Abstract: 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.

Key words: bryophyte, desiccation-tolerant, gene, protein
