Plant drought tolerance is a complex trait that requires a global view to understand its underlying mechanism. The proteomic aspects of plant drought response have been extensively investigated in model plants, crops and wood plants. In this review, we summarize recent proteomic studies on drought response in leaves to reveal the common and specialized drought-responsive mechanisms in different plants. Although drought-responsive proteins exhibit various patterns depending on plant species, genotypes and stress intensity, proteomic analyses show that dominant changes occurred in sensing and signal transduction, reactive oxygen species scavenging, osmotic regulation, gene expression, protein synthesis/turnover, cell structure modulation, as well as carbohydrate and energy metabolism. In combination with physiological and molecular results, proteomic studies in leaves have helped to discover some potential proteins and/or metabolic pathways for drought tolerance. These findings provide new clues for understanding the molecular basis of plant drought tolerance.
植物耐旱性是一个复杂的性状，需要从全局角度来理解其潜在机制。在模式植物、农作物和木本植物中，已经对植物干旱响应的蛋白质组学方面进行了广泛研究。在本综述中，我们总结了近期关于叶片干旱响应的蛋白质组学研究，以揭示不同植物中常见和特殊的干旱响应机制。尽管干旱响应蛋白根据植物物种、基因型和胁迫强度呈现出各种模式，但蛋白质组学分析表明，主要变化发生在感知和信号转导、活性氧清除、渗透调节、基因表达、蛋白质合成/周转、细胞结构调节以及碳水化合物和能量代谢等方面。结合生理和分子研究结果，叶片的蛋白质组学研究有助于发现一些潜在的耐旱蛋白质和/或代谢途径。这些发现为理解植物耐旱性的分子基础提供了新线索。
