大多数高等植物不能在干燥到空气干燥的状态下存活。一个例外是一小群维管被子植物，称为复活植物。它们已经进化出独特的耐干燥机制，因此可以耐受严重的水分损失，并且大多数情况下会随着环境中的相对湿度来调节其含水量。脱水耐受性是一个复杂的现象，依赖于脱水和随后的再水化过程中许多基因的调控表达。大多数复活植物具有较大的基因组，并且难以转化，这使得它们不适合遗传方法。然而，技术的进步使大规模分析基因表达的变化成为可能。这些方法与非耐干燥植物的比较研究提供了新的见解，干燥耐受性所需的分子过程，并将揭示与未知功能的孤儿基因的识别。在这里，我们回顾了最近大规模的转录组学，蛋白质组学和代谢组学的研究，已进行耐干燥植物，并讨论这些研究如何有助于了解耐干燥的分子基础。
Most higher plants are unable to survive desiccation to an air-dried state. An exception is a small group of vascular angiosperm plants, termed resurrection plants. They have evolved unique mechanisms of desiccation tolerance and thus can tolerate severe water loss, and mostly adjust their water content with the relative humidity in the environment. Desiccation tolerance is a complex phenomenon and depends on the regulated expression of numerous genes during dehydration and subsequent rehydration. Most of the resurrection plants have a large genome and are difficult to transform which makes them unsuitable for genetic approaches. However, technical advances have made it possible to analyze changes in gene expression on a large-scale. These approaches together with comparative studies with non-desiccation tolerant plants provide novel insights into the molecular processes required for desiccation tolerance and will shed light on identification of orphan genes with unknown functions. Here, we review large-scale recent transcriptomic, proteomic, and metabolomic studies that have been performed in desiccation tolerant plants and discuss how these studies contribute to understanding the molecular basis of desiccation tolerance.
