“Out of sight, out of mind”. The antagonistic role of the transcriptional memory associated with repeated acoustic stimuli on the priming of plant defense.
Facilitating plant defense through priming holds significant promise for advancing sustainable crop health practices. The primed state of plants is correlated with a more rapid and efficient response, achievable by subjecting plants to recurrent stressors. Consequently, priming constitutes a dynamic transitional process between two distinct biological states, necessitating the establishment and maintenance of transcriptional memory mechanisms. Research on transcriptional memory has revealed molecular mechanisms including protein and transcription factor accumulation, as well as epigenetic modulations. Nonetheless, there remains a dearth of understanding regarding the interplay among the dynamics of transcriptional stress memory, its preservation, and the resultant emergent properties conferred upon the organism once primed. Here, we found that the robustness of transcriptional memory associated with repeated mechanical stimuli played an antagonistic role in the priming of plant defense
