| 中文摘要: |
| 综述了目前关于脱水素（Dehydrin，DHN）的研究进展，包括脱水素的蛋白结构特征、细胞定位及作用机制，脱水素在生物及非生物逆境下的转基因研究，脱水素的磷酸化修饰，脱水素的结合金属离子、清除活性氧、作为分子伴侣
保护酶活性等特性。展望了利用现代生物技术将脱水素用于提高植物对逆境的耐受力的应用前景，提出今后还需在脱水素作用机制、基因家族功能与生物胁迫相关性等几个方面进行深入研究。 |
| 英文摘要: |
| The research advances about plant dehydrin, including its protein structure, its celluar localization and mechanism of action, the transgenic research of dehydrin under biotic or abiotic stresses, the phosphorylation modifications of dehydrin, and the biological roles of dehydrin (metal ions binding, reactive oxygen species scavenging and protection of chill sensitive enzymatic activity as molecular chaperones), were reviewed. Meanwhile, the prospect of applying dehydrin to improve the tolerance of plants against stresses by biotechnology was expected. The research tendencies about dehydrin in the future, such as its mechanism of action, its function of gene family, and its correlation with biotic stresses were proposed. |
