts of the system. The paper aims to present a new model, which could aid our understanding of the role of low dose effects in determining ultimate disease outcomes. We propose a key role for electromagnetic signals resulting from physico-chemical processes such as excitation decay, and acoustic waves. These lead to the initiation of damage response pathways such as elevation of reactive oxygen species and membrane associated changes in key ion channels. Critically, these signalling pathways allow coordination of responses across system levels. For example, depending on how these perturbations are transduced, adverse or beneficial outcomes may predominate. We suggest that by appreciating the importance of signalling and communication between multiple levels of organisation, a unified theory could emerge. This would allow the development of models incorporating time, space and system level to position data in appropriate areas of a multidimensional domain. We propose the use of the term “infosome” to capture the nature of radiation-induced communication systems which include physical as well as chemical signals. We have named our model “the variable response model” or “VRM” which allows for multiple outcomes following exposure to low doses or to signals from low dose irradiated cells, tissues or organisms. We suggest that the use of both dose and infosome in radiation protection might open up new conceptual avenues that could allow intrinsic uncertainty to be embraced within a holistic protection framework.
