Plant growth and productivity are greatly affected by environmental stresses such as drought, high salinity, and low temperature. Expression of a variety of genes is induced by these stresses in various plants. The products of these genes function not only in stress tolerance but also in stress response. In the signal transduction network from perception of stress signals to stress-responsive gene expression, various transcription factors and cis-acting elements in the stress-responsive promoters function for plant adaptation to environmental stresses. Recent progress has been made in analyzing the complex cascades of gene expression in drought and cold stress responses, especially in identifying specificity and cross talk in stress signaling. In this review article, we highlight transcriptional regulation of gene expression in response to drought and cold stresses, with particular emphasis on the role of transcription factors and cis-acting elements in stress-inducible promoters.
植物的生长和生产力受到干旱、高盐度和低温等环境胁迫的极大影响。在各种植物中，这些胁迫会诱导多种基因的表达。这些基因的产物不仅在胁迫耐受性中发挥作用，还在胁迫反应中起作用。在从胁迫信号感知到胁迫响应基因表达的信号转导网络中，胁迫响应启动子中的各种转录因子和顺式作用元件对植物适应环境胁迫发挥作用。在分析干旱和寒冷胁迫响应中基因表达的复杂级联反应方面，尤其是在确定胁迫信号传导中的特异性和相互作用方面，最近取得了进展。在这篇综述文章中，我们重点介绍了响应干旱和寒冷胁迫的基因表达的转录调控，特别强调了转录因子和顺式作用元件在胁迫诱导启动子中的作用。
