Plants are analogous to animals by responding physiologically and phenotypically to environmental changes. Until recently, the meaning of sound in the plant's life remains undiscovered. In this study, we investigated the role of music in response to heat stress and its application in memory and associative learning for stress tolerance in Arabidopsis. Significant upregulation of heat-responsive genes (HSFA3, SMXL7, and ATHSP101) in response to music suggests music has an advantage during heat stress. Moreover, the defensive conditioning experiment showed that plant learns to associate music with stress (heat) and elicit better response compared to music alone. Two heat-responsive genes, HSFA3 and ATCTL1, which are well known for their interaction and regulation of an array of heat shock proteins were found to play a key role in associative learning for heat stress in Arabidopsis. Our experiment highlights the application of sound in plant conditioning and as a stress reliever. Nonetheless, the persistence of memory awaits further experiments. We foresee the potential of artificial sound as an environment-friendly stimulus in conditioning the crops for upcoming stresses and reduce the yield loss, as an alternative to breeding and genetic modifications.
植物在生理和表型上对环境变化做出反应，这一点与动物类似。直到最近，声音在植物生命中的意义仍未被发现。在本研究中，我们调查了音乐在拟南芥应对热胁迫中的作用及其在记忆和联想学习以提高胁迫耐受性方面的应用。热响应基因（HSFA3、SMXL7和ATHSP101）对音乐有显著上调反应，这表明音乐在热胁迫期间具有优势。此外，防御性条件实验表明，植物学会将音乐与胁迫（热）联系起来，与单独听音乐相比能引发更好的反应。发现两个热响应基因HSFA3和ATCTL1在拟南芥热胁迫联想学习中起关键作用，它们以与一系列热休克蛋白的相互作用和调节而闻名。我们的实验突出了声音在植物条件训练和作为应激缓解剂方面的应用。尽管如此，记忆的持久性仍有待进一步实验验证。我们预见人工声音作为一种环境友好型刺激物，在使作物适应即将到来的胁迫并减少产量损失方面具有潜力，可作为育种和基因改造的替代方法。
