耐旱藓类的抗旱生理及其机理研究

Advances of Research on Desiccation-tolerant Moss

耐旱藓类广泛分布于干旱及半干旱地区。本文综述分析了苔藓植物的耐旱能力和适应耐旱的形态结构和生理特征,从细胞和分子水平,对苔藓植物的耐旱机理进行了综述,并展望了我国苔藓植物的耐旱生理生态学研究前景。

Desiccation-tolerant moss exists in desertification-prone areas. This paper focuses on structural and physiological characteristics of desiccation-tolerant moss in defending against extreme droughts. The mechanisms of desiccation-tolerant response to desiccation from cell and moleculer level, including gene and protein, are reviewed. The meanings of researches on desiccation-tolerant moss are discussed. Some preliminary suggestions are given for further understanding the desiccation-tolerant moss in desertification-prone areas in northwestern China.
