Abstract: Abiotic stress is the most important factor that affect plant growth and development, plant stress resistance mechanism is a main area of plant molecular biology. With the development of molecular biology techniques, the research on plant abiotic stress has made great progress, and the molecular mechanism of plant response to stress has been revealed initially. This review discusses the abiotic stress related mechanism and molecular biology of Ammopiptanthus mongolicus under the drought, cold and salty stress, in order to identify more resources and new stress tolerance genes for plant genetic engineering and to provide ideas of plant stress resistance research.

Key words: abiotic stress, stress resistance, molecular biology, Ammopiptanthus mongolicus

摘要： 逆境胁迫是影响植物生长发育的重要因素,植物的抗逆机理是分子生物学研究的重要领域。随着分子生物学技术的发展,有关植物抗逆方面的研究已取得了很大的进展,初步揭示了植物应对逆境胁迫适应性的分子机理。沙冬青是我国温带荒漠地区惟一的常绿灌木,具有很强的抗逆性,是开展植物逆境胁迫研究和抗逆基因筛选的理想材料。本文综合论述了抗逆植物沙冬青的抗逆机理及逆境胁迫相关基因的分子生物学研究进展,为植物抗逆基因工程发掘更多的基因资源和抗旱植物的抗逆性研究提供思路。
