doi:10.11924/j.issn.1000-6850.2012-3505

Abstract

Abstract: In recent years, drought brought a huge impact to crop growth in worldwide due to environmental transformation and the increasing scarcity of water resources. The mechanism of osmotic regulation, dehydration protection, antioxidant defense system, cell structure and the pathway of metabolic regulating were introduced systematically in this paper. The research progress of drought was reviewed from the signal factor, transcription factors and functional genes respectively. This paper summarized the plants activate many drought pathways to deal with drought stress through the intracellular multi-level and many regulation pathways. At last, the paper also discussed the problems existing in the research of drought, and the future research direction was given.
