Abstract

We examined the responses of sound-treated arabidopsis adult plants to water deprivation and the associated changes on gene expression. The survival of drought-induced plants was significantly higher in the sound treated plants (24,8%) compared with plants kept in silence (13,3%). RNA-seq revealed significant upregulation of 87 genes including 32 genes involved in abiotic stress responses, 31 involved in pathogen responses, 11 involved in oxidation-reduction processes, 5 involved in the regulation of transcription, 2 genes involved in protein phosphorylation/dephosphorylation and 13 involved in jasmonic acid or ethylene synthesis or responses. In addition, 2 genes involved in the responses to mechanical stimulus were also induced by sound, suggesting that touch and sound have at least partially common perception and signaling events.

摘要

我们研究了经过声音处理的拟南芥成年植株对水分剥夺的反应以及基因表达的相关变化。与处于安静环境中的植株(13.3%)相比,经过声音处理的植株中干旱诱导植株的存活率显著更高(24.8%)。RNA测序显示87个基因显著上调,其中包括32个参与非生物胁迫反应的基因、31个参与病原体反应的基因、11个参与氧化还原过程的基因、5个参与转录调控的基因、2个参与蛋白质磷酸化/去磷酸化的基因以及13个参与茉莉酸或乙烯合成或反应的基因。此外,2个参与机械刺激反应的基因也被声音诱导,这表明触觉和声音至少部分具有共同的感知和信号传导事件。
