摘要:

干旱显著影响植物各阶段的生长发育、各种生理生化代谢过程和生态环境,是植物成活与生长的重要限制因素之一,随着现代分子生物学的发展,从分子水平研究植物抵御干旱等逆境的机理已成为农业研究的一个重要任务。从植物抗旱性鉴定评价体系和抗旱机制研究两个方面对近年来植物抗旱性研究进展进行了综述,以期为今后植物抗旱分子机制的研究和改良植物抗旱性的分子遗传育种工作提供参考。

Abstract:

Drought affects the growth and development of plants at every phase and various physiological metabolic processes in plants,and ecological environment. It is one of the most disastrous limiting factors for growth and survival of plants. With the development of molecular biology,studying the regulation mechanisms of stress resistances at molecular scale has been become the key task in agricultural research. This paper describes the advances in drought resistance of plants in recent years based on two aspects:the identification and evaluation system of drought resistance in plant,and the mechanism of drought resistance,which aims at providing reference and strategies for plant drought resistance molecular mechanism research and molecular genetic breeding in plant drought resistance improvement.

Key words: plants, drought resistance, identification method, evaluated index, drought resistance mechanism
