种质资源的保存在很大程度上取决于种子的耐干燥性。旱生种子具有较强的抗旱性，是研究DT的优良模型。虽然已有一些实验策略被应用，但大多数方法难以应用于旱生种子。在本文中，我们试图综合目前种子DT研究的策略，并以柠条为例进行了深入的研究。首先，分析了旱生植物在种子DT研究中的先天优势。其次，我们总结了几种用于研究DT的策略，并举例说明了适合旱生植物的策略。在此基础上，提出了一种可行的技术策略，并阐述了旱生种子中存在的一些特殊分子机制。最后，提出了揭示旱生植物种子DT机制的几个步骤，并列出了该领域应考虑的三个科学问题。我们希望将这一策略优化利用到更多的旱生物种中，从而更系统地破译种子DT的生理和分子过程，为分子育种提供更多的候选基因。
Germplasm conservation strongly depends on the desiccation tolerance (DT) of seeds. Xerophytic seeds have strong desiccation resistance, which makes them excellent models to study DT. Although some experimental strategies have been applied previously, most methods are difficult to apply to xerophytic seeds. In this review, we attempted to synthesize current strategies for the study of seed DT and provide an in-depth look at Caragana korshinskii as an example. First, we analyze congenital advantages of xerophytes in the study of seed DT. Second, we summarize several strategies used to study DT and illustrate a suitable strategy for xerophytic species. Then, based on our previous studies work with C. korshinskii, a feasible technical strategy for DT re-establishment is provided and we provide illustrate some special molecular mechanisms seen in xerophytic seeds. Finally, several steps to unveil the DT mechanism of xerophytic seeds are suggested, and three scientific questions that the field should consider are listed. We hope to optimize and utilize this strategy for more xerophytic species to more systematically decipher the physiological and molecular processes of seed DT and provide more candidate genes for molecular breeding.
