To test the sound’s effect on plant and its contribution in drought tolerance, plants were subjected to various sound frequencies for an hour. After 24 h sound treatment, plants were exposed to drought for next five days. During the experiment it was observed that sound initiated physiological changes showing tolerance in plant. Sound frequency with ≥ 0.8 kHz enhanced relative water content, stomatal conductance and quantum yield of PSII (Fv/Fm ratio) in drought stress environment. Hydrogen…

Positive regulatory role of sound vibration treatment in Arabidopsis thaliana against Botrytis cinerea infection

It is proposed that SV treatment invigorates the plant defense system by regulating the SA-mediated priming effect, consequently promoting the SV-induced resistance in Arabidopsis against B. cinerea.

Plant acoustics: in the search of a sound mechanism for sound signaling in plants.

A signaling model is proposed to account for the molecular episodes that SVs induce within the cell, and in so doing a number of interesting questions that need to be addressed by future research in plant acoustics are uncovered.

Sound perception in plants.

Effects of hydric stress on vibrational frequency patterns of Capsicum annuum plants

It is proposed that the frequency changes of a plant’s vibration are related to the plant‘s hydric condition and that these frequency vibrations have the ecological potential to communicate water changes and levels of hydric stress.

Seminars in Cell & Developmental Biology Sound perception in plants

Can plants perceive sound? And what sounds are they likely to be “ listening ” to? The environment of plants includes many informative sounds, produced by biotic and abiotic sources. An ability to

Plants detect and respond to sounds

Specific sound patterns can affect plant development. Plants are responsive to environmental stimuli such as sound. However, little is known about their sensory apparatus, mechanisms, and signaling

Beyond Chemical Triggers: Evidence for Sound-Evoked Physiological Reactions in Plants

It is believed that sound wave treatment is a new trigger to help protect plants against unfavorable conditions and to maintain plant fitness.

Chemical Responses of Nicotiana tabacum (Solanaceae) Induced by Vibrational Signals of a Generalist Herbivore

Changes in the concentration of alkaloids in tobacco plants induced by VS produced by Phthorimaea operculella, a generalist caterpillar that naturally feeds on the plant, are studied to discuss the adaptive significance of plant responses to ecologically important VS stimuli.

Plants emit informative airborne sounds under stress

Stressed plants show altered phenotypes, including changes in color, smell, and shape. Yet, the possibility that plants emit airborne sounds when stressed – similarly to many animals – has not been



New phenotyping methods for screening wheat and barley for beneficial responses to water deficit.

Developments in infrared thermography provide new and feasible screening methods for detecting genetic variation in the stomatal response to water deficit in controlled environments and in the field.

Improved Performance of Transgenic Fructan-Accumulating Tobacco under Drought Stress

The introduction of fructans in this non-fructan-producing species mediates enhanced resistance to drought stress and the total nonstructural carbohydrate content was higher in the transgenic plants.


Carbon isotope ratios were correlated with the water use efficiency (WUE) and chlorophyll content and may be utilised for selection to further improve the WUE of A. saligna under drought conditions.

Plant gene responses to frequency-specific sound signals

It is proposed that in transgenic plants, specific frequencies of sound treatment could be used to regulate the expression of any gene fused to the ald promoter, suggesting that the 1,506 bp a Ald promoter is sound-responsive.

Regulation of leaf and fruit growth in plants growing in drying soil: exploitation of the plants' chemical signalling system and hydraulic architecture to increase the efficiency of water use in agriculture.

Findings show how an understanding of both root-to-shoot signalling mechanisms and fruit hydraulic architecture may explain observed increases in fruit quality, the differential effects of PRD on vegetative and reproductive production and the incidence of blossom end rot.

Assessing crop water stress of winter wheat by thermography under different irrigation regimes in North China Plain

Thermal imaging can be used as an indicator of water stress due to the closure of stomatal aperture. In this paper, we analyzed the robustness and sensitivity of thermography of winter wheat in the

Optimizing stomatal conductance for maximum carbon gain under water stress: a meta-analysis across plant functional types and climates

An analytical equation is developed to estimate k from gas exchange observations along gradients of soil water availability, providing a framework to assess the responses of leaf gas exchange to changes in water availability and can be extended to scale leaflevel fluxes to the canopy and ecosystem level.

Salt Tolerance of Canola in Relation to Accumulation and Xylem Transportation of Cations

ABSTRACT This study was conducted in a greenhouse to evaluate the root and shoot response of canola (Brassica napus L.) to salt-stress conditions and the remobilization, deposition, and input rate of

Genetic variation in stomatal and biochemical limitations to photosynthesis in the annual plant, Polygonum arenastrum

It is suggested that the range of trait constellations among lines of the annual plant, Polygonum arenastrum, represents a continuum between stress avoidance and stress tolerance and that genetic variation in these character combinations may be maintained by environmental variation in stress levels in the species’ ruderal habitat.
