摘　　要：作为植物演化过程中的先锋植物,苔藓植物有其特殊适应机制来应对环境的变化,能在其他植物不能生长的极端环境中生长.砂藓属(Racomitrium)植物是典型的耐脱水藓类,能在裸露的岩石表面和沙土上生长.砂藓属植物广泛分布于世界各地,其抗逆性研究和抗逆基因的挖掘越来越受关注,且目前已取得了一些进展,多个砂藓属植物中的基因已被克隆并进行了抗旱和抗高温功能的验证.对近年来砂藓属植物的抗逆功能进行概述,包括抗旱、耐高温、重金属富集等,旨在为后续砂藓属植物抗逆性研究提供参考依据.As the pioneer plants in the process of plant evolution,bryophytes have special adaptive mechanisms to cope with environmental changes,can grow in the extreme environment where other plants cannot.Racomitrium plants are typical desiccation-tolerant mosses,can grow on the bare rock surfaces and sandy soils.Racomitrium plants are widely distributed all over the world,the researches on stress resistance and the mining of stress resistance genes of the Racomitrium plants have been attracted more and more attention,and some progresses had been made up to now,many genes of the Racomitrium plants have been cloned and their functions of drought resistance and high temperature resistance have been verified.The stress resistance of Racomitrium plants in recent years was summarized,including drought resistance,high temperature resistance,heavy metal enrichment,and other aspects,in order to provide references for subsequent researches on stress resistance of Racomitrium plants.
