“…Changes in ion channel activities seem to play an important role in SV‐mediated cellular responses (Mishra et al 2016; de Melo 2023). One interesting finding of this work was the overexpression of five up‐regulated genes, including a putative cyclic nucleotide‐gated channel (CNGC) 18, involved in inorganic cation transmembrane transport in both sound treatments (1000 Hz and 1000 Hz + Pst DC3000).…”

“…Several reports have also described increases or decreases or lack of change in the activity of several antioxidant enzymes after sound treatments in various plant species and cell culture systems (Ghosh et al 2016; Hassanpour et al 2017). These variations in the antioxidant activities are probably due to differences in the sound pattern applied in terms of frequency, amplitude, exposure time, and repeatability (de Melo 2023). Additionally, the response of cells to SV treatment may vary depending on factors such as plant genotype, physiological state, and the organ, or tissue analyzed (de Melo 2023).…”

“…SVs of certain frequencies have been reported to provoke a suite of physiological, biochemical, and molecular changes in different crops and model plants. For example, SV were found to improve both seed germination and seedling vigor, photosynthetic rate, grain yield, postharvest shelf‐life of fruits, drought stress tolerance, plant immunity, and crop nutraceutical quality (for review see de Melo 2023; Demey et al 2023; Mishra et al 2016).…”

Sound vibrations (SV) are known to influence molecular and physiological processes that can improve crop performance and yield. In this study, the effects of three audible frequencies (100, 500 and 1000 Hz) at constant amplitude (90 dB) on tomato Micro‐Tom physiological responses were evaluated 1 and 3 days post‐treatment. Moreover, the potential use of SV treatment as priming agent for improved Micro‐Tom resistance to Pseudomonas syringae pv. tomato DC3000 was tested by microarray. Results showed that the SV‐induced physiological changes were frequency‐ and time‐dependent, with the largest changes registered at 1000 Hz at day 3. SV treatments tended to alter the foliar content of photosynthetic pigments, soluble proteins, sugars, phenolic composition, and the enzymatic activity of polyphenol oxidase, peroxidase, superoxide dismutase and catalase. Microarray data revealed that 1000 Hz treatment is effective in eliciting transcriptional reprogramming in tomato plants grown under normal conditions, but particularly after the infection with Pst DC3000. Broadly, in plants challenged with Pst DC3000, the 1000 Hz pretreatment provoked the up‐regulation of unique differentially expressed genes (DEGs) involved in cell wall reinforcement, phenylpropanoid pathway and defensive proteins. In addition, in those plants, DEGs associated with enhancing plant basal immunity, such as proteinase inhibitors, pathogenesis‐related proteins, and carbonic anhydrase 3, were notably up‐regulated in comparison with non‐SV pretreated, infected plants. These findings provide new insights into the modulation of Pst DC3000‐tomato interaction by sound and open up prospects for further development of strategies for plant disease management through the reinforcement of defense mechanisms in Micro‐Tom plants.

The functional significance and evolutionary relationships of BURP domain-containing genes unique to plants is of interest. Network analysis reveals different associations of BURP proteins with other proteins and functional terms, throwing light on their involvement in various biological processes and pathways. The gene expression data reveals that BURP genes are affected by salinity stress, reflecting diverse expression patterns in roots and shoots.
