The ability of plants to tolerate drought conditions is crucial for agricultural production worldwide. Recent progress has been made in our understanding of gene expression, transcriptional regulation and signal transduction in plant responses to drought. Molecular and genomic analyses have facilitated gene discovery and enabled genetic engineering using several functional or regulatory genes to activate specific or broad pathways related to drought tolerance in plants. Several lines of evidence have indicated that molecular tailoring of genes has the potential to overcome a number of limitations in creating drought-tolerant transgenic plants. Recent studies have increased our understanding of the regulatory networks controlling the drought stress response and have led to practical approaches for engineering drought tolerance in plants.
植物耐受干旱条件的能力对全球农业生产至关重要。我们对植物干旱响应中的基因表达、转录调控和信号转导的理解取得了新进展。分子和基因组分析推动了基因发现，并利用多个功能或调控基因进行基因工程，以激活与植物耐旱性相关的特定或广泛途径。多项证据表明，基因的分子改造有潜力克服创造耐旱转基因植物过程中的一些限制。最近的研究增进了我们对控制干旱胁迫响应的调控网络的理解，并带来了在植物中培育耐旱性的实用方法。
