涝渍胁迫降低芝麻产量。内涝应激的一个主要组成部分是淹没组织缺乏氧气。虽然在厌氧条件下生长的植物的形态和生理已经详细研究，有限的工作已经做了阐明适应在分子水平上。为了全面了解芝麻在基因组水平上对缺氧的反应，我们使用全基因组RNA-Seq分析在缺氧处理后36小时内的两个时间点进行了基因表达谱分析。我们确定了一组显着的积极和消极表达的基因（诱导和抑制，分别）在缺氧与不同的时间配置文件。受影响的基因与糖酵解、氮代谢、淀粉和蔗糖代谢以及植物激素信号转导相关，并表明京都基因和基因组百科全书中特定途径（糖酵解/糖原生成）的上调。此外，黄酮和黄酮醇生物合成、类固醇生物合成、光合作用、半胱氨酸和蛋氨酸代谢、谷胱甘肽代谢、苯丙素类生物合成、剪接体、昼夜节律等途径的基因表达也发生了显著变化。
Waterlogging stress lowers yields in sesame (Sesamum indicum L.). A major component of waterlogging stress is the lack of oxygen available to submerged tissues. Although the morphology and physiology of plants grown under anaerobic conditions have been studied in detail, limited work has been done to elucidate adaptations at the molecular level. To gain comprehensive insight into how sesame responds to hypoxia at the genome level, we performed gene expression profiling at two time points during a 36-h period following hypoxic treatment using a whole-genome RNA-Seq analysis. We identified sets of significantly positively and negatively expressed genes (induced and repressed, respectively) in response to hypoxia with distinct temporal profiles. The genes that were affected were associated with glycolysis, nitrogen metabolism, starch and sucrose metabolism and plant hormone signal transduction and indicated the upregulation of particular pathways (glycolysis/glycogenesis) in the Kyoto Encyclopedia of Genes and Genomes. Moreover, significant changes in the expression of genes were found for pathways, including flavone and flavonol biosynthesis, steroid biosynthesis, photosynthesis, cysteine and methionine metabolism, glutathione metabolism, as well as phenylpropanoid biosynthesis, spliceosome, circadian rhythm.
