Molecular and genomic studies have shown that several genes with various functions are induced by drought and cold stresses, and that various transcription factors are involved in the regulation of stress-inducible genes. The products of stress-inducible genes function not only in stress tolerance but also in stress response. Genetic studies have identified many factors that modify the regulation of stress responses. Recent progress has been made in analyzing the complex cascades of gene expression in drought and cold stress responses, especially in identifying specificity and crosstalk in stress signaling.
分子和基因组研究表明，干旱和寒冷胁迫可诱导多个具有不同功能的基因，并且多种转录因子参与应激诱导基因的调控。应激诱导基因的产物不仅在胁迫耐受性中发挥作用，还参与应激反应。遗传学研究已经鉴定出许多影响应激反应调控的因子。在分析干旱和寒冷胁迫反应中基因表达的复杂级联反应方面，尤其是在确定应激信号传导的特异性和相互作用方面，已经取得了新进展。
