通过采用两种不同类型的全面的转录组数据集，这是向公众提供的，我们问了一个关键问题，是否有任何显着的相关性之间的昼夜振荡基因在光/暗的日常周期和睡眠响应基因。研究的激素有阿坝、乙烯、油菜素内酯、细胞分裂素、赤霉素、生长素和茉莉酸。结果表明，在光/暗周期中，大量ABA响应基因和/或茉莉酸甲酯（MJ）响应基因的表达每天都在强烈振荡。这项研究的结果表明，植物胁迫反应的某些方面，基本上是由阿坝和/或MJ介导的，可能每天都受到调节，虽然在转录水平上的生物钟功能，以准备适当的行动，对常见的环境压力，通过预期的昼夜周期。
By adopting two distinct types of comprehensive transcriptome data sets, which are available to the public, we asked the critical question as to whether or not there is any significant correlation between diurnally oscillating genes during the light/dark daily cycle and hormone-responsive genes. The hormones studied here were ABA, ethylene, brassinosteroid, cytokinin, gibberellin, auxin and jasmonate. It was revealed that the expression of a significantly large number of ABA-responsive and/or methyl jasmonate (MJ)-responsive genes oscillate diurnally and robustly during the light/dark cycle. The results of this study implied that some aspects of plant stress responses, basically mediated by ABA and/or MJ, might be regulated daily though the circadian clock function at the level of transcription in order to prepare properly for action against common ambient stresses by anticipating the diurnal day/night cycle.
